Abstract:As the only one of its kind, China National Digital Geological Map (Public Version at 1:200000 scale) Spatial Database (CNDGM-PVSD) is based on China's former nationwide measured results of regional geological survey at 1:200 000 scale, and is also one of the nationwide basic geosciences spatial databases jointly accomplished by multiple organizations of China. Spatially, it embraces 1163 geological map-sheets (at scale 1:200 000) in both formats of MapGIS and ArcGIS, covering 72% of China's whole territory with a total data volume of 90 GB. Its main sources is from 1:200 000 regional geological survey reports, geological maps, and mineral resources maps with an original time span from mid-1950s to early 1990s. Approved by the State's related agencies, it meets all the related technical qualification requirements and standards issued by China Geological Survey in data integrity, logic consistency, location accuracy, attribution fineness, and collation precision, and is hence of excellent and reliable quality. The CNDGM-PVSD is an important component of China's national spatial database categories, serving as a spatial digital platform for the information construction of the State's national economy, and providing information backbones to the national and provincial economic planning, geohazard monitoring, geological survey, mineral resources exploration as well as macro decision-making.

Abstract:The new 1:50 000 Hydrogeological Survey Dataset for Poverty Alleviation (also referred to as the Dataset) carried out in Xingguo County and Ningdu County, South Jiangxi is based on a water exploration project which aimed at alleviating poverty in southern Jiangxi under the unified deployment of the China Geological Survey, and the Ministry of Natural Resources of the People's Republic of China. It contains the results obtained from the survey designed to address the water shortage suffered by the people in local mountainous areas and to develop green water industries such as mineral water production for the local government. The Dataset comprises five sets of data:basic data of seven boreholes, stratum description information of seven boreholes, preliminary survey result of mineral water (21 survey points), analysis results of mineral water (15), and analysis results of drinking water (4), obtained from the project entitled 1:50 000 Environmental Geological Survey along High-speed Railway Lines of Xianning-Yueyang and Nanchang-Huaihua in City Clusters of Middle Yangtze River (initiated by Hydrogeological and Environmental Geological Survey, China Geological Survey, Baoding) from January to September 2017. Among these data, the basic data and stratum description information of boreholes mainly include information on boreholes such as location, diameter, depth, single well water yield, borehole sampling, stratum era and stratum bottom depth (m) revealed by the boreholes, as well as stratum lithology description. The preliminary survey result for mineral water mainly includes the location, on-site test indices, and origin analysis of the survey points. The analysis results for mineral water and drinking water came from lab tests of water samples obtained in the implementation of the project. Using the boreholes, the water shortage faced by 3 000 people has been directly addressed. Furthermore, the discovery of high-quality mineral water has provided new ideas for local economic growth.

Abstract:Duobuza Copper Deposit in Tibet, the first large-scale porphyry copper deposit discovered along Pangong Lake-Nujiang River metallogenic belt in recent years, is situated in Duobuza tectonic magmatic arc in the northern margin of Pangong Lake-Nujiang River suture zone. It was formed during the evolution period of archipelagic arc-basin system of Pangong Lake-Nujiang River of Early Cretaceous with metallogenic age of 120 Ma. The deposit is related to quartz diorite porphyrite and granodiorite-porphyry intrusions in the strata of Meiriqiecuo Formation of Early Cretaceous. Boasting of present measured resources of Cu and Au of 2.30 million tonnes and 92 tonnes with average grade of 0.51% and 0.2 g/t respectively, Duobuza Copper Deposit ranks as one of the super large-scale deposits and one of the national strategic reserve bases of mineral resources. The dataset of resource reserves in Duobuza Porphyry Copper Deposit of Tibet is built based on the valuable data obtained in the mineral survey during 2005-2010. It contains 10 data tables, in which the grades and relevant calculated results of single-engineering industrial ore bodies and low-grade ore bodies in Duobuza Copper Deposit are mainly included. Furthermore, all detailed data related to reserve calculation are summarized and collated systematically in the dataset.

Abstract:This dataset contains 2 602 sets of test data on 234 rock and soil samples collected from the cores of 14 geological engineering boreholes that were drilled in the Pingluo Station map sheet area of Yinchuan Basin (also referred to as "the Area") in 2017. It primarily consists of information about the shear strength, compression modulus and grain composition of soil masses. In the Area, the geological structures of the Quaternary, which is formed by many causes and has a great thickness, compose the main geological engineering formation, since it is widely distributed. From west to east they include:diluvium of the Upper Pleistocene Series, in which gravels and sandy gravels are mainly distributed; fine sandy soil of the Lingwu Formation, Holocene Series; lacustrine sediment of the Holocene Series, throughout which sludge, sandy clay and silty sand are mainly distributed; aeolian deposits of the Holocene Series, in which khaki medium-fine sand and silty sand are mainly distributed. Among these geological structures, the Lingwu Formation of the Holocene Series covers most of the Area and mostly contains fine sand, silty sand and sandy clay. As revealed by the boreholes, vertically, the strata of the plain area of the Yinchuan Basin mainly consist of fine sand and silty sand of fluviatile-lacustrine facies that are interspersed with silty clay, whilst gravel-cobble layers are found in some boreholes. According to analysis of sample testing data, the gravel soil, alluvial sandy soil and cohesive soil in the Area are subject to good geological engineering conditions due to their high shear strength, while the sandstones and mudstones in the northwest suffer from poor geological engineering conditions since they are moderately or strongly weathered and interspersed with weak intercalations. In addition, the sludge, sandy clay and silty sand of lacustrine sedimentary origin also suffer from poor geological engineering conditions. The data obtained for the dataset are credible and can accurately reflect the strata information as well as the physical and mechanical properties of the rock and soil masses in the Area since the geological engineering drilling was conducted in a standardized manner and the tests and analysis were all performed by nationally-certified laboratories.

Abstract:The basement strata outcropping on the northern margin of the upper Yangtze and North Sichuan have developed a dual-layer structure, where medium-large and extra-large graphite deposits have been found at Jianshan, Pinghe and Miaoping etc., which are located on fold basements in the upper layer. Until recently, however, a graphite deposit is found in fine-grain quartzite of the Wangjiaping Formation, Houhe Group complex of the crystalline basement in its lower part. The rock mass is about 200 m long, 6.7 m wide, 4.9 m thick on average and 5.13% in average grade. The ore combination is quartz + graphite + mica + pyrite + hematite. This discovery on the northern margin of the upper Yangtze expands the prospecting foreground in the region, provides new opportunities to prospect crystalline graphite ores therein and gives a new guarantee in resource potential to build an extra-large crystalline graphite ore base in Bazhong, Sichuan. The dataset contains data in Excel sheets, including 2 type files *.xls, recording results from fixed carbon testing of samples and data from oxide testing.

Abstract:In order to develop this dataset, data were acquired comprehensively by using multiple methods such as mapping which is specific for lithology, structures and mineralized alterations, remote-sensing, geophysical/geochemical and drilling exploration. A route of 520.65 km was surveyed, with 2 047 stream sediment samples and 167 chemical analytical samples collected, and 461 km² area interpreted based on remote-sensing data. Emphasis was placed on survey and division of early-Yanshanian metallogenic magmatite, ore-bearing formations, rock-control and ore-control structures, and mineralized alteration marks etc., so that it could be verified that the main metallogenic geological bodies for Au-Ag multi-metal ores within the area were early-Yanshanian granodiorite and that the rock-control and ore-control formations were a NE-strike thrust fault and its secondary fissures. Building on this, the 1: 50 000 formation and tectonic map of the Yinkeng Map-sheet was compiled, the mineral geological map dataset was established by using a digital mapping system (DGSS), a map layer property database on key formations & tectonics, geological boundaries, fractures and magmatite etc. was comprehensively compiled; the prospecting prediction model for Yinkeng-style mid-low temperature post-magmatic hydrothermal deposits in the area was improved, highlighting the causal relationship between deposits and the formations or structures in the area.

Abstract:The Qingtang map-sheet is located to the north of the Yudu Yingkeng-Ningdu Qingtang integrated survey area, south Jiangxi, and in the north of the Yushan metallogenic sub-zone. To develop this dataset, data were acquired comprehensively by using multiple methods such as mapping specific to lithology-structures-altered mineralization, remote sensing, geophysical/geochemical and drilling exploration. A route of 533.68 km was surveyed for mineral geology, with 1 729 stream sediment samples and 119 chemical analytical samples collected, 458 km² of land measured with the 1:50 000 ground high-precision magnetic method and interpreted based on remote-sensing data, as well as 422m of depth drilled. In the dataset, emphasis is placed on survey and division of early-Yanshanian metallogenic magmatite, ore-bearing formations, rock-controlled and ore-controlled structures, and mineralized alteration marks etc. It is clear that biotite granite is a metallogenic geologic body of skarn-type S-Fe-W multi-metal ores, the main metallogenic structural plane is the Si-Ca heterologous interface in the upper part of the Zishan Formation, and alteration is mainly through skarnization, marbleization etc. The project team has plotted the Qingtang Map-sheet formation and structural map, created the mineral database of the area, and compiled properties of the main formation structures, fractures, geological boundaries and magmatite etc. This has improved the prospecting prediction model for Shihoushan-styled, S-Fe-W multi-metal deposits and highlighted the causal relationship between deposits and tectonic formations in the area.

Abstract:The geochemical dataset of the 1:50 000 Shandong Biguo map sheet area (also referred to as "the Area") was achieved by carrying out a mineralogical survey of the Area based on the project entitled Mineral Survey and Prospecting Prediction of Integrated Exploration Areas of the Gold Deposits in the Shandong Zhaoyuan-Laizhou Area initiated by the China Geological Survey, as well as through extensive data collection of geological information, geophysical prospecting, geochemical prospecting, remote sensing, and mineralogy. A total of 1 875 stream sediment samples were collected, with sampling size fractions of -10~+80 mesh and an average sampling density of 4.5 sampling points per km². Furthermore, 16 elements were analyzed by the methods of inductively coupled plasma mass spectrometry (ICP-MS), atomic fluorescence spectrometry (AFS), powder emission spectrometry (ES), and graphite furnace atomic absorption spectrometry (GF-ASS). The final geochemical dataset contains an Excel file and an atlas. The Excel file consists of the original analysis data of 16 elements from the 1 875 samples. The atlas comprises one mineralogical map, one sampling point bitmap and 16 element-specific geochemical maps. A total of 149 geochemical anomalies of single elements and 10 integrated anomalies were discovered in the Biguo map sheet area, as a result of this work. In addition, five prospecting target areas of gold deposits were determined through examining the information obtained from the geological investigation, mineralogical survey, geophysical prospecting, geochemical prospecting and remote sensing.

Abstract:The 1:100 000 mineralogical dataset of the Gouli Gold Deposit integrated exploration area in Dulan County, Qinghai Province (also referred to as "the Area") consists of a systematic database, tectonic formation maps, mineralogical maps, geomagnetic ΔT plane isoline maps, geomagnetic ΔT RTP plane isoline maps, geochemical integrated anomalies maps, mineral prediction result maps, and attached tables. In the folder of each map, there are the corresponding preparation manuals for the map. The Area is divided into four second-order tectonic units by the Central Suture Zone of the East Kunlun Orogenic Belt from the Neoproterozoic Era to the Early Paleozoic Era (from Pt₃ to the end of P₂), the Xinghai-Kuhai Suture Zone from the Middle Paleozoic Era to the Late Paleozoic Era (from D to P₃), and the A'nyemaqen Suture Zone from the Late Paleozoic Era to the Early Mesozoic Era (from C to the end of T₂). The magmatic activities in the Area mainly occurred from the Ordovician to the Devonian and from the Permian to the Triassic, which represents two different orogenic cycles. The metallogenic period may be from the Late Triassic Epoch to the Early Jurassic Epoch. A total of 21 magnetic anomalies and 80 geochemical integrated anomalies on a scale of 1:50 000 were delineated in the Area. Furthermore, four grade Ⅲ metallogenic belts (areas), seven grade IV metallogenic sub-belts, eight grade V metallogenic belts (ore fields), and 17 grade VI favorable prospecting blocks were determined. 14 prospecting target areas were screened and submitted in the favorable prospecting blocks. In addition, a number of mineral deposits (occurrences) with prospecting potential were found in the Area through follow-up work, such as the Nagenkangqieer large-scale silver deposit, the Delong gold deposit, the Mailong gold occurrence, the Langmuri copper-nickel occurrence, and the Longshigeng copper-cobalt occurrence. It is estimated that the total amount of gold, silver, lead-zinc and copper-cobalt resources in the Area are 588.04 tons, 3 197.85 tons, 2 358 300 tons, and 1 214 900 tons respectively.

Abstract:Metal mineral resources serve as the material basis for economic and social development. In this paper, the data such as reserves, production and consumption of raw ore, as well as trade volume (including trade amount), of 16 kinds of metal mineral resources in the world and China from 2006 to 2017 that have an important impact on the economic development of China were collected. The 16 kinds of resources include bulk minerals in short supply (iron Fe, manganese Mn, copper Cu, aluminium Al, gold Au, lead Pb, zinc Zn, nickel Ni, and chromium Cr), dominant minerals (tungsten W, molybdenum Mo, tin Sn, and antimony Sb), and strategic emerging minerals (lithium Li, cobalt Co, and titanium Ti). The dataset consisting of the data collected is in Excel format and comprises six sheets (including Resources in the World, Identified Resource Reserves in China, Reserves Base in China, Raw Ore Production in China, Raw Ore Consumption in China, and Import-Export Volume of China), aiming to analyze the present status as well as the supply and demand trends of the important metal minerals required in the middle and late stages of the industrialization process of China. The following information is shown from the dataset. In terms of bulk minerals in short supply such as Fe, Mn, Cu, and Au, although identified resource reserves have increased steadily, the basic reserves have grown slowly due to the large volume of exploitation and consumption. With the total demand for bulk minerals in short supply still remaining high in the future, the import volume will continue to climb as a result of low resource guarantee degree in China. In terms of dominant minerals such as W and thorium (Th), they are no longer as dominant as before owing to low reserves-to-production ratio and insufficient backup resources. In terms of strategic emerging minerals including Li, Co and Ti, the resources and basic reserves have grown slowly or declined. The quality of these minerals in China is poor, making it difficult to utilize many of them. Moreover, the production and consumption of these minerals have grown rapidly in the past ten years and will continue to grow at a high rate in the future, whereas domestic reserves grow slowly, resulting in a prominent contradiction between supply and demand. The supply and demand data of the existing metal minerals are examined and summarized in this dataset, in order to provide references for exploration and strategic deployment of metal mineral resources in the future.
