Abstract:For the thematic Program on China's national mineral resources' potentials assessment (2006-2013), the research group has collected such abundant references as 1:50, 000, 1:200, 000 and 1:250, 000 regional geological survey data (including the 1:250, 000 regional geological survey results from the Qinghai-Tibet plateau in 1999-2005), geological research results, scientific research monographs and important geological literatures as well as geophysical, geochemical, and remote sensing prospecting inferred results. Having digested all these data, the group has compiled serial first-hand data map-sheets at scale of 1:250, 000 and created the spatial database for the metallogenic geological setting researches. Applying the suite-tectonic analysis method and map-compiling techniques with such modern information technologic means as data models, quality-controlling models, and GIS software, the group has further compiled multiple map-sheets, created new databases, and summarized and integrated all these results in line with standard serial map-sheets, and has established the spatial database of serial suite-tectonic map-sheets of mainland China (1:250, 000). The database has included 729 map-sheets as well as their corresponding compilation explanatory notes and map-compiling metadata, roughly covering the entire mainland China. Compared with the traditional edition of the geological maps database which is characterized by using the stratigraphic units of System and Formation as the basic map-compiling units, this database has some outstanding advantages. Firstly, the essential mapping elements in the principal map are as fine as lithological units (quasi-Member), which are actually the finest mapped lithological components under the lithostratigraphic unit ‘Formation’. Secondly, different occurrences of the lithological units are expressed with the respective lithological patterns, objectively presenting the physical tracks and lineaments of lithological suites and geological structures, systematically reflecting the geological processes and their evolutionary characteristics, and being convenient for direct map reading and utilization. In general, this database can provide fundamental information for the compilation of 1:500, 000 or smaller scaled tectonic map-sheets, can directly offer essential factors for 1:250, 000 and smaller scaled regional mineral resources prediction, and can supply thematic base maps of geological structures for 1:250, 000 and smaller scaled minerogenetic regularity researches. It has also held extensive and long-term values for duplicative utilizations in geological survey and ore-prospecting, geo-hazard mitigation, hydrological, engineering and environmental geological surveying, geothermal resources exploration, and ecological conservation.

Abstract:China Regional Geochemical Exploration Database is the first one of its kind that synthesizes the testing data of 39 elements and their oxides from the regional geochemical exploration respectively at scales of 1:200, 000 and 1:500, 000, covering 28 provinces (autonomous regions and municipalities directly under the central government). It features nearly 55.4 million pieces of data collected from 1.42 million data points. The data involves 1, 299 map sheets at scale of 1:200, 000 and 18 map sheets at 1:500, 000. It is China's first massive geochemistry database. The national mineral resources potential evaluation project updated the database, making the national geochemical exploration database cover over 1.47 million records of aggregated data, with the data reaching 63.21 million records. On this basis, more than 40, 000 geochemical maps have been compiled, and a spatial database has been established to provide rich geochemical information for carrying out geochemistry research and predicting mineral resources. This pioneering work is of great significance to improve the level of geochemical exploration and research in China. It provides the most fundamental data for studying regional geochemical distribution of metallogenic elements, ecological environment, and basic geology, as well as for mineral resources prospecting throughout China.

It provides basic data not only for analyzing the present situation of mineral resources in China, but also for decision-making of exploring mineral resources in China in the future.

Abstract:Energy and mineral resources constitute a country's strategic resources for national security and economic development. It is of paramount importance to strengthen research and development (R&D) on oil, gas, coal and other energy resources in China and surrounding regions. According to plate tectonics, continental dynamics and geological theory of oil, gas and coal reservoir, with the research thought of deep structure controlling the basin-range development, basin-range coupling and geothermal dynamical system controlling the mineralization, by the basic geological data of 70 oil and gas fields and 471 coal fields, in aspects such as the regional geological characteristic, metallogenic geological condition and metallogenic unit of sedimentary basin development, the spatial-temporal distribution law of plate tectonic pattern and energy resources of the area are prompted on the GIS platform. The energy resources in Southern China and adjacent areas may be divided into three metallogenic domains. Therein, each tectonic metallogenic domain may be subdivided into metallogenic regions of four levels:metallogenic province, ore-bearing area (basin), ore field aggregation zone (belt), and ore field (oil and gas field). Moreover, the dataset is composed of type and time of tectonic zone (fault zone and orogenic belt), type and time of basin, type and abundance of energy and mineral resources, metallogenic province and belt, and other metadata. Based on regional tectonic research, this dataset is a complete database established by GIS. It is in line with the evaluation data of energy and mineral resources (oil, natural gas, coal) of sedimentary basin, and the comprehensive analysis of the characteristics of metallogenic provinces and belts. It not only features the integration of regional geological cognition and energy resource prospection achievements of sedimentary basin in Southern China and adjacent areas, but also the theoretical foundation for the scientific direction of geological prospecting deployment of the State.

Abstract:The Dataset of Metallogenic Provinces (belts) in Southern Northeast Asia (SNA) is based on the latest geosciences data of the area understudy. It takes into account the regional geo-tectonic features and metallogenic characteristics, while synthesizing the data of 1, 590 mineral occurrences in the country and abroad. In addition, it classifies the SNA as 3 metallogenic mega-provinces, 9 provinces, 43 belts, and 11 sub-belts, according to the distribution of major metallic ore deposits, types of ore deposit, metallogenic epochs, and metallogenic regularities. This dataset covers name of metallogenic provinces, belts and sub-belts,and main mineralizing elements, principle mineralizing epochs, major tectonic units, and main mineral occurrences information of metallogenic belts and sub-belts. Furthermore, this dataset provides basic geological information for trans-boundary correlative researches of metallogenesis between China and Russia, Mongolia, and North Korea bilaterally. Meanwhile, it can also guide geological researches and mineral resources exploration in the SNA.

Abstract:The Comparative Study of Tectonic Environment and Metallogenic Laws of Cu-Au Mineralization in the Indo-China Peninsula and Western Pacific Giant metallogenic belt takes the Indo-China Peninsula and the giant Western Pacific metallogenic belt as the study area and targets Cu and Au minerals. Data was systematically collected via international cooperation based on the compilation of 1:1, 500, 000 scale Geological and Mineral Map of Indo-China Peninsula and Western Pacific Giant metallogenic belt, Southeast Asia. Study results were deepened and maps in English and Chinese versions were published after studying the metallogenic environment, ore-controlling factors and metallogenic laws of typical deposits in the study area covering Laos, Thailand, Burma, Papua New Guinea, etc. and combining them with ETM+, Hyperion and ASTER multi-source remote sensing images. Cu-Au deposits mainly in Laos were analyzed, while prospecting demonstration and drilling verification were conducted in the Aven deposit area, Laos. The study achieved positive prospecting effects. Moreover, using MapGIS and ArcGIS technical platforms, maps of metallogenic laws of mineralization zones/regions were compiled, and quantitative evaluation models for different minerals and a spatial dataset of Au-Cu deposits in significant metallogenic zones/regions in Southeast Asia were developed. In addition, using the mathematical modeling method, resource potential assessment was conducted for the study area, and mineralization prospects for different minerals were delineated within the study area. This dataset is not only a summary of mineral resource zoning and resource potential assessment, but also a theoretical basis for scientifically guiding China's prospecting deployment in other countries (the Belt and Road Initiative).

Abstract:The dataset of zircon geochronological testing of the Qingyuan Complex in Northern Liaoning Province gets its information from the rock testing and analysis activities under the financial support of the project ‘Global Correlation of Asian's Neoarchean Strata’, which is actually based on the program ‘Compilation of Asian Serial Geological Maps and Research of Related Major Geological Thematic Issues’. The zircon chronological data can precisely reflect the protolith's genetic epochs and their subsequently experienced tectonic-magmatic events. The lithogeochemical data can reflect the chemical features of the rocks themselves. The combination of the above two types of data can provide scientific evidences and basic data support for the study of the crustal evolution in the Northern Liaoning Province. This paper has analyzed the rock samples from the mid-to-high grade metamorphic supracrustal rocks and the tonalitic-trondhjemitic-granodioritic gneiss (TTG gneiss) units in the Qingyuan Complex in Northern Liaoning Province; their rock types include:gneissoid granodiorite, tonalitic gneiss, trondhjemitic gneiss, granodioritic migmatitic gneiss, diopside-amphibolitic leptynite, amphibolitic biotite plagioclase gneiss, gneissoid charnockitic granite, garnet charnockite biotite plagioclase gneiss, granitic gneiss, amphibolitic diopside biotite plagioclase gneiss, metamorphic intermediate volcanic rocks, biotite plagioclase gneiss, plagioclase amphibolite, and sillimanite garnet gneiss. This dataset is of Excel format tables, including 2.xls type files (Zircon_U-Pb dating data_QY.xls, Geochemistry data_QY.xls), which have respectively recorded the zircon U-Pb dating data and the geochemical data of the samples. All the testing process is finished by National Geological Experiment & Testing Center of China with the results being highly reliable.

Abstract:In order to accurately find out the needs of users of geologic data and eliminate the information gap between data users and data managers, the National Geological Archives of China (NGAC) has conducted the data collection of user's accessing logs to the master station of the Digital Geological Library of NGAC. The automatic recording method is applied to register the user's location, their searching keywords, IP address and other related information for constructing the accessing log dataset. In order to make better use of these accessing data, a standardized processing method and quality control system are adopted. The dataset provides the accessing records to the Digital Geological Library of NGAC's master station from the year 2014 to 2017, which realistically reflects user's behaving habits while obtaining geological data. It also provides a sound basis for the further constructions of geological data service website, the development and utilization of geological data, and the geological data management and services.

Abstract:Situated in China's Three Gorges Reservoir Region, the Fengjie County is prone to frequent geo-hazards. This area features big topographic relief, well-developed structures and soft rocks, and relatively fragile geological environment. This paper employs field geological surveys to ascertain the distribution regularities of geo-hazards and geo-hazard breeding geological setting in the studied area.
