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.
