摘要:
青海都兰沟里金矿整装勘查区1：100 000地质矿产数据集由系统库、建造构造图、地质矿产图、地磁ΔT平面等值线图、地磁ΔT化极平面等值线图、化探综合异常图、矿产预测成果图及附表组成；每张图文件夹内有对应的编图说明。沟里整装勘查区总体被新元古代-早古生代东昆中缝合带（Pt3-P2末）、中-晚古生代兴海-苦海缝合带（D-P3）、晚古生代-早中生代（C-T2末）阿尼玛卿缝合带分割为4个二级构造单元。区内岩浆活动以奥陶纪-泥盆纪和二叠纪-三叠纪为主，分别代表了两期不同的造山旋回，成矿期可能在晚三叠世-早侏罗世。此次工作在整装勘查区内共圈定了1：50 000磁异常21处、化探综合异常80处；划分4个三级成矿带（区）、7个四级成矿亚带、8个五级矿带（矿田）、17个六级有利找矿区块；在有利找矿区块中筛选并提交找矿靶区14处；通过后续投入，区内相继发现了那更康切尔大型银矿、德龙金矿、迈龙金矿点、浪木日铜镍矿点、龙什更铜钴矿点等一批有找矿潜力的矿床（点）；估算区内金资源总量588.04吨、银资源总量3 197.85吨、铅-锌资源总量235.83万吨，铜-钴资源总量121.49万吨。
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.
