摘要
甘肃崖湾-大桥地区金锑矿整装勘查区1∶50 000矿产资源潜力评价数据集包括:综合建造构造图、成矿要素图、预测要素图、预测成果图等。应用最新资料,对区内建造构造进行梳理。以金、锑矿为主要矿种,重点以"三位一体"找矿预测理论为基础,完成大桥金矿、坪定金矿、崖湾锑矿的研究,划分其成因类型、预测类型,总结区域成矿规律,建立区域预测模型,圈定最小预测区42个,金矿预测资源量560 774.59 kg,锑矿预测资源量737 241.43 t。数据集的建立反映了整装勘查区1∶50 000矿产资源潜力评价的示范性成果,总结探索出其研究思路、工作方法、工作流程、预期成果及成果表达等内容,对该类型潜力评价工作具有一定的参考意义。
The dataset of 1∶50 000 mineral resource potential assessment of the goldantimony deposit integrated exploration area in Yawan-Daqiao Area, Gansu Province(also referred to as the Dataset) includes comprehensive suite-structure maps, metallogenic factor maps, predictive factor maps, prediction result maps, among others. During the development of the Dataset, the suites and structures in the integrated exploration area were collated using the latest data. Meanwhile, focusing on gold and antimony deposits, the Daqiao gold deposit,Pingding gold deposit, and Yawan antimony deposit in the integrated exploration area were studied based on the "trinity" prospecting prediction theory of exploration areas that integrates metallogenic geological bodies, metallogenic structures, metallogenic structural planes, and metallogenic characteristics and indicators. As a result, the genetic types and predication types were classified, the regional metallogenic regularity was summarized, and the regional predication models were established. Furthermore, 42 predicted minimum prospecting target areas were delineated, with predicted gold and antimony resources of 560 774.59 kg and737 241.43 tonnes, respectively. The development of the Dataset provides a demonstration of1∶50 000 mineral resource potential assessment of integrated exploration areas. Meanwhile,relevant research ideas, working methods and processes, expected results, and result presentence were summarized and explored. Therefore, this Dataset will provide certain references for similar potential assessment.
