汤山金矿是江苏省发现的唯一一个小型微细浸染型独立金矿床。基于汤山金矿区1∶20万、1∶5万自然重砂建库数据,结合矿床矿石矿物组合特征,选择褐铁矿、黄铁矿、砷矿物(雄黄、雌黄、毒砂)、辰砂、自然银、铅矿物(自然铅、方铅矿、白铅矿)、闪锌矿、自然金、铜矿物(黄铜矿、斑铜矿、蓝铜矿、孔雀石)、重晶石等作为主要标型矿物,通过ZSAPS2.0软件,应用GIS平台,圈定自然重砂组合异常。通过异常特征剖析发现,黄铁矿和褐铁矿为汤山金矿直接指示矿物,自然金、闪锌矿、辰砂、毒砂、重晶石为汤山金矿次一级指示矿物。在此基础上,结合地质找矿标志,建立汤山金矿地质—自然重砂找矿标志,为深入评价汤山金矿找矿潜力提供自然重砂方面的依据。
Tangshan Gold Mine is the only small fine disseminated gold deposit discovered in Jiangsu Province. Based on the data of 1: 200000, 1: 50000 natural heavy sand building in Tangshan gold mining area and combining with the characteristics of ore mineral assemblage, we selected limonite, pyrite, arsenic minerals (realgar, reticulata, arsenopyrite) Natural Silver, Lead Minerals (Natural Lead, Galena, Lead), Sphalerite, Natural Gold, Copper Minerals (Chalcopyrite, Bornite, Azurite, Malachite), Barite etc. The main standard mineral, through ZSAPS2.0 software, application of GIS platform, delineated a combination of natural sand abnormalities. According to the analysis of the anomalous characteristics, pyrite and limonite are the direct indicator mineral of Tangshan gold deposit, natural gold, sphalerite, cinnabar, arsenopyrite and barite as the secondary indicator mineral of Tangshan gold deposit. On the basis of this, combined with geological prospecting signs, the prospecting symbol of geological-natural heavy sand of Tangshan gold deposit is established, which provides the basis for further evaluation of the prospecting potential of Tangshan gold deposit.
