基于GIS的矿区多元信息集成在南秦岭池沟斑岩体矿化蚀变和找矿预测中的应用

The Application of Integration of Multiple Information in Mining Area Based on GIS in Mineralized Alteration and Prospecting Prediction in ChiGou Pluton, Southern Qinling Mountains

池沟铜钼矿床为南秦岭地区近年来新发现的一斑岩型铜钼矿床,利用GIS平台上的SURPAC软件提取池沟矿床的地、物、化原始数据建立了空间数据库、矿体模型、岩体模型、断层模型、以及物化探数据模型。进一步研究分析池沟矿区成矿地质模型和I、II、III、IV、V号岩体的空间形态辅助判断了岩体、矿体及断层构造三者之间的关系,依地质体趋势指导、并进行找矿预测,提出了验证工程布设部位,为进一步的研究、勘查工作指明了方向。

The ChiGou Cu-Mo deposit is a newly discovered porphyry-type Cu-Mo deposit which belongs to south Qinling area in recent years. This paper utilizes the SURPAC software on the GIS platform to collect the original data of geology, geophysical exploration and geochemical exploration, setting the spatial database, ore body model, body model, fault model and geophysical with geochemical data model. Further study is conducted to analyze the mineralization geological model and the spatial patterns of rock masses I, II, III, IV and V in the ChiGou mining area. Moreover, it helps determine the relationship among the rock mass, ore body and fault structure, goes into the prospecting forecast, and the layout of the project site is put forward, which provides the direction for further research and exploration work.
