胶东上庄金矿床深部找矿信息综合研究

Study on Comprehensive Ore-Prospecting Information in the Deep Part of Shangzhuang Gold Deposit in Jiaodong Area

近年来,深部找矿研究已成为矿产勘查学中备受关注的研究课题之一。受目前矿产勘查理论与技术水平的限制,深部找矿工作中有效找矿信息难获取、难识别,并且所获取信息可靠性低、多解性强;由于深部矿化特征与浅部矿化特征又往往存在较大的差异,致使浅部有效的找矿信息难以直接运用于深部矿的探测中。这些因素导致目前深部找矿工作的不确定性强,风险性大。通过对上庄金矿床的地质信息(包括:控矿断裂构造信息、控矿岩浆岩信息)、矿化信息(包括:矿物学信息、围岩蚀变信息、地球化学信息、地球物理信息)等方面的综合研究,并将有关成果应用于上庄金矿床的深部找矿工作中,发现了焦家带Ⅰ号矿体,取得了显著的找矿效果。

In recent years,deep deposit exploration receives much concern in the research field of metallogeny and mineral exploration.Limited by the theory and technical level of mineral exploration,effective prospecting information is difficult to obtain and distinguish in the deep deposit exploration,and the information obtained is low reliability and multi solvability.Because there is a big difference between shallow and deep mineralization,prospecting information in shallow part is difficult to be directly applied to the detection of deep ore bodies.These factors have led to strong uncertainty and risks in deep exploration.Based on comprehensive study of geological information（including ore-controlling fault structure information,ore-controlling information of magmatic rocks）and mineralization information of Shangzhuang gold deposit（including mineralogy information,wall-rock alteration information,geochemical and geophysical information）,the achievements have been applied in deep prospecting of Shangzhuang gold deposit,Jiaojia Ⅰore body has been found,and a significant prospecting effect has been gained as well.
