物化探方法在“焦家式”金矿普查中的应用

APPLICATION OF GEOPHYSICO-GEOCHEMICAL METHODS IN RECONNAISSANCE SURVEY OF THE JIAOJIA TYPED GOLD DEPOSITS

摘要:

本文在简述胶东地区“焦家式”金矿地质条件的基础上,较详尽地列举了典型矿区的岩、矿石地球物理参数和地球化学元素分布特征以及在区域地球物理场和典型矿体上的物化探异常规律和特点,并就多年的找矿实践,总结出了寻找“焦家式”金矿的地球物理和地球化学模式,提出了区分矿与非矿异常的方法。并阐述了在金矿普,详查和勘探各个阶段中,如何充分发挥物化探方法的作用,以及各方法的工作配合程序。

Abstract:

Preceded with a brief account of the geological conditions of the Jiao bei-typed gold deposits in Jiaodong Area, the authors present the geo physical parameters and the distribution patterns of geochemical elements related to the rocks and ores in the typical gold mines in detail. They alsoexplicate the patterns and features of the regional geophysical fields and of the geophysical and geochemical anomalies on the typical ore bodies. A geophysico-geochemical model for exploring the Jiaojia-typed gold deposi...
