胶东破碎带蚀变岩型金矿地质－地球物理找矿模型

GEOLOGIC-GEOPHYSICAL PROSPECTING MODEL FoR THE GOLD DEPOSITS OF CRUSH-ZONE-ALTERED&ROCK TYPE IN JIAODONG(EASTERN SHANDONG)

摘要:

本文通过对胶东西部岩矿石物性参数的分析，结合已知矿床地质特征，首先建立了金矿体及不同围岩的单一物性模型。在对已知金矿实测的物理场特征进行概括的基础上，按不同的赋矿围岩，建立了破碎带蚀变岩型金矿的地质—地球物理找矿模型。该模型具有类比性和外推性，对在胶东西部应用物探方法间接寻找破碎带蚀变型金矿，具有一定的借鉴意义。

Abstract:

First a simple model for the physical properties of the country rocks of the gold deposits in Jiaodong was established based on the an al ysis of the data of t he pr opert ies of r ock s and ores in the western Jiaodong regiou and combined with the geologic features of the gold deposits. Then,a geologic-geophysical prospecting model for the gold deposits of crush-zone-altered-rocktype hosted in various country rocks is established on the basis of generalization(summarization)of the measured properties of ge...
