里冲区段地质勘查特征与找矿标志

Geological Prospecting Features and Prospecting Indicators in Lichong Section

分析里冲区段地质勘查特征,根据预查阶段物探工作获得的4处磁异常分布特性,通过地表地质测量及槽探控制的方法,分析里冲区段地质勘查的特征以及热接触变质作用特性,根据交代变质作用分析和热接触变质作用分析联合特征分析的方法,得出找矿的标志位主要发生于勘查区西部,呈带状分布于花岗岩体边缘。根据区内地层、构造、岩浆的分布情况及特征分析,实现里冲区段地质勘查特征与找矿标志量化分析。

Analyze the characteristics of the geological survey in the Lichong section.According to the four magnetic anomaly distribution characteristics obtained from the geophysical prospecting work in the pre-investigation stage,the characteristics of geological exploration and thermal contact metamorphism in Lichong section are analyzed by means of surface geological survey and trough exploration control.According to the combined feature analysis method of metasomatic metamorphism analysis and thermal contact metamorphism analysis,it is concluded that the landmarks for prospecting mainly occur in the western part of the exploration area and are distributed in bands.On the edge of the granite body.According to the analysis of the distribution and characteristics of the strata,structure and magma in the area,the quantitative analysis of the geological exploration characteristics and prospecting signs of the Lichong section is realized.
