山东省蒙阴县常马矿区金刚石原生矿深部综合找矿模型

Comprehensive Prospecting Mode of Primary Diamond Deposit in Deep Changma Area in Mengyin County of Shandong Province

摘要:

以矿区地质背景、含矿岩体地质特征为基础，分析了蒙阴县常马矿区金刚石原生矿的成矿地质条件，提出含矿岩体是受构造控制的金伯利岩岩体，岩体具有低电阻、低负重力场的地球物理异常等信息。在综合分析矿床成矿地质条件、磁异常、电性异常特征的基础上，初步建立了蒙阴县常马矿区金刚石原生矿矿床地质－磁法－电法综合找矿模型。

Abstract:

Based on geological characteristics of orebearing rocks and geological background, geological condition of diamond primary ore of Changma mining area in Mengyin county has been analyzed. It is regarded that orebearing rock is kimberley rock controled by structures, and rock is geophysical anomalies with low resistance and low negative gravity. On the basis of comprehensive analysis of oreforming geological conditions, characteristics of magnetic anomalies and electrical anomalies, geologicalmagneticelectric integrated prospecting model of diamond primary ore in Changma mining area of Mengyin county has been established primarily.
