金伯利岩物化探找矿模式及其远景区预测

GEOPHYSICAL AND GEOCHEMICAL PROSPECTING MODEL OF KIMBERLITE AND PREDICATION OF PROSPECTIVE AREAS

摘要:

通过对山东蒙阴地区金伯利岩管、岩带的地质、地球物理与地球化学特征及其背景场的分析，建立了该区金伯利岩物化探找矿模式，并应用该找矿模式对鲁西地区４１０００ｋｍ２范围进行了金伯利岩成矿远景区预测。对所选出的远景预测区，又用层次分析法经排序筛选出８处金伯利岩远景区，其中Ａ类远景区３处、Ｂ类远景区４处、Ｃ类远景区１处。

Abstract:

Based on the analysis of geological, Geophysical and geochemical characteristics of kimber lite pipes and belts and its background in Mengyin region,Shandong Province,a geophysical and geochemicsl prospecting model is estsblished, which has been applied in the predication of prospective areas for diamond within 4100km2 in western Shandong. The predicted prospective areas are then put in order according to rank analysis and 8 kimberlite prospective areas are selected. Among them, 3 are of A grade, 4 are of B...
