重磁放综合物探方法在鲁西微山稀土矿勘查中的应用
Research on the application of the integrated gravity-magnetic-radioactive geophysical exploration method in the exploration of rare earth deposit in Weishan,western Shandong
摘要
Abstract
Since the periphery of the Xishan rare earth deposit in Weishan County,western Shandong is mostly covered by the Quater-nary strata,single geophysical exploration methods are ineffective in searching for rare earth elements in this area.To establish a geo-logical-geophysical prospecting model for deep rare earth prospecting in this area,a combination of exploration techniques and methods suitable for the deep exploration of rare earth deposits in this area were selected through multiple geophysical exploration technology ex-periments on the known geological profiles.The distribution range of the underground Mesozoic Xishan alkaline complex was roughly determined through gravity survey and high-precision magnetic survey.The ore body outcrop was delineated through ground-based gam-ma spectrometry,and the deep ore body characteristics were revealed through drilling.Finally,this study developed an integrated geo-physical exploration method including gravity-magnetic joint delineation of rock masses,radioactive positioning for ore body outcrops,and deep drilling.By using this exploration model,one super-large rare earth deposit was discovered in this area,providing a reference for the exploration of rare earth deposits in the surrounding area.关键词
