鲁西胡家庄——西石马地区稀土矿成矿地质特征及找矿前景分析

Metallogenic Geological Characteristics and Prospecting Prospect of Rare Earth Elements Deposits in HujiazhuangXishima Area in Western Shandong Province

摘要:

鲁西胡家庄—西石马地区是山东省重要的稀土矿找矿远景区,区内构造活动强烈，与稀土成矿有关的中生代碳酸岩发育，有明显的γ能谱异常和La、Y等地球化学异常。该区已发现稀土矿点3个，矿体25个，矿化体和各种找矿线索众多，并已圈定3个B级找矿靶区，找矿前景较好，找矿潜力较大。本文对区内成矿地质背景、地球物理特征、矿体特征、矿石质量、围岩蚀变等进行了分析，总结了该地区稀土找矿标志、矿床成因，对找矿前景进行了分析，为今后该地区稀土矿勘查提供借鉴作用。

Abstract:

HujiazhuangXishima area located in westerm Shandong province is an important rare earth element(REE)prospecting prospective area with strong tectonic activity. Mesozoic carbonatite rocks that related to REE mineralization developed widely .γ energy spectrum and La,Y geochemical anomaly is obvious. Three REE ore sites, 25 orebodies, mineralized bodies and various prospecting clues have been found in this area. Three Bgrade prospecting targets have been delineated. Therefore, this area is a good prospecting prospect and great potential prospecting area. Based on the analysis of metallogenic geological background, geophysical characteristics, orebody characteristics, ore quality and wall rock alteration, REE prospecting signs and the origin of the deposit have been summarized, and the ore prospecting prospect in this area has been analyzed. It will provide some references for prospecting of REE mineral resources in this area in the future.
