山东省稀有金属矿产资源特征及找矿方向浅析

Study on Characteristics of Rare Metal Mineral Resources and the Prospecting Direction in Shandong Province

稀有金属在现代高新技术和国防建设中具有重要用途,属于国家战略性矿产。山东省已发现多个稀有金属矿床(点),主要分布在威海、青岛、泰安、枣庄等地区。山东省内稀有金属矿床按其成因主要分为滨海沉积型、花岗伟晶岩型以及滨海澙湖沉积型3种稀有金属矿床。本文总结了山东省稀有金属矿产勘查及开发利用现状和供需形势,论述了3种成因类型典型稀有矿床的地质特征,划分了找矿远景区并提出了相应工作手段,为今后稀有金属矿产勘查提供参考。

Rare metals have important uses in modern high-tech and national defense construction.They are national strategic minerals.Several rare metal deposits(spots)have been found in Shandong province.They are mainly distributed in Weihai,Qingdao,Tai'an,Zaozhuang and other areas.According to the origin,rare metal deposits are divided into three types,they are coastal sedimentary rare metal placer deposits,granite pegmatite rare metal deposits,and coastal lagoon sedimentary rare metal deposits.In this paper,current situation of the exploration,development and utilization and the supply and demand situation of rare metal minerals in Shandong province have been summarized,and geological characteristics of typical deposits of three genetic types have been discussed,different prospecting areas have been divided,and corresponding working methods have been put forward.It will provide some references for the exploration of rare metal minerals.
