【摘要】 辽宁宽甸大西岔乡庙沟硼矿赋存于下元古界辽河群含硼变粒岩层位。通过对矿床的研究认为在褶皱构造翼部蛇纹石化镁橄岩的厚大部位,蛇纹石化、金云母化、透闪石化强烈地段,有利于赋存有工业价值的硼矿体。此外,相伴的磁异常应在找矿工作中引起重视。更多还原

【Abstract】 The Miaogou boron deposit occurs in granulitite of Liaohe group,lower proterozoic erathem,locating at Daxicha village,Kuandian town,Liaoning. The research of the deposit shows that,at the tip of fold structure, where the violent serpentinizaion,phlogopitization,tremolitization and with thick serpentinization for sterite, make for the host of commerical value boron orebody,in addition,the concomitant magnetic anomally should be pay more attention in ore-searching.更多还原
