辽宁砖庙硼矿地质特征及成矿作用
GEOLOGIC FEATURES AND IT’S MINERALIZATION OF ZHUANMIAO BORON DEPOSIT IN LIAONING
【摘要】 砖庙硼矿为产在辽吉裂谷带的硼镁石矿床。矿层赋存于早元古界辽河群里尔峪组含硼变粒岩段。共分7个矿段。矿体多分布在大理岩膨大部位,并随其同步膨缩和等间距尖灭再现。根据赋矿层位、容矿岩石特征、矿石结构构造及B2O3品位进行混合筛分成果、数学地质判别资料综合分析表明,火山活动为硼矿形成提供物质来源,矿床形成经历沉积及变质改造二个阶段。
【Abstract】 Zhuanmiao boron deposit is a szaibelyite deposit which is located in Liaoning-Jilin rift zone. The ore bed hosts in boracic granulite of Lieryu formation,Liaohe group of lower proterozoic. There are seven ore blocks in this district,with the orebody mostly distributed in swelled marble,synchronously following it iuflation and contraction,as well as its isorange thining out and reproductivity. According to the sieving results of host rock features,ore texture,and grade of B2O3,it is shown by the comprehensive analysis of mathematic geology information,that volcanic activity provided the substance source and the boron deposit information went through the sedimentary process and the stage of metamorphic and alteration.
