摘要
荣成市大疃刘家铍矿床赋存于中生代正长花岗岩中,受北西向张扭性断裂控制。铍元素以羟硅铍石单矿物赋存于绢云母化高岭土化正长花岗岩中,其次呈分散状态分布于绢云母中。矿床的形成与富碱性热液和钙碱性正长花岗岩有关,为中温热液型铍矿床,形成于中生代燕山晚期。
Datuanliujia beryllium deposit in Rongcheng city occurs in Mesozoic syenogranite which is controlled by tension and contorted fault with the trend of NW. Beryllium element occurs in sericitization-- kaolinization syenogranite as bertrandite single ore, and distributes in sericite as seperated type occurrence. Ore--forming has close relation with rich--alkalescence geotherm and calc alkali syeogranite, which belongs to middle temperature geothermal beryllium deposit, and formed in Mesozoic Yanshan period.
