摘要
张家堡子绿泥石矿床赋存于辽河群盖县组绿泥石片岩中,共划分8个矿体,矿体呈脉状,顺层产出。矿石呈鳞片变晶结构,块状构造,主要矿物成分为绿泥石,含量90%以上;矿石化学成分特征为低硅、高镁、高铝;经分析认为矿床成因类型属中—低温区域变质热液交代矿床。
Zhangjiapuzi chlorite deposit occurs in chlorite schist of Gaixian formation of Liaohe group,and is divided into 8 orebodies,the orebody is veined and produced along the bed.The ore is of scaly crystalline structure and massive structure,the main mineral composition is chlorite,the content of more than 90%.The chemical composition of the ore is low silicon,high magnesium and high aluminum.According to the analysis,the genetic type of the deposit belongs to the medium-low temperature regional metamorphic hydrothermal metasomatic deposit.
