芳山水泥配料用砂岩矿位于江苏省南京市溧水区与常州市溧阳市交界处,赋存于上志留统茅山组(S3m)和上泥盆统五通组(D3w),共划分 3 个矿体,分别位于芳山倒转背斜南东翼和北西翼,矿体构造形态中等,层状产出,总体呈北东—南西向,倾向南东,整体连续性较好.矿石自然类型为石英砂岩,工业类型为水泥配料类硅质原料.初步认为该矿矿床类型为机械沉积型,陆源碎屑建造相沉积成因类型.
Geological Characteristics and Genesis of Fangshan Sandstone Deposit for Cement Batching in Changzhou,Jiangsu Province
The Fangshan sandstone deposit for cement batching is located at the junction of Lishui District,Nanjing city,and Liyang,Changzhou city,Jiangsu province.It occurs in the Upper Silurian Maoshan formation(S3m)and the Upper Devonian Wutong formation(D3w).It is divided into three ore bodies,located in the southeast wing and northwest wing of Fangshan inverted anticline respectively.The structural form of the ore body is moderate,with layered output.The overall direction is northeast-southwest and inclined towards southeast,with good overall continuity.The natural type of ore is quartz sandstone,and the industrial type is cement based siliceous raw materials.It is preliminarily considered that the deposit type is mechanical deposition type,and continental clastic tectonic facies sedimentary genetic type.
