| 摘 要： | 沉积变质型铁矿是山东省鲁西地区重要成因类型之一,含矿层位为新太古代泰山岩群。经过地表工程和钻探工程验证,瓦泉寨矿区C1、C2、C3、C5磁异常是由铁矿体引起。矿体总体走向NW,倾向NE,倾角55°~88°,厚度1.44~6.29m;主要矿物为磁铁矿;矿石主要呈粒状变晶结构、条带状构造。同时,本文对沉积变质型铁矿床的成因进行了分析,铁质来源与基性火山活动关系密切。

| Abstract: | Sedimentary metamorphic iron ore is one of the important genesis types in western Shandong and its ore-bearing horizon locates in Neoarchean Taishan Group.The surface and drilling engineering verifies that magnetic anomalies of C1 , C2 ,C3 and C5 in Waquanzhai ore area are induced by iron ore-bodies.The general trend of the ore-body is along NW and its dip direction is along NE.Its inclination angle is 55°~ 88°and its thickness is 1.44 ~ 6.29m.The main mineral is magnetite with granoblastic and banded structure.This pa-per analyzed the genesis of sedimentary metamorphic iron deposit,and it is suggested that the iron origin is closely related to basic volcanic activity. |
