山东省沂水县北躲庄矿区处于汞丹山凸起之上，其西侧为马站苏村凹陷，东侧为莒县凹陷。区域地层分布较齐全，构造复杂，岩浆岩发育。该矿区地层简单，只出露新太古代泰山岩群柳杭组地层包体和新生代第四纪松散堆积物；构造有韧性剪切带和脆性断裂构造2种；岩浆岩发育，主要分布有古元古代条花峪单元、松山单元、三官寨单元。铁矿体赋存于泰山岩群柳杭组的顶部，共圈定了7个矿体，矿体呈层状产出，倾向110°～120°，倾角47°～82°。TFe 品位29％～37％。其矿体成因为沉积变质型铁矿。

Beiduozhuang iron deposit in Yishui county of Shandong province locates in Gongdanshan uplift.Its west part is Masu -Sucun depression,while its east part is Juxian depression.Distribution of regional strata is com-plete,structures are complex and magmatic rocks develope well.Strata in this area are simple,only exposed inclu-sions in Liuhang formation of Neoarchean Taishan rock group and Cenozoic Quaternary loose sediments.Structures can be divided into ductile shear zone and brittle fault structure.Magmatic rocks developed well and mainly distrib-uted in Paleoproterozoic Tiaohuayu unit,Songshan unit and Sanguanzhai unit.
