摘要
为进一步探索庐枞盆地南缘铅锌银矿床成因,对枞阳县城山陶家巷铅锌矿床成矿模式进行分析。依据矿床类型及前期勘查成果对矿床的成矿地质背景、地球化学特征、成矿地质特征等进行梳理,分析矿床形成条件。经研究发现,区内侏罗系磨山组、三叠系拉犁尖组为主要赋矿地层,北东向构造破碎带为矿床含矿热液主要通道,城山岩体及晚期闪长玢岩为区内成矿提供含矿热液流体。
In order to further explore the genesis of the lead-zinc-silver deposit in the southern margin of the Luzong Basin,the metallogenic model of the Taojiaxiang lead-zinc deposit in Chengshan,Zongyang County was analyzed.According to the deposit type and previous exploration results,the metallogenic geological background,geochemical characteristics and metallogenic geological characteristics of the deposit are sorted out,and the formation conditions of the deposit are analyzed.It is found that the Jurassic Moshan Formation and Triassic Larijian Formation in the study area are the main ore-bearing strata,the NE-trending structural fracture zone is the main channel of ore-bearing hydrothermal fluid,and the Chengshan rock mass and late diorite porphyrite provide ore-bearing hydrothermal fluid for mineralization in the area.
