广西全州小源铅锌矿地质特征、成因类型及找矿方向探讨

Geological characteristics of Xiaoyuan Pb-Zn deposit and discussion of the genesis and prospecting directions

小源铅锌矿床是桂东北地区海洋山NE向铅锌铜成矿带中段的一个小型矿床。区内的中上奥陶统田岭口组上段和下泥盆统莲花山组是主要含矿地层;矿脉产于NE走向的张扭性正断层(断裂)中,构成多条平行等距排列的矿脉带;区内发现含矿脉带5条,圈定矿体7个;矿体在脉带中分布具有等距性。矿床成因类型为以岩浆热液为主的多源复合断裂控制热液脉型矿床。小源地区是寻找大型铅锌矿床有利地段。

Xiaoyuan Pb-Zn deposit is a small deposit in middle of NE Haiyangshan Pb-Zn-Cu ore belt.At the deposit Upper member of Middle-Upper Ordovician Series and Lianhuashan formation of Lower Devonian Series are the main ore-bearing strata.Ore veins occur in NE tensional normal faults arranging in parallel and equal-distant vein zones.In all there are five such zones in which 7 ore bodies are delineated.Ore bodies in the zones are also distributed in equal distance.This is a hydrothermal-dominant multi-sources deposit controlled by complex fault.Xiaoyuan area is potential for prospecting large size Pb-Zn deposit.
