摘要
本文总结了毛坪铅锌矿床产出的区域地质背景、地层、构造、岩浆岩等条件和矿床地质特征,提出该矿床严格受构造和岩性控制,是在区域构造驱动下,深源流体与盆地流体发生大规模运移和混合的结果;该矿床与典型MVT型铅锌矿床在成矿地质背景、矿石矿物组合、围岩及蚀变等方面有较大相似性,但在矿体产状、矿石品位、构造控制等方面又有区别,可能是一种特殊的MVT矿床。
This paper summarizes the geological characteristics of the deposit includes conditions and regional geological setting of Maoping Pb-Zn deposit, Stratum, structure, magmatic rocks, point that the deposit is controlled strictly by structure and lithology, Driven by the regional, large-scale Deep basin fluid and Basin fluids migration and mixing; the typical MVT Pb-Zn deposits are Similar with Maoping Pb-Zn Deposit in geological setting, ore mineral assemblage, rock and alteration, etc., but in the orebody, ore grade, controlled by structure and other asnects are different .it mav be a special kind of MVT Pb-Zn denosits.
