沂水县高庄地区铜铅矿地质特征及成矿模式探讨

Study on Geological Characteristics and Metallogenic Model of Copper Lead Deposit in Gaozhuang Area of Yishui County

摘要:

沂水县高庄铜铅矿赋存于张夏组盘车沟段灰绿色页岩夹薄层泥灰岩和张夏组下灰岩段鲕粒灰岩之间的构造角砾岩中，在形态上和空间位置上严格受蚀变角砾岩带控制的似层状矿体。通过对矿区内地层、控矿构造、矿体特征和矿石质量的分析论述，认为该矿床为碳酸盐型中低温热液充填—交代矿床，并建立了成矿模式。

Abstract:

Gaozhuang copper lead deposit in Yishui county occurred in tectonic breccia between graygreen shale with thin marl of Panchegou section and oolitic limestone of lower limestone section in Zhangxia group. It is bedded type deposit which are strictly controlled by the alteration breccia zone on the shape and spatial position. Through analysis and discussion on strata, ore structures, ore characteristics and ore quality in this area, it is considered that this deposit is a carbonate type low-medium thermal filling deposit. The metallogenic model is established as well.
