莱芜市铁铜沟金铜铁矿地质特征及其成因探讨

Study on Geological Characteristics and Origin of Tietonggou n Gold Bearing Copper-Iron Deposit in Laiwu City

摘要:

莱芜市铁铜沟含金铜铁矿床产于中生代燕山期靳家桥角闪闪长玢岩与奥陶纪马家沟群五阳山段石灰岩的接触带，矿体形态严格受接触带控制。通过对矿区内地层、控矿构造、侵入岩、矿体特征和矿石质量的分析论述，认为该矿床为接触交代高温热液型含金铜磁铁矿矿床。

Abstract:

Tietonggou gold-bearing iron copper deposit in Laiwu city occurred in the contact part of Jinjiaqiao diorite porphyrite in Mesozoic Yanshan period and limestone of Wuyangshan section in Ordovician Majiagou group. The shape of ore bodies is strictly controlled by contact zone. Through analysis on strata, ore controlling structures, intrusive rocks, characteristics of ore bodies and ore quality in mining area, it is regarded that this deposit belongs to contact metasomatic high temperature hydrothermal type gold bearing copper magnetite deposit.
