张川县陈家庙铁矿地质特征及矿床成因分析

摘要

本文通过对陈家庙铁矿的地层、构造、岩浆活动、矿体特征及围岩蚀变等地质特征分析，认为陈家庙铁矿严格受地层控制，其成矿作用与构造和岩浆活动无显著成因联系，该矿床形成于早古生代的同沉积作用时期，经过后期的区域变质作用的改造，形成沉积变质型铁矿床。%The geological characteristics of Chenjiamiao iron deposit ,such as the ore stratum, structure, magmatic activi-ty, host-rock alteration etc .were analyzed and it is believed that the iron ore bodies are strictly controlled by the lower Pale -ozoic strata, and the iron mineralization has no significant genetic relationship with tectonic and magmatic activity .The met-allogenesis is closely related to the early sedimentary and the late regional metamorphism .
