辽宁大獾子岭铁矿地质特征与找矿标志分析

The Analysis of Geological Characteristics and Indictors of Prospecting the Dahuanziling Iron Deposit in Liaoning

通过对辽宁大獾子岭铁矿床成矿地质背景条件、矿床地质特征及蚀变矿物组合的分析研究,得出大獾子岭铁矿为火山沉积-变质铁矿床,矿体主要赋存于辽河群里尔峪组,严格受层位控制。绿泥石化、碳酸盐化及金云母化等蚀变矿物组合是其主要的找矿标志,结合地球物理和地球化学异常,指出了该区地质-地球物理-地球化学找矿方向,实现区域深边部找矿突破。

We can conclusion that Dahuanziling iron deposit is volcano - sedimentary - metamor- phic iron deposit according to analyse the geological background, Geological characteristics of the deposit and altered mineral of the pyrite deposit . Orebody mainly Occurs in Lieryu formation of Li- aohe group, and strictly controlled by the horizon. Combining altered mineral assemblage such as chloritization, carbonatation, phlogopitization with geophysical and geochemical atypical features which are indictors to prospect the ore in order to achieve the break when we prospect ore in the deep areas.
