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。
通過對遼寧大獾子嶺鐵礦床成礦地質揹景條件、礦床地質特徵及蝕變礦物組閤的分析研究,得齣大獾子嶺鐵礦為火山沉積-變質鐵礦床,礦體主要賦存于遼河群裏爾峪組,嚴格受層位控製。綠泥石化、碳痠鹽化及金雲母化等蝕變礦物組閤是其主要的找礦標誌,結閤地毬物理和地毬化學異常,指齣瞭該區地質-地毬物理-地毬化學找礦方嚮,實現區域深邊部找礦突破。

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.
