2、yofGeosciences，Beijing100083，China摘要：照島山金礦位于膠東牟平一乳山成礦帶北段，礦體產(chǎn)于中生代燕山期昆崳山二長花崗巖中，主要受NNE向金牛山斷裂帶的控制。對金的成礦背景、礦床地質(zhì)、控礦因素和礦體隱伏特征的研究結(jié)果表明：圍巖蝕變從近礦到遠(yuǎn)礦依次發(fā)育黃鐵絹英巖化、絹英巖化和鉀長石化；金的成礦分為黃鐵礦石英、石英黃鐵礦、多金屬硫化物、石英碳酸鹽礦物4個階段：昆崳山巖體和荊山群變質(zhì)巖的接觸帶附近易于成礦；金牛山主斷裂走向NE的拐折地段、不同期次斷裂交會處和多期斷裂破碎帶部位都易于成礦；金品位高值區(qū)呈近似等距分布，32線以南有向
3、SW側(cè)伏的趨勢，40線以北有向NE側(cè)伏的趨勢。總結(jié)了照島山金礦的控礦因素。初步推測了深部找礦方向關(guān)鍵詞：金礦；熱液蝕變；成礦階段；控礦因素；膠東照島山中圖分類號：P618．41；P614文獻(xiàn)標(biāo)志碼：A文章編號：1671—2552(2010)06—0933—12ZhangYQ，LiSR，ChenHY，XueJL，SunWY，ZhangX．Identifyingofalterationmineralizationphaseandanalysisonore—controllingfactorsofZhaodaoshangolddeposit,Muping，e
