2、應(yīng)等特征,提取了五龍金礦黃鐵礦中重要的成因和找礦信息。首次利用黃鐵礦微量元素的三角形圖解對礦區(qū)深部遠(yuǎn)景及其外圍靶區(qū)內(nèi)礦脈的礦化遠(yuǎn)景進行了預(yù)測,不僅為五龍金礦的成因研究提供了可信的礦物學(xué)依據(jù),而且對五龍礦區(qū)深部及其外圍靶區(qū)內(nèi)礦脈的礦化遠(yuǎn)景進行了有效的評價,認(rèn)為五龍金礦系中一淺成巖漿熱液成因的金礦床,礦區(qū)深部及其外圍的220號脈、38號脈、2號脈的金礦化遠(yuǎn)景較佳。關(guān)鍵詞:標(biāo)型特征;黃鐵礦;石英脈型金礦;五龍礦區(qū);遼寧中圖分類號:P57;P618.51文獻(xiàn)標(biāo)識碼:A文章編號:1000—8527(2005)02—0231一o8StudyofPyriteTypomorphicCharac
