3、變質(zhì)型、榴輝(閃)巖型和機(jī)械.沉積型三種類型。同時從地層、構(gòu)造以及成礦地質(zhì)條件等方面簡要探討了礦床(點(diǎn))的成礦規(guī)律和控礦因素,在此基礎(chǔ)上識別出地層時代、巖性、地球化學(xué)異常等找礦標(biāo)志,并初步勾勒出湖北棗陽.河南新縣以及湖北英山.安徽潛山兩個金紅石礦床的找礦遠(yuǎn)景區(qū)。本文對成礦區(qū)金紅石礦成礦規(guī)律的總結(jié)和成礦條件的分析顯示出成礦帶金紅石具有極大的找礦潛力,可望成為我國最具潛力的金紅石戰(zhàn)略儲備基地。關(guān)鍵詞:成礦規(guī)律;控礦條件;找礦前景;金紅石礦床;武當(dāng)一桐柏一大別成礦帶中圖分類法:P617;P618.47
