摘要

太行山南段是我國極具成礦潛力的地區(qū)之一。摩天嶺地區(qū)石英二長斑巖是該區(qū)域主要巖石類型之一，其地球化學(xué)特征及成因機(jī)制的研究對于區(qū)域成礦作用的探討和礦產(chǎn)資源潛力的挖掘具有重要意義。本文通過野外地質(zhì)調(diào)查、顯微鏡觀察、巖石薄片分析和巖石地球化學(xué)分析等手段，研究了摩天嶺地區(qū)石英二長斑巖的礦物組成、地球化學(xué)特征、成因機(jī)制等方面，并對其成礦作用做了初步探討。結(jié)果顯示，摩天嶺地區(qū)石英二長斑巖屬于過鋁質(zhì)系列，具有高鋁、富堿、富鐵、貧鈣等特征。與其相似的巖石常見于大規(guī)模巖漿拆離過程中，推測該巖石形成于特殊地質(zhì)背景下，受到廣泛的混染和部分熔融，形成了巖漿系列，具有一定的成礦潛力。
