摘要
备战铁矿是西天山阿吾拉勒铁矿成矿带成因类型典型成矿条件较好的具有代表性的铁矿区.文章通过对备战铁矿矿石化学成分、矿石的微量元素特征、矽卡岩REE特征等一系列矿床相关的地球化学特征的研究,进一步说明备战铁矿床的磁铁矿成因类型不单是火山沉积型,还有与热液改造相关的矽卡岩型,矽卡岩成岩物质来源于深源岩浆,同时也有壳源物质的混染,具有壳幔混合的特点.
Beizhan iron ores is the representative metallogenic region with typical genetic type and good metallogenic conditions in the Awulale iron belt. Through the research of the iron ore chemical composition, ore of trace elements characteristics, skarn REE characteristics and so on a series of skarn deposits the geochemical characteristics of the research in this article , the type of cause of Beizhan magnetic iron ores is not only related of volcanic sedimentary type but also skarn type concerned with hydrothermal modification. The diagenetic material of skarn, with the feature of mixture of the crust and mantle, comes from deep source magma and the shell source material mix dye.
