    摘要:

    内蒙古东部的黄岗-甘珠尔庙矿带是地处大兴安岭南段的锡乡金属矿带。矿带中各矿床的磁铁矿、锡石、方铅矿、闪锌矿的主元素和微量元素数据表明,这些矿床是属与燕山期岩浆活动有关的矽卡岩型、热液型、斑岩型和云英岩型矿床;其成矿金属组分中的铁来源于区域晚古生代海相中-基性火山岩,部分铅锌来源于区域二叠纪地槽沉积物。研究还表明,与燕山期偏碱性花岗岩有关的锡钨矿床和与燕山期中酸性花岗岩类有关的铅锌矿床其方铅矿、闪锌矿的微量元素含量及比值存在明显的差别。

    Abstract:

    The Huanggang-Ganzhuermiao ore belt of east Inner Mongolia is tin- polymetallic ore belt i.n Southern Da Hinggan Mountains. Data of major and minor elements in magnetite, cassiterite, galena and sphalerite from ore deposits within this ore belt suggest that these ore deposits are of skarn, hydrothermal, porphyry and grei.sen types related to Yanshanian magmatic activity and that iron in ores came from regional Permian marine interme- diate-basic volcanic rocks whereas partial lead and zinc from Permian geo- syncli顶c sediments. Studies also indicate that galena and Sphalerite in tungsten-tin deposits related to Yanshanian subalkaline granite diffei obt}i- ously from these minerals in lead-zinc deposits associated with Ya}zsha}lian intermediate-acid granitoids i.n contents and ratios of minor elements.
