华北地台北缘三个硫-多金属成矿带中几个远景区的资源预测

RESOURCE PREDICTION OF THE PROSPECTS IN THE METALLOGENIC BELTS OF THE NORTH MARGIN OF NORTH CHINA PLATFORM

通过对华北地台北缘狼山-渣尔泰、燕辽及林西一带三个硫-多金属成矿带的资源远景评价,采用"欧氏距离相似系数法"进行了资源潜力预测。分别圈定出:三贵口、白音布拉沟尤阁庙、小并沟A级远景区,对门山哈沙图庙、南公中、欧布乞B级远景区;沙窝店、杨树沟A级远景区,黄土梁、梓木林、赵家村、峪尔崖B级远景区;雅马吐、敖尔盖-阿德勒根山、昭胡都格、驼峰山A级远景区,代铜山、好来宝B级远景区。在三个区中选择三贵口、沙窝店、羊山砬子、驼峰山、昭胡都格等几处(多金属)硫铁矿进行了具体评价,证实了该区具有较大的找矿潜力。

Resource perspective of the three metallogenic belts-Langshan-zhaertai, yanliao, linxi-tianshan,in the north margin of North China Platform,is estimated. The resource potential is predicted by way of ＂Euclidean distance similarity coefficient＂and prospects are determined.In Langshan-zhaertai metallogenic belt, there are prospects of Sanguikou. Baiyinbulagouyougemiao , Xiaojingou at A grade, prospects of Duimenshanhashatumiao. Nangongzhong. Oubuqi at B grade： in yanliao metallogenic belt, there are prospects of Shawodian, Yangshugou at Agrade, Huangtuliang. Zimulin. Zhaojiacun. Yuerya at B grade： in linxi-tianshan metallogenic belt, there are prospects of Ymatu, Aoergai-Aletugenshan. Zhaohudouge, Tuofengshan at A grade, Daitongshan, Haolaibao at B grade. Sanguikou. Shawodian. Yangshanlazi, Tuofengshan, Zhaohudouge troilite deposits are selected to be estimate concretely, it is approved that the area has prospecting potential.
