内蒙古苏尼特左旗巴彦洪格尔地区土壤测量地球化学异常特征及找矿方向

Geochemical anomaly characteristics in soil survey of Bayanhonggeer area in Sonid Zuoqi of Inner Mongolia and its prospecting direction

文章在1∶5万土壤地球化学测量成果基础上,对内蒙古苏尼特左旗巴彦洪格尔地区的地球化学参数进行计算和分析,对区内元素分布特征、元素相关性及组合特点、主要综合异常特征进行了研究,结果表明:区内Ag、Pb、Sn、W含量较高,分异性又强,所形成异常规模较大,强度较高,具有较大找矿价值。结合对主要综合异常的分析,划分出古尔班呼都格金、银找矿远景区,苏吉敖包钨、铅、锌找矿远景区,哈尔德勒铅、锌找矿远景区,查干诺尔钼找矿远景区。

On the basis of pedogeochemical survey at scale of 1∶50000,this paper calculated and analyzed the geochemical parameters of Bayanhonggeer area in Sonid Zuoqi of Inner Mongolia and studied on the distribu-tion features of elements,relevance and combination features of elements and characteristics of primary com-posite anomalies in the area.The results suggested that:contents of Ag,Pb,Sn and W were relatively high with strong differentiation,and the scale of the resulting anomalies was relatively large with high intensity. The prospecting potential was great.Combined with analysis on primary composite anomalies,the author di-vided the area into prospective regions including Guerbanhuduge Au-Ag prospective area,Sujiaobao W-Pb-Zn prospective area,Haerdele Pb-Zn prospective area as well as Chagannuoer Mo prospective area.
