Geochemical Characteristics And Prospecting Direction Of Hutoushanbei Area, Ejinaqi,Inner Mongolia

Based on a systematical description of regional geological setting and the ore-forming geological features of Hutoushanbei,Ejinaqi,Inner Mongolia,the paper has made further study on the 1:50000 geochemical characteristics,and abnormal distribution and characteristics of 1:50000 stream sediment in this area.The favorable ore-forming geological conditions in this area have been generally analysed.Besides,the paper has conducted analysis of and study on the typical deposits of ZhusilengHaierhan copper-gold deposit and Hulunxibai gold deposits and regional ore-forming rules.Geochemical anomaly shows Au,Cu,As,Sb indicator elements such As obvious enrichment,in Hutoushanbei area,especially in the Au,Cu,Sb clearly show that the area has formed copper,gold,ore deposit geochemical conditions.In the stream sediments in Hutoushanbei area,it is enriched in elements of Au,Cu,As,Sb,especially in Au,Cu,Sb and Ba.The area is with good geochemical conditions for the formation of copper,gold,antimony and other deposits.For the rocks in Hutoushanbei area,they are enriched in elements of Au,Sb,Pb,W,As,Ni,Zn,Mo,Hg,Cu,and Ag in varying degrees.They are characterized by the enrichment of Ba,Pb,Mo,As,Au,Ag,etc.especially of Ba,As,Sb and Au,which reflects the geochemical characteristics of being enriched in general trace elements and good conditions for ore-forming in the area.The element supergene enrichment patterns in Htoushanbei are : Ba and Au,Sb,Pb,W,As,Ni,Zn,Mo,Hg,Cu,Ag and other elements have experienced supergene enrichment in varying degrees;the adopted stream sediment survey method,which can effectively rule out the influence of aeolian sand,has been verified in thearea,objectively reflecting the geochemical characteristics of this area.
