Streamsediment geochemistry and prospecting prospect in Dachebeigou area of Jilin Province
摘要
Abstract
The Dachebeigou area of Jilin Province is located in the southern margin of eastern Xing'an-Mongolia orogenic belt,geochemically belonging to Changbai Mountain forest swamp landscape area.There are 76 mineral deposits such as Erdaodianzi Au deposit,Xingfu Sb deposit and Piaohechuan Cu-Ni deposit discovered in and around the study area,with good prospecting prospect.The correlations,enrichment-depletion characteristics and combination features of elements,as well as the prospecting potential of major elements,are ascertained based on the content data of 17 elements by the 1:50 000 stream sediment survey.Combined with regional geological background and 1:200 000 stream sediment survey data,it is considered that Au,Cu,Ni and Sb are the main metallogenic elements,and their geochemical anomalies are well-matched.According to the metallogenic conditions of the area,25 comprehensive anomaly areas and 2 prospecting prospective areas are delineated,which provides basis for further prospecting work.关键词
