Geochemical Characteristics of Stream Sediments in the Nenjiang-Heihe Area,Heilongjiang Province and the Metallogenic Prognosis
摘要
Abstract
The Nenjiang-Heihe area includes the famous Duobaoshan ore concentration area in Heilongjiang Province.This area contains abundant mineral resources dominated by gold,silver and copper,and the recent discovery of a large number of deposits indicates a great metallogenic prospect of this area.This study area belongs to a forest swamp landscape area.In order to better realize prospecting breakthrough in this area,this work collected original data from 1∶200,000 and 1∶250,000 stream sediment measurements,and processed and analyzed the data to determine geochemical parameter characteristics of elements,associations of elements and their regional distribution.A total of 1259 single element anomalies were delineated,including 114 gold anomalies,88 copper anomalies,64 silver anomalies,and 112 combination anomalies.The characteristics of various elements were comprehensively studied,and the distribution of element anomalies was analyzed according to the anomalies of stream sediments.Combined with typical ore deposits,three prospecting areas were delineated,i.e.,the NE-trending gold and silver prospective area from Fabielaxishan to Changqing village,the Duobaoshan gold-silver-copper prospective area,and NS-trending silver prospective area from Team No.2 of Guli farm to Daziyangshan fire prevention inspection station.These three prospective areas can provide basis for discovering gold,silver,copper resources in this area.The characteristics of the combination anomalies No.Hs-51 and Hs-38 were evaluated,and a total of six large deposits have been discovered so far,including the Sandaowanzi gold deposit,Zhengguang gold deposit,and Tongshan copper deposit,indicative of a still significant mineralization potential in the region.关键词
