青海省哈日扎地区1∶2.5万地球化学测量有效性分析
|
摘要
地球化学成矿元素的确定是建立典型矿床地球化学找矿模型的主要内容。哈日扎铜多金属矿是在东昆仑成矿带发现的中型矿产之一,并建立了以矿化带为单元的成矿元素组合特征。但是因近年来全区内未开展大比例尺化探工作,对全区成矿元素组合特征未做系统的分析。基于区内2016年开展的1∶2.5万地球化学测量工作,采用浓幅分位法确定成矿元素的方法,对比分析1∶2.5万地球化学测量和1∶5万水系沉积物测量在哈日扎地区的优劣,进而说明1∶2.5万地球化学测量在该区的有效性。
Determination of geochemical ore forming elements is the main content of establishing geochemical prospecting models for typical deposits.The Harzha copper polymetallic deposit is one of the medium-size minerals discovered in the eastern Kunlun metallogenic belt,and a metallogenic element assemblage characteristic with mineralization belt as unit is established.However,in recent years,large-scale geochemical exploration has not been carried out in the whole area,and no systematic analysis has been made on the characteristics of ore forming elements in the whole area.Based on the 1∶25 thousand geochemistry survey carried out in 2016 in the region,the method of determining the metallogenic element by the concentrated separation method is adopted,and the advantages and disadvantages of the 1∶25 thousand geochemical survey and the1∶50 thousand water system sediment measurement in Harzha area are compared and analyzed,and the effectiveness of the geochemical measurements of 1∶25 thousand in this area is illustrated.
