摘要: 本文概略地介绍了分散岩石样品的元素点异常概率统计方法,并以1:5万地质填图为例,探讨了该方法的区域含矿性评价、化探异常Ⅲ检查等方面的应用。研究认为:Ⅰ号铜异常主要由次火山岩引起民,并与已知次火山岩型铜矿点的元素组合特征相似,主要成矿元素是全区点异常概率较高的元素,优选出四个找矿预测靶区,初步确认了S3-D1W地层的旧属。岩层点概率元素组合较了反映了岩层形成时的和形成后所经历的地质作用,成矿作用和构造特征。

Abstract: Brief descriptions are made for the probability analysis of point anomalies of various elements from dispersed rock samples and for the application of this method to the evalutation of regional prospects and geochemical anomalies. It is suggested that copper anomaly no.1 is induced by sub-volcanic rocks and has similar element association to the known copper mineralizations genetically related to sub-volcanic intrusions. The major economic elements have relatively higher point anomaly probabilities. Four target areas for prospecting have been located. The stratigraphic position of the clastic sediments of the Utubrak Group has been defined. Element association resultant from probability analysis of point anomalies is indicative for the geologic, tectonic and mineralization events suffered by the strata during and after their formation.
