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.
