THE APPLICATION OF HYDROCARBON DETERMINATION METHOD TO THE PROSPECTING POTENTIAL EVALUATION OF THE BAIYUN GOLD DEPOSIT IN LIAONING

The authors systematically collected samples from the surface of the 11 prospecting lines above Ⅰ-1 ore body and from different elevations in theⅠ-1 ore body within the Baiyun gold deposit,Liaoning Province. Analysis of the correspondence between the spatial distribution of the abnormal indexes and the ore body was conducted so as to reveal the relationship between the secondary halos and primary halos. It is found that the hydrocarbon technique can be used in this area. In this paper,the authors summarized the geological and geochemical prospecting criteria of this area. By analyzing the hydrocarbon components and the abnormal distribution of some trace elements in northern Yaojialing together with the geological conditions of the abnormal areas,the authors made a comprehensive evaluation of prospecting potential and delineated the prospective areas.
