Time Domain Induced Polarization Method For Gold-ore Prospecting In Qinghai Yeluotuo Quan Area

Yeluotuo Quan gold-ore is located in the Qinling Qilianshan Kunlunshan lateCaledonian orogenic system, Serteng mountain aercituoshan orogenic belt, northernmargin of Qaidam paraplatform relict mountain fault fold belt Xisaishen Teng Shansynclinorium south. Through comprehensive analysis of wild camel spring areadistribution of geochemical anomalies, found that Au, Co elements is high in the abnormalvalue of this area, the Au, Co and other high temperature elements in the study area hugemetallogenic potential, the geological data has been made in the study area reflect, Au, Comainly occur in limonite quartz porphyry and limonitization quartz rock. These two typesof rock exists in the alteration zone. But the study area of eolian sand is covered by a thick,the surface is only exposed phyllite, therefore find alteration zone is the focus work. In thegeological means limited circumstances, which has played an important role in the area tohighlight the geophysical prospecting. Induced polarization method provides direction andthe basis for the future geological work.In the study area, induced polarization method through time domain, solve theconstraints due to geographical and geological conditions, geological and geochemicalmethods can not solve the geophysical prospecting. Using the geophysical method,successfully delineated a vein of gold, and the occurrence of orebody, trend. To provide afavorable basis for subsequent drilling verification, finally presented the larger gold,cobalt mine a.According to the "Qinghai Province Yeluotuo Quan gold, cobalt pre check" project,based on analyzing the special geographical conditions on the wild camel spring area andgeological background, difference through alteration zone type gold deposits are lithology,by geophysical methods summarization of metallogenic regularities, prospecting target,guide the prospecting, has important theoretical and practical significance. This papermade the following main results and understanding.1. The wild camel spring Au domain induced polarization method in time forgold-ore prospecting method research, achieved good results.2. Through the study of rock electrical differences within the region, the electricalmethods are favorable to mineralization anomalies by. 3.Tsing the method of penetrating strong, the exploration depth of coverage area ofQuaternary deposit characteristics were studied, discussed the ore prospecting method forconcealed area.On the mining area through geophysical methods for searching the occurrence of oreblock Au, Co ore body are analyzed. Through a year of work, combining with thegeophysical and geological data, through analysis and research, the delineation of8concealed orebody (alteration), provides a strong basis for the study area prospectingwork.
