Geological characteristics and prospecting direction of Sanjiaoding gold mine in Saishiteng area

Abstract This article studies the geological characteristics analysis and prospecting direction of the triangle top gold mine in the Saishiteng area, so as to realize accurate and massive gold mining in this area in the future. Taking the triangle top area of Saishiteng area located in the northern margin of Qaidam Basin from Saishiteng Mountain to Tanjianshan Mountain as the research object, the technical route of combining field investigation with indoor comprehensive research is adopted, and the observation of field geological characteristics is emphasized, and the geophysical characteristics are analyzed, and finally the characteristics of regional geological structure are obtained. The controlled source audio-frequency magnetotelluric method is used in combination with geological characteristics, and the distribution of gold deposits in the study area is determined by calculating and detecting electromagnetic anomalies, and the prospecting direction of gold deposits is clear. The test results show that the stratum structure in the study area is rich, the folds and faults are very complex, the primary colors of metals are distributed in all strata, and the elements of Au are more distributed. According to the results of electromagnetic analysis, there are magnetic anomalies in M15 and M18-1 areas, and these two prospecting target areas are clearly identified through detection.
