Analysis of geological and mineral characteristics and prospecting prospect in Liudaogou area, Laji mountain, Qinghai Province

The study area is located in the eastern part of the South Qilian active belt of the Central Orogenic Belt, in the north of Hualong block and the southeast edge of the middle Qilian block. Except that the upper Paleozoic Carboniferous system is not exposed, the quaternary system from Lower Proterozoic to Cenozoic is fully developed, and folds and faults are relatively developed. The area is located in the middle of the Caledonian iron, nickel, cobalt, gold, rare earth and phosphorus metallogenic belt in Lajishan. The geological structure is relatively complex and the metallogenic conditions are good. By carrying out geological, geophysical and geochemical survey, trenching, drilling and sample analysis in this area, the geological, structural, magmatic rock, geophysical and geochemical characteristics of this area are analyzed, and the distribution characteristics of ore bearing strata, structures and mineralized bodies in this area are found out. The ore body controlled by the project in this area is delineated, the resource is estimated, and the prospecting prospect of this area is analyzed.
