Abstract:The East Kunlun Orogen is a giant magmatic tectonic activity belt and an important part of the Central Orogenic Belt of China. It has superior mineralization conditions and remarkable mineralization phenomena, and has always attracted the attention of some geologists. The Lalangmai Tungsten Mine is located in the Chahanwusu River area in the eastern section of the East Kunlun Orogen and is under the jurisdiction of Huishui township, Dulan county, Qinghai province. It is a newly discovered skarn-type deposit in recent years. This article takes the Lalangmai tungsten deposit as the research target. Purpose: The purpose of the research is to establish a geological-geochemical exploration model to guide the deployment of prospecting for the tungsten deposit in the Lalangmai area. Method: The research method was selected based on the comprehensive analysis of the mineralization geological background, the geological characteristics of the mining areas, and the characteristics of the surface soil geochemical anomalies, and further summarized the geological-geochemical prospecting mark, thereby constructing a geological-geochemical exploration model. Result: The main conclusions obtained from the research include: W-Sn-Mo-Au-Ag-As-Sb elements have a strong correlation, while other elements have a poor correlation. The currently discovered tungsten ore bodies (mineralized bodies) mainly occur in skarn rocks. The contact zone between tonalite diorite and Baishahe formation strata is the most favorable location for finding tungsten ore. The northeast-southwest trending structural fracture zone is an ore-containing structure. The metal minerals in the tungsten ore bodies are mainly scheelite, followed by wolframite. Conclusion: Based on the geological-geochemical exploration model constructed in the article, 3 prospecting target areas were delineated in the Lalangmai area, including 1 Class-I prospecting target area and 2 Class-II prospecting target areas. In addition, it is expected that the deep areas and the peripheral areas of the mining area have great prospecting potential. More geological exploration work arrangements should be implemented. The innovation of this article is the systematically constructed geological-geochemical exploration model, which has achieved good prospecting results in the Lalangmai tungsten mining area and achieved a breakthrough in prospecting for tungsten deposits in the eastern section of East Kunlun Orogen, and has provided a new prospecting and exploration path for searching for the same type of tungsten deposits in the area.
