Characteristics of Soil Geochemistry and Its Prospecting Significance in Liemen Area, Jinchuan County, Sichuan

Abstract

Liemen area is located in Late Triassic Markam-Jinchuan super-large-scale lithium polymetallic ore-forming area in western Sichuan, where many middle-scale and super-large-scale granite pegmatite-type lithium ore deposits have been found and polymetallic conditions are Favorable. Based on a 1:10000 soil geochemistry survey, the characteristics of six elements closely related to the mineralization of rare metals were analyzed, and the variation coefficient and enrichment coefficient of the elements were calculated. It is found that Li is the main ore-forming element. On this basis, the single element anomaly and 5 synthetic anomalies are delineated. Five lithium ore bodies were found in the anomaly investigation, which provided the basis for further exploration.
