A Study of Ore-Controlling Factors and Metallogenic Mechanism of Lead-Zinc Deposit in Luziyuan, Zhenkang, Yunnan

Abstract:

The lead-zinc ore in Luziyuan, Zhenkang Town, Yunnan Province is a large lead-zinc polymetallic deposit discovered in recent years. The ore body mainly occurs in the stratum of Shahechang Group of Upper Cambrian. Controlled by NE trending faults and its flanking associated structures, it features equal interval and lateral trending distribution in the spatial domain. The development and mineralization of wall-rock alteration experienced two stages, low medium temperature stage and medium-high temperature stage. Metallogenic materials are mainly from the ore-bearing stratum and deep concealed rock mass. Through the study of such geological features as lithology of ore-bearing stratum, structure of ore-controlling Faults, wall-rock alteration, and ore fabrics, the author believes that the formation of the deposit is closely related to the multi stages of tectonic movements and magmatic hydrothermal activities. It is a sedimentary-reworked type, and skarn-type lead-zinc-iron polymetallic deposit and it is of multiple mineralization stages and varieties of mineral sources.
