The lead and zinc polymetallic deposit in LuziYuan is an ultra-large type skarn deposit. The ore body originated from the interlayer crushed zone between the second and thrid section of stratum marble and slate (schist) interbedding of upper Cambrian series Shahechang group, the wall rock alteration is intensice in the diggings, and the alteration zoning is obvious. Through field geological investigation and data analysis, based on the petrography of alterated rocks and combined with catalog information of drilling, the wall rock alteration in the diggings of LuziYuan is divided into four alteration zones,which are in sequence: carbonate-quartz-chloritization zone; carbonate-quartz-skarn lithification zone; skarn-lead zinc ore mineralization zone; and skarn-pyritization zone. The forming of ore body is related to alterations such as skarn lithification, silicification, marmarization, magnetite, etc.

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.

Sanbao silver polymetallic deposit is overally located in the front of "North convex" in Laojun Mountain granite body, belonging to polymetallic deposit of stratabounded medium-low temperature hydrothermal reformation genesis. It has been found that six mineralized belt, having developed the wall-rock alteration. The prospecting criterion is determined by ore genesis and ore-controlling factor.

With continuous consumption of proven resources, people have to turn to new resources or find new ways for prospecting. As to Yunnan Gejiu Tin and copper polymetallic deposit, deep ore prospecting may be the solution. The newly discovered copper-polymetallic deposit inside the rock of Tangzi’ao depression zone, which located in western part of Yunnan Gejiu east tin mine area, is a new type of deposit in deep ore prospecting. This kind of deposit produced in the alkali-rich, oxidizing environment, potash feldspathization is an important sign of prospecting, and a variety of metallic elements can be comprehensive utilization. It is special that potash feldspathization zone and epidotization zone alternating with each other; the phenomenon may caused by multi-period of hydrothermal fluids. By quantitative calculating the results of altered rocks and original rock samples, the author find out the migration laws of the constant elements and the main ore-forming elements and their associated elements, which provide a basis for prospecting in the future.
