The genetic type of iron and copper deposit of Daye-type skarn pattern is the most famous one of all the genetic type of iron and copper deposit in the world.

Geological characteristics and genesis of Xianghualing skarn type tin deposit;

The lead-zinc ores can be classified into the hydrothermal vein type and the skarn type with strong wall rock alteration.

Namuchuo-Jiali fracture zone is a polymetallic ore zone where copper, lead and zinc ores are the main types of ores and skarn type ore deposit is the typical ore deposit species.

The Tonglushan copper-iron deposit,being one of contact metasomatic skarn polymeatal deposit,is at medium risk for use up of its resource after 30 years mining.

One type is skarn-type, and the other is interbeddedsulfide type.

Based on analysing metallogenetic geological characteristics of the Chenfang copper-polymetallic deposit,this paper systematically studies the distribution features of skarn-type copper,lead and zinc polymetallic orebodies controlled by contact zones in the Carboniferous strata and by interformational fracture zone.

This article based on the study of the region mineralization geological background of the region, the geological characteristics of the ore body, the ore-controlling factors and the analysis of ore deposit origin, obtains four kinds of mineralization type in the mining area: skarn-type of contact strip, skarn-type which controlled by the level crush.
