On the complex and mixed collision zones in China Continent;

The late Archean collision orogenic belt in Wutaishan is situated in the central part of the North China Plate.

Because a collision orogenic belt has a complicated crustal structure, new methods have to be adopted for thermal state analysis.

It is suggested in the paper that the Neoarchean collision orogeny in Wutai Mountain is with the character of oceanic crust subduction and continental-continental collision based on synthetic study of the slices, such as tectonic lithological combin.

The Wutaishan collision orogen may be divided into three tectonic slices by applying the tectonic lithologic event method;from south to north they are the forearc mélange zone,paleoisland arc system and backarc mélange zone.

On the basis of geological studies of some 28 localities of Ultrahigh-Pressure Metamorphic (UHPM) rocks all over the world it is not difficult to find that most UHPM belts are developed in close relationship with the island arc-continent and the continent-continent collisional orogenic belts.

In a collisional orogenic belt,the strength of crust-mantle interaction is also positively correlated with metallogeny;especially in a multi-stage collisional orogenic belt,crust-mantle interaction was stronger and the belt contains abundant mineral resources.
