Global tectonic facies: a preclusive opinion

At the beginning, the analysis of tectonic facies of collision orogenic belts is a method to divide Alps orogenic belt into a number of tectonic units and to compare them with those in China. It is a pure problem of methodology without any obscure theory. Based on the research of Chinese orogenic system, the author added some new contents which are not included in Alps orogenic belt, and 6 facies and 15 sub-facies are proposed. Geo-tectonic facies section and plain map are obtained on this basis. The analysis of global tectonic facies is more than just collision belt, which should include the geodynamic settings and processes. Therefore, the key elements in the classification of globle tectonic facies are dynamics, geodynamic settings and structured lithology assemblage. 4 types of geo-tectonic environment, 11 sub-environment and 31 geo-tectonic facies are proposed in this paper.
