This book analyzes and studies a large number of geological data in the world by dividing the world into eight types of tectonic systems for the first time. It then puts forward the evolution characteristics of each structural system. It also discusses the main controlling factors of the formation of structural systems, and points out that there was no regional metamorphism in the global Paleozoic and some areas of the meso Neoproterozoic. These innovative theoretical understandings not only fill in gap of knowledge in the established global tectonic system, but also enrich and develop the theory of global geological science.
