The present continental block of South China went through at least three stages of tectonic development: geosynclinal, platform and diwa (the latter mean ing mobile region of post-platform stage). In the process of geotectonic evolution, two types of tectono-metallogenic provinces have developed: One with thinner crust (30-35 km) and mantle uplifting, and the other with thicker crust (35-39 km) and mantle subsiding. The author compares the metallogenic evolution of the above two provinces, describing the role of deep-seated fracture zones and comparing the geochemistry of the granitoid rocks of each of the provinces, including the isotopic composition and the abundance of the rare earth elements.
