TYPICAL TECTONIC STYLES AND THEIR GEOLOGIC SIGNIFICANCE IN EASTERN GUIZHOU PROVINCE
-
Abstract
The Mesoproterozoic-Neoproterozoic to Cenozoic strata, including many types of magmatite and metamorphite, are developed in eastern Guizhou Province.Multi-periods of tectonic movements happening in the study region have been divided into Wuling structural cycle, Caledonian tectonic cycle, Yanshan tectonic cycle and Himalayan tectonic cycle.Typical structural styles are Alpine fold, Jura-type fold, thrust-nappe structure, ductile shear zone, metamorphic core complexes, extension-stripped fault system, strike-slip fault system, horst-graben structure, respectively.Difference of tectonic styles in different tectonic periods reflects the difference of structural positions.Therefore, in the plane, the Jiangnan orogenic belt is a composite orogenic belt composed of different orogenic sub-belts with evolution history of eastward migration.
