A Consideration about the Development of Ocean Plate Geology |
| |
| Abstract: | In order to reveal the material composition and the structure of the orogenic belt, we propose the ocean plate geology, which is used to explain the process of continental formation and evolution and the source of dynamics. Based on the theory of plate tectonics and geological research methods, the subduction-accretionary complex, the ophiolite belt, and other oceanic lithospheric plate geological formations and structure construction in the orogenic belt are systematically studied in order to find the igneous rock association of the front arc in the subduction zone. In the initial subduction process of the ocean plate, the magmatism from the forearc basalts (FAB) to the boninite, high-Mg andesite (HMA), to the arc tholeiite and calc-alkaline lava and its different stage evolution, are studied in order to identify the characteristics of the original arc and front arc igneous rock association, which reveals the ocean-continent transition in the evolution process from ocean basin to the continent, laying a scientific foundation for the establishment and development of ocean plate geology. |
