Deep Survey and Synthetical Study of the South China Continent |
The South China continent located on the southeast margin of the Eurasia plate is an active continental margin, which is characteristiced by the crustal and obvious lateral uncontinuation。 As the continent-ocean trasition zone the South China continent is also the active tectonics zone ofearth’s core-mantle material transmission and the obvious area of the mantle migrating and mantleplume growing as well as global act-catastrophism, The green stone occurring on the South Chinacontinent was formed from 2000Ma to 1000Ma and its geochemical composition shows a progres-sive evolution tendency i.e. from original mantle to depted mantle to enricher mantle. Gravity sub-sidence and hot point volcanism is controlled by the ultra-mantle plume and inplate continental mar-gin breakup belt. |
