Abstract:
The reef carbonate rocks of well Xike-1 are analyzed for mineral compositions to explore the development process of reef and paleo-ocean environmental changes. It is found that carbonate minerals in the core of well Xike-1 are mainly composed of calc...

Abstract:
There are two pending key problems in research on western boundary faults (WBF) of South China Sea (SCS). One is itself structural-geometric linkage of the WBF of the SCS, that is whether there is a united dynamic boundary along the WBF of the SCS. T...
