| Summary: | accommodation space overlying the tilted fault blocks; age given to the magnetic anomalies of the southwest subbasin an intrusive, axial zone on strike with the southwest and Pigott (1986), who concluded that the South China Sea Basement (66.5 Ma), were identified and mapped within the Nam basin initially opened in the southwest during the by Taylor and Hayes (1980, 1983) and more recently by Briais channelization of the transparent sequence followed by the compression: deposition of a transparent sequence during a Conson basin using 2700 km of migrated, multifold, seismic Cretaceous. The two periods of NW-SE extension found in the deposition of another sedimentary sequence. Apparent Miocene et al. (1993). This study throws doubt on the model of Ru extension produced additional extensive NE-SW striking normal extrusion model proposed by Tapponnier et al. (1982, 1986). extrusion of the Indochina microplate and synchronous, left faulting, formation of half grabens, and the emplacement of Identification of several additional unconformities in the is an asymmetric, extensional basin. It formed as a result lateral motion at the terminus of the Mekong fault caused the Middle Miocene. This rapid southwest propagation was movement and the Middle Miocene seanoor spreading of the Nam Conson basin created by the Oligocene left-lateral fault Nam Conson basin. In the Early Miocene, NW-SE seafloor of Oligocene and then Middle Miocene, NW-SE extension. The Oligocene extension that formed the initial structure of the period of quiescence and thermal subsidence; and probably due in part to a NE-SW zone of weakness caused by propagated southwestward reaching the Nam Conson basin in the reflection data. The results show that the Nam Conson basin seismic data show how the Nam Conson basin developed after southwest subbasin support some components of the collision spreading in the South China Sea southwest subbasin rapidly subbasin spreading center.These results confirm the Miocene the Middle Miocene, through the subsequent infilling of the Oligocene extension. The resulting, Middle Miocene to Recent volcanoes were also identified along 1090 E. Two major unconformities, Middle Miocene (15.5 Ma) and Top of |
