In an effort to reconcile different data sources (seafloor spreading, seismic and gravity images, well calibrations, outcrop studies) in the South China Sea (SCS), we reviewed unconformity records, particular context with shut-off of seafloor spreading SCS. With respect start there is a consensus: ca. 34-41 Ma. Recent infer end near magnetic Anomaly 5 = 15.5 Ma (Langhian age). Northwest Borneo,...

Late Precambrian to early Cambrian sediments of the Amadeus Basin, Central Australia, contain two stable directions of magnetization. Lithologies are diverse and include red beds, green beds, and carbonates, all of which respond to thermal cleaning. Positive fold and unconformity tests, and a well-defined polarity zonation reveal the primary component and direction of magnetization. This direct...

The Eocene to Lower Oligocene deposits of the Penyu and Malay basins are formed by fluvial-lacustrine with marine influence in latter. sequence consists mainly siltstone, several intercalations fine-grained sand volcanic tuff. Based on well data, Mid-Upper sediments exist Basin deeper parts half grabens sub-basins. Hence, this implies age basin initiation at Mid-Eocene, rather than as tradition...
