The rift section of the Brazilian basins represent sedimentary record associated with first stages Gondwana break-up in Early Cretaceous phase (Berriasian to Aptian). succession Campos Basin constitutes one main petroleum systems Brazil’s marginal basins. This interval contains source rock and important reservoirs Lagoa Feia Group deposits. is characterized by siliciclastic, carbonate evaporite...

Abstract The seismic stratigraphy and sedimentary facies of the Cretaceous Paleogene successions in north-eastern offshore part Taranaki Basin, New Zealand have been investigated order to unravel their depositional evolution identify potential hydrocarbon plays. Interpretation regional lines covering entire shelf-slope deepwater regions as well integrating allows identification several seismic-...

The Global Stratotype Section and Point for the newly defined Ediacaran System has been ratified at the base of the cap carbonate in Enorama Creek. A near-continuous section from the Marinoan glaciation to the base of the Cambrian is exposed in the Flinders Ranges, with type sections of included stratigraphic units exposed in the area around Brachina and Bunyeroo gorges. The stratigraphy and lo...

Performance based seismic design (PBSD) is a cogent design approach that allows engineers to design structures with a predictable seismic performance for a specified level of hazard. In contrast to the conventional limit state or strength and serviceability based design in which a structure is designed to withstand severe load combinations and be functional under normal load conditions, PBSD go...

Seismic anisotropy is an efficient way to investigate the deformation field within the upper mantle. In the framework of rigid tectonic plates, we make use of recent tomographic models of azimuthal anisotropy for deriving the best rotation pole of the Pacific plate in the uppermost 200km of the mantle. It is found to be in good agreement with current plate motion (NUVEL1, HS3 and NNR). However,...

This paper reports on the damage of Wushi bridge in a recent Taiwan 921 earthquake. Damage to Wushi bridge appeared in the superstructure, the substructure and the approaches. Typical types of damage are discussed and illustrated in this paper. A review of the bridge design specifications in Taiwan is also presented to give the background on the seismic design of Taiwan highway bridges.
