The Volcanic Island Clastic Apron Project (VICAP) entails a case history study of a coupled system, "oceanic island volcaniclastic apron". The source area has a long-term record of chemically distinct rocks/deposits with physically datable mineral phases, so that the submarine and subaerial growth and destruction is reflected in sufficient detail in the volcaniclastic apron. The seamount/island...

The analytical signal method for seismic attenuation (Q) estimation is reviewed and investigated using a 1D surface data model and field VSP data. The error in Q-factor recovery from modelled data using the analytical signal method is better than 7 percent over a range of Q-factors from 25 to 100. The method is applied to the enhanced downgoing P-wave of an offset VSP-survey from Ross Lake, Sas...

Undiscovered, conventional oil and gas resources were assessed in the Senegal Province as part of the U.S. Geological Survey World Petroleum Assessment 2000 (U.S. Geological Survey World Energy Assessment Team, 2000). Although several total petroleum systems may exist in the province, only one composite total petroleum system, the CretaceousTertiary Composite Total Petroleum System, was defined...

The development and structure of Neoproterozoic III volcanosedimentary basins in the northeastern part of the Arabian shield record periods of uplift, erosion, extension, subsidence, compression, and strike-slip faulting that postdated the completion of terrane amalgamation in the northern East African orogen (EAO) and predated the initiation of a passive margin on the northern flank of the Gon...

Cohen, A. S., 1989. Facies relationships and sedimentation in large rift lakes and implications for hydrocarbon exploration: examples from lakes Turkana and Tanganyika. Palaeogeogr., Palaeoclimatol., Palaeoecol., 70: 65-80. Two African lakes, Turkana and Tanganyika, illustrate a spectrum of sediments and facies architectures which can occur in large rift lacustrine basins. They demonstrate cont...

Calcite-mineralized wood occurs in marine sedimentary rocks on Vancouver Island, British Columbia at sites that range age from Early Cretaceous to Paleocene. These fossil woods commonly have excellent anatomical preservation resulted a permineralization process where calcite infiltrated buried under relatively gentle geochemical conditions. Wood specimens typically occur calcareous concretions ...

Thermophysical properties of rock and soil are important parameters that affect the efficiency shallow geothermal energy utilization. This paper analyzes thermophysical (specific heat capacity thermal conductivity) their influencing factors based on 6467 sample data in 24 provincial capitals, China. The statistical distributions analyzed histogram plots. Linear regression analysis is conducted ...

The Carboniferous Karashayi Formation in Tahe Oilfield is one of the most promising formations field clastic rocks Oilfield, which rich hydrocarbon resources, but stratigraphic framework unclear, restricts exploration formation. features and seismic section analysis area combined with oil gas distribution are used to analyze reservoir control factors Formation. results show that lower part sedi...

We refined the age of carbonate and clastic volcanomictic rocks Toupugol'egart Formation (D1–2tg) Voikar Belt Polar Urals, which formed at final stage Ural Island arc development. The analysis stratigraphic distribution fossils was based on a revision previously published data new collections authors (algae, tabulatomorphic corals). range extended up to Karpinsky-Langur regional stages Emsian E...
