Pennsylvanian to Cretaceous folds and thrusts in south-central Nevada: evidence from the Timpahute Range by Angela Russo Dr. Wanda J. Taylor, Examination Committee Chair Professor of Geoscience University of Nevada, Las Vegas Understanding Permian and Mesozoic contractional structures from southern California to northern Nevada requires correlation through south-central Nevada. After the Devoni...
The Ordovician radiation of marine life was among the most substantial pulses of diversification in Earth history and coincided in time with a major increase in the global level of orogenic activity. To investigate a possible causal link between these two patterns, the geographic distributions of 6576 individual appearances of Ordovician vician genera around the world were evaluated with respec...
The collision of Baltica and Laurentia during the Caledonian Orogeny happened at c. 400–420 Ma. However, subduction processes also took place before this main collisional phase tectonic history these is still not fully resolved. Seve Nappe Complex in Sweden has recorded earlier phases. Norrbotten (North Swedish Caledonides) comprises four superimposed nappes emplaced by eastward thrusting (from...
Abstract The Finnmark Platform Composite Tectono-Sedimentary Element (CTSE), located in the southern Barents Sea, is a northward-dipping monoclinal structural unit. It covers most of Norwegian Sea where it borders mainland. Except for different age basement, CTSE extends eastwards into Kola Monocline on Russian part Sea. general water depth varies between 200 and 350 m, sea bottom influenced by...
The present paper reviews the geological development of the Faroes part of the NE Atlantic Margin in the Cenozoic Era. The Faroes area is located west of the post-Caledonian rift basin system formed in the Devonian after the collapse of the Caledonian mountains. Tectonic movements and plate reorganizations during several phases have strongly influenced sedimentation and erosion along the Caledo...
The formation of the Tibetan plateau during the India-Asia collision remains an outstanding issue. Proposed models mostly focus on the different styles of Tibetan crustal deformation, yet these do not readily explain the observed variation of deformation and deep structures along the collisional zone. Here we use three-dimensional numerical models to evaluate the effects of crustal rheology on ...
