The Great Basin of the western United States has proven important for studies of Proterozoic and Paleozoic geology [2500 to 245 million years ago (Ma)] and has been central to the development of ideas about the mechanics of crustal shortening and extension. An understanding of the deformational history of this region during Mesozoic and Cenozoic time (245 Ma to the present) is required for pali...

A thrust-fold belt consisting of a series thrusts and buckling folds developed in the Mesozoic Cenozoic strata within Kuqa Depression, Tarim Basin. In this study, structural interpretation model Depression is established proto-basin reconstructed on basis outcrop geology along basin margin, seismic, well-log CEMP data. The called ‘delaminate contractional deformation’, which emphasizes decoupli...

Abstract The Ötztal Nappe in the Eastern Alps is a thrust sheet of Variscan metamorphic basement rocks and their Mesozoic sediment cover. It has been argued that main part its southeastern part, Texel Complex, belong to two different Austroalpine nappe systems are separated by major tectonic contact. Different locations have proposed for this boundary. We use microprobe mapping garnet structura...

The Ancient Pacific Margin NATMAP project (Thompson et al., 2000) is a collaboration between the British Columbia Geological Survey Branch, the Geological Survey of Canada and the Yukon Geoscience Office. It aims to advance understanding of the Cordillera-long belt of complexly deformed pericratonic rocks that made up the Pacific margin of North America in Paleozoic to early Mesozoic time (Figu...
