Tectonic evolution of the central Annapurna Range, Nepalese HimalayasTectonics - Tập 15 Số 6 - Trang 1264-1291 - 1996
K. V. Hodges, Randall R. Parrish, M. P. Searle
The metamorphic core of the Himalayan orogen, or Greater Himalayan sequence, is a northward tapering prism bound at the bottom by a N dipping family of thrust faults (the Main Central thrust system) and at the top by a N dipping family of normal faults (the South Tibetan detachment system). Research in the central Annapurna Range of Nepal demonstrates a close temporal and spatial associati...... hiện toàn bộ
Kinematics, topography, shortening, and extrusion in the India‐Eurasia collisionTectonics - Tập 11 Số 6 - Trang 1085-1098 - 1992
Xavier Le Pichon, Marc Fournier, Laurent Jolivet
We examine the problem of partitioning between shortening and extrusion in the India‐Asia collision since 45 Ma. We compute the amount of shortening expected from the kinematics of India's motion with respect to Eurasia, using the reconstruction at collision time to put bounds on the possible amounts of surface loss within Greater India and within Eurasia. We then compute the amounts of su...... hiện toàn bộ
Cretaceous tectonic evolution of coastal southern California: Insights from the Catalina SchistTectonics - Tập 14 Số 6 - Trang 1290-1308 - 1995
Marty Grove, Gray E. Bebout
The relatively high‐T, high‐P/T, subduction‐related basement in the Southern California Continental Borderland preserves important information regarding the late Mesozoic tectonic evolution of coastal southern California. Integrated petrologic, geochemical, and geochronological study of the subduction‐related Catalina Schist exposed on Santa Catalina Island documents the formation of lawso...... hiện toàn bộ
Rift asymmetry and continental upliftTectonics - Tập 22 Số 3 - 2003
Carlo Doglioni, Eugenio Carminati, Enrico Bonatti
The topography of ocean ridges and rifts show a distinct asymmetry. The eastern sides of the East Pacific Rise, the Mid‐Atlantic Ridge, and the NW Indian Ridge are, on average, 100–300 m more elevated than the conjugate flank to the west. The asymmetry is maintained when bathymetry is plotted versus the square root of crustal age. A comparable topographic asymmetry occurs in the Red Sea an...... hiện toàn bộ
Crustal structure of the transpressional Variscan orogen of SW Iberia: SW Iberia deep seismic reflection profile (IBERSEIS)Tectonics - Tập 22 Số 6 - 2003
José Fernando Simancas, R. Carbonell, Francisco González Lodeiro, Andrés Pérez Estaún, Christopher Juhlin, P. Ayarza, A. Kashubin, António Azor, D. Martínez Poyatos, Gabriel Ruiz de Almodóvar Sel, Emilio Soler Pascual, R. Sáez, Inmaculada Expósito
IBERSEIS, a 303 km long (20 s) deep seismic reflection profile, was acquired across the Variscan belt in SW Iberian Peninsula. The acquisition parameters were designed to obtain a high‐resolution crustal‐scale image of this orogen. The seismic profile samples three major tectonic terranes: the South Portuguese Zone, the Ossa‐Morena Zone, and the Central Iberian Zone, which were accreted in...... hiện toàn bộ
