Mineral composition and geothermobarometry of Mata basaltic rocks (SouthKerman): An indicator of magma type and tectonic setting
Basaltic volcanic rocks with pillow structures are exposed at the southeasternmost extremity of the Sanandaj-Sirjan zone.They belong to volcanic-sedimentary complexes that formed in a general northwest-southeast to north-south trend. In this research, the mineral chemistry of clinopyroxene and plagioclases are employed to study physicochemical conditions and paleo-tectonic setting during genera...
متن کاملThree-dimensional lithospheric structure below the New Zealand Southern Alps
[1] Uppermost mantle seismic structure below the Southern Alps in South Island, New Zealand, is investigated by teleseismic P wave travel time residual inversion. The three-dimensional tomographic images show a near-vertical, high-velocity (2–4%) structure in the uppermost mantle that directly underlies thickened crust along the NNESSW axis of the Southern Alps. The center of the high-velocity ...
متن کامل36. Late Miocene Paleoenvironments and Tectonic Setting of the Southern
During drilling of Leg 160 in the Eastern Mediterranean (April−May, 1995), Messinian (i.e., uppermost Miocene) facies were identified at a site at the base of the Cyprus slope (Site 968) and at two sites on the Eratosthenes Seamount (Sites 965 and 967). The new results can be compared with the recovery of Messinian evaporites from the Florence Rise west of Cyprus (Deep Sea Drilling Project Site...
متن کاملRapid soil production and weathering in the Southern Alps, New Zealand.
Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack of soil production and weathering rate measurements in Earth's most rapidly uplifting mountains has made it difficult to determine whether weathering rates increase or decline in response to rapid erosion...
متن کاملLichen Dating of Earthquake-generated Regional Rock- Fall Events, Southern Alps, New Zealand
Synchronous regional rockfall events triggered by large earthquakes in the Southern Alps of New Zealand were used to evaluate and improve the lichenometry method for surface-exposure dating. Digital calipers were used to measure the maximum diameter of the largest lichen on many rockfall blocks, using a fixed-area largest-lichen (FALL) sampling strategy. Regional significance of FALL peaks can ...
