Cooling history and exhumation of the nepheline syenites, NW Iran: constraints from apatite fission track
Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...
متن کاملPlio-Quaternary exhumation history of the central Nepalese Himalaya: 1. Apatite and zircon fission track and apatite [U-Th]/He analyses
[1] New apatite and zircon fission track and (U-Th)/He analyses serve to document the bedrock cooling history of the central Nepalese Himalaya near the Annapurna Range. We have obtained 82 apatite fission track (AFT), 7 zircon fission track (ZFT), and 7 apatite (U-Th)/He (AHe) ages from samples collected along the Marsyandi drainage, including eight vertical relief profiles from ridges on eithe...
متن کاملTh~nnal history of Australian passive Inargin cover sequences accreted to Timor during Late Neogene arc-continent collision, Indonesia
Paleotemperature indicators and apatite fission track analysis of Australian continental margin cover sequeRces accreted to the active Banda arc-continent collision indicate little to no heating during rapid late Neogene uplift and exhumation. Thermal maturation patterns of vitrinite reflectance, conodont alteration and' illite crystallinity show that peak paleotemperatures (PPT) increase with ...
متن کاملMesozoic thermal history of the Prebetic continental margin (southern Spain): Constraints from apatite fission-track analysis
Apatite fission-track analysis was applied to Triassic and Cretaceous sediments from the South-Iberian Continental Margin to unravel its thermal history. Apatite fission-track age populations from Triassic samples indicate partial annealing and point to a maximum temperature of around 100–110 °C during their post-depositional evolution. In certain apatites from Cretaceous samples, two different...
متن کاملUplift and thermal history of the Teton Range (northwestern Wyoming) defined by apatite fission-track dating
In order to determine the pattern and timing of exhumation and uplift in the Teton Range, fission-track analysis of apatites has been applied to three sections encompassing ~ 2 km of vertical relief along the Teton escarpment. The resulting data provide new insights on the doming of the Precambrian-Cambrian unconformity and on the Teton exhumation/uplift history prior to the Miocene initiation ...
