Anomalous Mesozoic thermal regime, central Appalachian Piedmont: Evidence from sphene and zircon fission-track dating
A total of 17 sphene and 45 zircon fission track ages (FTA) are reported from the Piedmont Province of Pennsylvania, Delaware, and Maryland, the Reading Prong of New Jersey, and the Newark Basin of Pennsylvania. With the exception of one sphene sample, FTA fall within a relatively restricted age range: sphene 190-217 Ma (average 199 Ma) and zircon 143-218 Ma (average 184 Ma). Near concordance o...
متن کاملFission Fragments Track- Etched Pores in Borate Glass
A study has been made to investigate the detection sensitivity of Borate Glass for the heavily ionizing fission fragment tracks. The latent damage tracks produced by fission fragments in Borate Glass, with and without Aluminium Oxide as an additive, have been studied under a high resolution scanning electron microscope. Tracks have been found and studied only in the Borate Glass samples with no...
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 کاملExhuming the Alps through time: clues from detrital zircon fission-track thermochronology
The European Alps are a mountain belt that is characterized by a series of discrete orogenic events, which have long been recognized. Despite the inherent episodic nature of orogenic evolution, the Alps have been continuously exhumed, mainly by erosion, but also by normal faulting. Since continental collision started in the late Eocene/Early Oligocene evidence for ongoing erosional exhumation h...
متن کاملCooling 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...
