EXHUMATION OF THE HELLENIC ACCRETIONARY PRISM – EVIDENCE FROM FISSION-TRACK THERMOCHRONOLOGY

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...

Large-scale geomorphology and fission-track thermochronology in topographic and exhumation reconstructions of the Southern Rocky Mountains

Long-term landscape evolution is the integrative sum of constructive rock-uplift processes and destructive erosional processes. For the Southern Rocky Mountains, it has been proposed that Phanerozoic rock uplift and erosion have been influenced by crustal structure that was inherited from the time of assembly of the continent in the Proterozoic. This paper compares large-scale geomorphology and...

Exhuming 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...

Petrogenesis of mantle peridotites from the South of Jazmourian, Makran accretionary prism, Iran

Mantle peridotites exposed in south Jazmourian comprise of lherzolite and porphyroclastic Cpx-bearing harzburgite in the lower part with chromitite lenses in the upper parts. Petrography and microprobe studies shows evidence of melt-peridotite interactions; post melting processes and subsolidus interactions, which has been associated with appearance of two generations of deformed primary pyroxe...
