He-Pb ) DOUBLE DATING OF DETRITAL ZIRCONS

Geochronology and thermochronology on detrital material provides unique constraints on sedimentary provenance, depositional ages, and orogenic evolution of source terrains. Typically these ages correspond to crystallization and exhumation or eruption ages, and their combination can be used to more confidently resolve candidate source terrains, establish maximum depositional ages, and constrain the thermal histories of orogenic source regions.

We present examples from Mesozoic aeolian sandstones, both modern and Paleogene fluvial sediments, and active margin turbidite assemblages from the Cascadia and Kamchatka margins. Important results include the fact that detritus from ancient orogens may dominate sediments thousands of kilometers away, crustal melting and exhumation appear to be spatially-temporally decoupled in at least two orogens, and first-cycle volcanic zircons older than depositional age are surprisingly rare in most settings except in the continental interior.

In the case of the Kamchatkan, and possibly Olympic, turbidites, zircon He ages are partially reset. User Name Password Sign In.

Detailed isotopic provenance analyses allow for the reconstruction of sediment sources of the ancient sediment routing systems. Minor sediment contributions from sources located to the S and SE of the basin are seen throughout the section. Please note:

Abstract Synorogenic foreland basin fill of the south central Pyrenees preserves the eroded remnants of the early stages of Pyrenean fold-thrust belt evolution and topographic growth. Detailed isotopic provenance analysis allows for the reconstruction of sediment sources and boundary conditions of sediment routing systems. This study integrates published structural, stratigraphic, and petrologic data, with new geochronometric and thermochronometric data in a four dimensional source-to-sink approach to decipher provenance and thermal evolution during Pyrenean orogenesis.
