Dolomite luminescence thermochronometry reconstructs the low-temperature exhumation history of carbonate rocks in the central Apennines, Italy.

ABSTRACT: The lack of available thermochronological methods has so far hampered reconstructions of the cooling and exhumation histories in carbonate rock regions. Here we develop a new trapped charge thermochronometry tool based on the thermoluminescence signal of dolomite. It has a closure temperature range of 45-75 °C and is applicable to carbonate domains with cooling rates of 2-200 °C per million years. This new thermochronometric technique is tested in the central Apennines, where seismogenic, carbonate-hosted normal faulting controls regional neotectonics. Thermoluminescence dating is applied along the northeastern shoulder of the Late Pliocene-Quaternary L'Aquila Intermontane Basin, at the footwall of the extensional Monte Marine Fault. Dolomite samples from the bedrock have a mean thermolumi
