WebApr 10, 2024 · In this study, we integrate the results of structural analysis with new apatite fission track and (U Th)/He thermochronological data to constrain the cooling, exhumation, and uplift history of the Panxi tectonic belt. Thermochronological data reveal that widespread and rapid cooling was initiated during the late Eocene–Oligocene (36–26 Ma ... WebFission track analysis is most used for quantifying tectonic thrusting and normal faulting, surface erosion and basin evolution. The sampling strategies and analytical approaches are an important aspect of answering specific geological questions. We provide examples of such strategies including elevation profiles, multi-method dating, and ...
