4He behavior in calcite filling viewed by (U–Th)/He dating, 4He diffusion and crystallographic studies

Fault-filling calcite crystals sampled from the Eocene/Oligocene Gondrecourt graben, Paris Basin, Eastern France, have been studied in order to test the potentiality of calcite (U–Th)/He dating, based on recognized He retention behavior in crystal lattice at surface temperature (Copeland et al., 200...

Description
Summary:Fault-filling calcite crystals sampled from the Eocene/Oligocene Gondrecourt graben, Paris Basin, Eastern France, have been studied in order to test the potentiality of calcite (U–Th)/He dating, based on recognized He retention behavior in crystal lattice at surface temperature (Copeland et al., 2007). The samples have been selected because of their relatively old Eocene to Oligocene precipitation age and cold thermal history (
