Evidence for early Pliocene and late Miocene transgressions in southern Patagonia (Argentina): Sr-87/Sr-86 ages of the pectinid "Chlamys" actinodes (Sowerby)
Numerical ages based on 87Sr/86Sr dating of calcitic shells belonging to the pectinid “Chlamys” actinodes (Sowerby) document the only late Miocene (Tortonian) sea flooding event in the Austral Basin at Cabo Buentiempo (8.95 ± 0.82 Ma, 2 s.e.), and provide evidence of the first documented early Plioc...
