Dolores Formation, Uruguay

The Dolores Formation is a geologic formation in Uruguay. The formation is dated to the Late Pleistocene-Early Holocene. Performing optically stimulated luminescence and thermoluminescence methods on sand samples from different locations within the formation produced ages between 32,230 ± 2,640 and 10,570 ± 990 years ago, while a set of calibrated radiocarbon dating based on organic soil, wood, and mammal teeth resulted in ages between 27,436 and 11,857 years ago.^[1]
