Lithology and Stratigraphy of the Quaternary Sediments from the Ameghino Segment of the Atlantic Patagonian Margin

Lithology and Stratigraphy of the Quaternary Sediments from the Ameghino Segment of the Atlantic Patagonian Margin

The paper provides the first lithological and age data from the Ameghino segment of the Atlantic Patagonian Margin. The multiproxy study, which involves lithology, microfossils, magnetic susceptibility, color reflectance, and accelerator mass spectrometry radiocarbon (AMS- 14 C) dating, made it poss...

Zusammenfassung:The paper provides the first lithological and age data from the Ameghino segment of the Atlantic Patagonian Margin. The multiproxy study, which involves lithology, microfossils, magnetic susceptibility, color reflectance, and accelerator mass spectrometry radiocarbon (AMS- 14 C) dating, made it possible to establish the litho- and chronostratigraphic frame of six short (
