Bioerosion by microorganisms is termed microbioerosion. In aquatic systems, microbioerosion affects various substrates, most commonly relatively soluble ones such as sulfates, phosphates, and carbonates. However, the record ...

Reconciling interpretations of geochemical, sedimentologic, and stratigraphic observations is a common challenge with many datasets, especially those from paleolake systems. The Triassic Cerro de las Cabras and Cerro Puntudo ...

The Ullum-Zonda tectonic depression located in the central Andes Precordillera records several lacustrine episodes from frequent natural damming of the San Juan River during the late Quaternary. We analyzed stratigraphic, ...

The timing, structure, and landscape change during the Patagonian Ice Sheet deglaciation remains unresolved. In this article, we provide a geomorphic, stratigraphic, and geochronological deglacial record of Río Cisnes ...

The climatic changes that occurred during the late Pleistocene-early Holocene in Patagonia generated a glacial retreat, which brought along with it the formation of proglacial lakes (in contact with ice) and periglacial ...

During the last deglaciation, the Bolivian Altiplano (15–23°S, 66–70°W) was occupied by paleolake Tauca covering, at least, ?51,000 km2 at its maximum highstand between 16.5 and 15 ka. Twenty-five hundred years later, after ...
