For more than 150 years, geologic characteristics claimed to be evidence for pre-
Pleistocene glaciations have been debated. Advancements in recent decades, in …

The deep time (pre-Quaternary) glacial record is an important means to understand the
growth, development, and recession of the global cryosphere on very long timescales (106 …

Fjords are glacially carved estuaries that profoundly influence ice-sheet stability by draining
and ablating ice. Although abundant on modern high-latitude continental shelves, fjord …

Whalebacks, roche moutonnées, and S-forms carved on Ediacaran granitoids near Cerro de
las Cuentas, Uruguay, along with overlying diamictites, siltstones, and sandstones …

The response of sediment routing to climatic changes across icehouse-to-greenhouse
turnovers is not well documented in Earth's pre-Cenozoic sedimentary record. Southwest …

Continental glacial deposits are rarely preserved in nature. Recent studies of the LPIA
reveal the presence of periglacial deposits in Northern Chad covering an area of 20,000 km …

Glacial reservoirs have been the focus of numerous studies in various basins around the
world, often with the aim of supporting hydrocarbon exploration and development. These …

The expansion of ice masses across southern Africa during the Late Palaeozoic Ice Age has
been known for 150 years, including the distribution of upland areas in controlling the …

Abstract The Ennedi Plateau in Chad in north-central Africa exposes an outstanding
example of a palaeo-ice stream glacial landsystem of late Palaeozoic age, with an …

Abstract The Gondwana Late Palaeozoic Ice Age is probably best represented by the Dwyka
Group in South Africa. Striated and grooved surfaces or pavements are commonly …
