TL;DR: In this article, the authors present an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regards to major glacial landforms and the extent of the respective ice sheets.

TL;DR: The Quaternary is synonymous with extensive glaciation of Earth's mid-and high-latitudes as discussed by the authors, and significant glaciation began in the latest Eocene (ca 35-Ma) in eastern Antarctica, followed by glaciation in mountain areas through the Miocene (in Alaska, Greenland, Iceland and Patagonia), later in the Pliocene (e.g. in the Bolivian Andes and possibly in Tasmania) and in the earliest Pleistocene (i.e.

TL;DR: It has long been known that mountain glaciers and continental ice sheets around the globe reached their respective maximum extent at different times during the last glacial cycle, often well before the global Last Glacial Maximum (LGM; c. 23-19-ka), which is formally defined by peaks in global sea level and marine oxygen isotope records as discussed by the authors.

TL;DR: In this article, the authors present the state of research on Quaternary stratigraphy and geology, with emphasis on glacial deposits, discuss the general scientific ideas and give an overview of the methods of investigation, some of which have rarely been applied elsewhere.
