Quaternary Glaciations
The Quaternary is synonymous with extensive glaciation of Earth's mid‐ and high latitudes. Although there were local precursors, significant glaciation began in the Oligocene in eastern Antarctica. It was followed by glaciation in mountain areas through the Miocene (in Alaska, Greenland, Icelan...
