| 説明 | Loess in the Quaternary of Alaska, USA. (photo provided by James Cheshire)"Loess" refers to wind-blown silt deposits. The silt was usually derived from glacial sediments in ancient rivers that drained melting summertime glaciers during the Pleistocene Ice Age. Some loess deposits consist of silt derived from non-glacial sources. Ancient loess deposits that have been lithified into rocks are called "paleoloess" or "loessite".Stratigraphy: Fairbanks Loess, QuaternaryLocality: exposure on the University of Alaska at Fairbanks campus, city of Fairbanks, east-central Alaska, USA |
