- Abstract
- World Quaternary Deposits, 1996 is a polygon theme representing quaternary deposits worldwide. Attribute information includes the type and age of the deposits.
- Purpose
- For educational, non-commercial purposes. This dataset is appropriate for use in a GIS.
- Supplemental Information
- Quaternary deposits characterize the youngest period (the Quaternary) of the earth's geological history. This period began approximately 1.6 million years ago. The principal features of the period are as follows: 1. A cyclic recurrence of landscape and climatic changes including the recurrence of warm (interglacial) and cold (glacial) periods 2. A cooling climatic trend (recent glacial and interglacial periods were colder than more ancient periods.) 3. A high level of tectonic activity and seismicity (mountains were uplifted several kilometers in some parts of the youngest orogenic zone -- the Alpine zone) 4. The appearance of humans and the settlement of tropical and extratropical areas The earth's landscape was transformed during the Quaternary. Glacial periods were distinguished by specific natural zones. As a result of the degradation of forest zones, hyperzonal structures with prevailing open areas appeared in the temperate and tropical belts. The glacial periods were dry periods, so relief formation and sedimentation were more active during these times. These processes were further encouraged by reductions in the level of the world ocean by 100 meters or more during glacial periods. The last glacial period (known as the Wisconsin or Valdai Ice Age) ended about ten thousand years ago, which is not long ago on the geological time scale. It was replaced by the present interglacial period called the Holocene. As a result of warmer and wetter conditions, forest zones and the contemporary polyzonal structure of the landscape were re-established and the level of the world ocean rose. All these changes facilitated development of denser vegetation cover and a sharp decrease in sedimentation rate. The rate of soil formation increased. Therefore, the lithogenic base of the processes occurring in the components of the present day landscape (soil, vegetation, and animal life) and economy (construction, reservoirs, etc.) is the deposits formed in the last glacial period. These deposits have been exposed and transformed by soil formation in the upper few meters of the earth's surface (shown on the soil maps). Along with these deposits, older Quaternary deposits and, locally, Prequaternary rocks are exposed. However, the basic landscape is formed by complicated Late Quaternary deposits. The complex structure of Quaternary deposits is the result of the wide range of genetic types of deposits formed under different lithoclimatic and geomorphologic conditions.
