Fayyum (fossil Deposit)
The Fayum is a region and an important fossil ''Lagerstätte'' in northern Egypt. The region comprises the Faiyum Oasis, Fayum Basin, which is intensively used for agriculture, and adjoining areas; the important areas of discovery are mostly north and west of Lake Moeris, Lake Qarun. The Wadi al Hitan, Wadi al-Hitan, known for its numerous whales, whale fossils and since 2005 World Heritage Site, UNESCO World Natural Heritage Site, forms the south-western end. The deposits of the Fayum belong to various geological formations. They are mainly composed of limestone, siltstone and sandstone. The lower sections consist of marine sediments, while the upper, continental sediments were formed in a coastal landscape. The formation period ranges from the Middle to the Upper Eocene to the Rupelian, Lower Oligocene, which corresponds to an age of around 41 to 28 million years ago. The entire sedimentary complex is overlain by basalt, which dates back to volcanism, volcanic activity around 24 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Qarun Protected Area By Hatem Moushir 2
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...
