Latest Sedimentology Stories
Geologists at the University of Washington found that a previously unseen landform on Mars could help provide a window into the geological history of the Red Planet.
In a study of the harsh but beautiful White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain dune patterns.
When the water in the Mississippi River rose to 58 feet with a forecast of 60 feet or higher in May 2011, the emergency plan to naturally or intentionally breach the levees, established over 80 years prior, was put in motion.
A stroll on the beach can mean sinking your toes into smooth sand or walking firm-footed on a surface that appears almost solid.
Scientists at TU Delft have successfully matched a layer of sediment from the dunes near Heemskerk to a severe storm flood that occurred in either 1775 or 1776.
Something's up with the weather in Namibia, say geoscientists.
Although the dune ecosystem is unusual, fragile and is protected by the "habitats" directive of the network Natura 2000, its conservation is very vulnerable to the proliferation of car parks, nearby buildings and inadequate boardwalks installed for protection or beach access.
The massive subduction zone earthquake in Japan caused a significant level of soil â€œliquefactionâ€ that has surprised researchers with its widespread severity, a new analysis shows.
HOUSTON, April 11, 2011 /PRNewswire/ -- Texas Rare Earth Resources Corp (OTCQB: TRER) announced today it has begun a stream sediment sampling program at its Round Top Mountain rare earth-beryllium-uranium project in Hudspeth County, Texas which also includes niobium, tantalum and gallium.
A river delta is a landform that is created at the mouth of a river, where the river flows into an ocean, estuary, lake, sea, or reservoir. These deltas are built from the deposition of the sediment that is carried by the river as the flow exit’s the mouth of the river. Over a long period of time, this deposition constructs the distinctive geographic pattern of a river delta. The creation of a delta is made up of three core forms: the bottomset, topset, and foreset/frontset. Bottomset...
In geology, a conglomerate is a rock consisting of other stones that have been cemented together. Conglomerates are sedimentary rocks consisting of subangular clasts and are thus differentiated from breccias, which consist of angular clasts. Both conglomerates and breccias are characterized by clasts larger than sand (>2 mm). There are two varieties of conglomerate, defined by texture: paraconglomerates and orthoconglomerates. Paraconglomerates are one of two varieties of conglomerate...
