Latest Sedimentology Stories
The presence of massive dunes, some over a mile wide and hundreds of yards high, on Saturn’s moon Titan has long puzzled scientists, but the authors of a new study appearing in the current edition of the journal Nature believe they have solved the mystery.
The simple topography of dryland channels presents an interesting paradox according to scientists from UCSB’s Earth Research Institute.
Research by Indiana University geologists suggests that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater river deltas.

Transparency Market Research added a new report "Global Coal Market: Size, Share, Trends, Analysis and Forecasts 2012 - 2018" to its report store.
While flood-control measures have kept the Mississippi River from disrupting commerce and transportation along the waterways of southern Louisiana, they have also reduced the amount of wetland-preserving sediment flowing into the river’s delta.
Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles.
University of Calgary-led research is first of its kind, uncovering the origin of oilsands sediment
For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream.
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...
