Clastic sediment layers, like sandstone (pictured) and shale, form when rock fragments are broken down by weathering – a decomposition process that occurs when rocks come into direct contact ...

When there were extensive regions of the continent above water, the erosion of these areas shed clastic sediments into the continental sea, resulting in large sheets of sandstones and shales. When ...

What we need around this joint is some more geology! Over at Clastic Detritus a graduate students pontificates about all rock and whatnot. His ongoing series Sea-Floor Sunday is one to keep reading.

Clastic sediments from the 1680-1700 Ma and 1650 Ma terranes are compositionally similar to sediments from continental rifts or near-continent back-arc basins. The 1760-1800 Ma terrane appears to ...

A classification of organic particles based upon their degradational state and biological origin is outlined for use in palynological analysis. The classification has been used in various forms since ...

China has discovered large-scale integrated clastic oilfield in deep to ultra-deep layers for the first time in South China Sea, marking a breakthrough in China's offshore oil exploration. An ...

A few years back, when I was doing my master’s in Colorado, we went to a gravel quarry for the clastic sedimentology class I was taking. They were quarrying very recent fluvial sediments laid ...
