Rivers discharge a constant supply of sediment into the world's oceans. This sediment is largely composed of various clay minerals - the products of rock weathering - and organic compounds of plant ...

The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes leading to volcanism and affecting earthquakes. In the lab, scientists ...

A new NASA study suggests that if life ever existed on Mars, the longest-lasting habitats were most likely below the Red Planet’s surface. A new interpretation of years of mineral-mapping data, from ...

Plate tectonics can trigger ice ages through the production of the carbon-trapping mineral smectite, according to a new study. MIT geologists have found that a clay mineral on the seafloor, called ...

This diagram illustrates the distribution of charges on clay particles within a solution and the structure of the surrounding diffuse double layer. The diffuse double layer of clay minerals will form ...

Bentonite is a very old clay that has been used as a remedy for many things. The fine powder forms when volcanic ash ages. It’s named after Fort Benton, WY, which has a lot of it. But it’s found all ...

A new study from two researchers at Binghamton University in New York could shed more light on what happened to water that once existed on Mars’ surface. Geological Sciences and Environmental Studies ...
