Illite and smectite both consist of aluminosilicate layers alternating with interlayers. In illite the charge of non-exchangeable interlayer cations is balanced by a greater net negative charge on the ...
MIT geologists have found that tectonic activity gives rise to smectite, a type of clay that can sequester a surprising amount of organic carbon within its microscopic folds (shown here), over ...
Geologists from MIT have identified smectite, a clay mineral with the unique ability to capture and store carbon for millions of years, potentially cooling Earth's climate. Found within seafloor ...
