Smectite and illite/smectite mixed-layer clay minerals in the Ashibetsu coals
International Journal of Coal Geology, 1994Abstract Smectite, K-smectite and illite/smectite (I/S) mixed-layer minerals are found as expandable clay minerals in the Paleogene coal seams of the Ashibetsu coal mine in the Ishikari coal field, Hokkaido, Japan. As K-smectite often exists in tuff, tuffaceous shale and coal near tuff, and only occasionally in shale, the K-smectite is simply thought

In the words of Ross and Hendricks (1945), “Clay minerals . . . are the dominant materials of shales and surficial rocks and so are among the most important structural materials of the earth’s surface.” Clay minerals play a significant role in many aspects of life, ranging from their domination of the properties of the soils and sediments beneath us to

Full Characterization of Smectites
2013Abstract Smectites are the most miscellaneous group of 2:1 clay minerals. Chemical and structural heterogeneity are typical for smectites, and both composition and structure are permanently subject to change in natural systems and technical applications.
