Environmental Characteristics of Clays and Clay Mineral ...
Clay minerals have a wide range of particle sizes from 10''s of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides.
Clay Minerals | Cambridge Core
Clay Minerals is an international journal of mineral sciences, published four times a year, including research papers about clays, clay minerals and related materials, natural or synthetic. The journal includes papers on Earth processes, soil science, geology/mineralogy, chemistry/material science, colloid/surface science, applied science and technology and health/ environment topics.
Reactivity of Fe(II) species associated with clay minerals
Mineral-bound Fe(II) species represent important natural reductants of pollutants in the anaerobic subsurface. At clay minerals, three types of Fe(II) species in fundamentally different chemical environments may be present simultaneously, i.e., structural Fe(II), Fe(II) complexed by surface hydroxyl groups, and Fe(II) bound by ion exchange.

· We found that clay minerals can enhance carbonate mineral saturation during O 2 and SO 42– reduction and moderate saturation during Fe 3+ reduction and CH 4 production if the pore-fluid pH and clay mineral pK a values are within ~2 log units of one another. We therefore suggest that clay minerals could significantly modify the environmental ...

Schist: Metamorphic Rock
Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity.
