Environmental Characteristics of Clays and Clay Mineral ...

The formation of bentonite (beds containing smectite-group clay minerals including montmorillonite) and fuller's earth (a type of clay mineral deposit that has high capacity to absorb water) may occur primarily by diagenesis, although some deposits may also form by hydrothermal processes. Bentonite beds usually form from altered volcanic ash, but other types of rock may also serve as sources ...

Clay - Wikipedia

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...

The only British deposit of potentially workable tungsten ores outside of south-west England occurs within quartz veins associated with the Skiddaw Granite at Mosedale, in the northern Lake District. There have been several short-lived attempts at mining the wolfram and scheelite of this deposit at Carrock Fell Mine, the first in 1854, the most recent ending in 1981; some arsenic was recovered ...

Clay Alteration Associated with Proterozoic Unconformity ...

Clay minerals associated with the unconformity-type uranium deposits of the East Alligator Rivers uranium field have been used to determine the spatial distribution of hydrothermal alteration and the conditions of uranium deposition within the altered basement underlying the Kombolgie unconformity. Alteration develops a similar pattern at regional and smaller scales, with a close relationship ...
