Dickite (Al2Si2O5(OH)4) is a phyllosilicate clay mineral named after the metallurgical chemist Allan Brugh Dick, who first described it. It is chemically composed of 20.90% aluminium, 21.76% silicon, 1.56% hydrogen and 55.78% oxygen. It has the same composition as kaolinite, nacrite, and halloysite, but with a … See more In 1888, Allan Brugh Dick (1833–1926), a Scottish metallurgical chemist, was on the island of Anglesey to conduct research on kaolin. He performed various experiments describing the clay mineral. It was not until 1931 that Clarence … See more Al2Si2O5(OH)4 is the chemical formula of dickite. The calculated percent abundances are very close when compared to other kaolin minerals. Chemical … See more Dickite takes on the appearance of a white, brown earthy color and is often found embedded in many other minerals such as quartz. See more Dickite was first discovered in Almwch, Island of Anglesey, Wales, UK. Dickite is scattered across Wales forming occurrences in vein assemblages and as a rock-forming mineral.

Differences in chemical composition and crystal structure distinguish the various species.Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists … WebThe Gibbs free energy of formation of the Saint Claire dickite at 25 °C and 1 bar is 12 to 25 kJ/mol less negative than data obtained for kaolinite using the same and different techniques. This trend is unlikely to reverse at higher temperature and/or pressure in the range of kaolin mineral occurrences. Thus, the new data further corroborate ... temporarily exposed replacement
