Clay mineral crystallinity and crystallite (domain) size data determined by X‐ray diffraction
(XRD) are methods extensively used in the characterization of very low‐grade metamorphic …

Diagenetic clay minerals usually occur as heterogeneous assemblages of submicroscopic
layers consisting of different structure types such as illite, smectite and chlorite, with variable …

Volume 13 of Reviews in Mineralogy presents much of our present-day knowledge of micas.
Since 1984 was too much material available to attempt to cover all of the hydrous …

Instrumental settings for determination of illite/muscovite 'crystallinity'(half‐height width of the

Evidence for the early Postglacial use of upland environments in the Mesolithic in various
parts Britain has been known for a long time. However, until relatively recently such …

High-resolution transmission electron microscopy (HRTEM) measurements of the thickness
of white mica crystallites were made on three pelite samples that represented a prograde …

Stonehenge on Salisbury Plain is one of the most impressive British prehistoric (c. 3000–
