Characteristics of 14 Å Clay Minerals in the B Horizons of Podzolized Soils of Alberta
TL;DR: In this paper, the authors investigated the presence of 14 A d spacings in the B horizons of podzolized soils in Alberta and found that the minerals appear to be concentrated in the 2.0-0.2 micron clay fraction, the fraction being comprised primarily of material amorphous to X-ray.

Petrology of the Desmoinesian Excello Black Shale of the Midcontinent Region of the United States
TL;DR: The Excello Shale as mentioned in this paper is one of the best exposed and most laterally continuous of the Pennsylvanian cyclothemic black shales in the mid-continent region of the United States.

A study of a long-spacing mica-like mineral
TL;DR: In this paper, the Fourier transform method was used to analyze the diffraction effects of interstratified clays in terms of a single complex stacking model, and it was shown that the interstation is produced by a three component stacking of 18% single mica layers (A), 10% double mica layer (/~t/~) and 72% allevardite-like layers (,A) in which the A and /~ layers are never together.

Clay mineral assemblages of the Townsend Tuff Bed (Lower Old Red Sandstone), South Wales and the Welsh Borders
TL;DR: The Townsend Tuff Bed as discussed by the authors has widely varying clay mineralogies, which may be divided into five major assemblages showing a general increase in diagenetic grade (from smectite/illite/kaolinite to chlorite and/orillite) to the W. fold.
