- Clay An argillaceous compound with plastic characteristics when wet.
- However, most of them are argillaceous and have limited porosity and permeability.
- Tyrone, up to a few hundred feet of reddish sandstones occur above a basal conglomerate, and are succeeded by a thin development of argillaceous dolomite, the Upper Permian Magnesian Limestone.
- It was thought to be nothing more than a shattered argillaceous deposit, produced by repeated submarine landslipping and carrying with it exotic blocks ranging in size from small fragments (plate 4.2) up to whole mountains.
- Argillaceous, dark, fine-grained carbonates may also have cryptic fabrics.
- Bockelie (1973), also working with cryptic argillaceous limestones, demonstrated how effectively a simpler technique combining light acid etching with photography using orthochromatic film could enhance fabric contrast and reveal burrow patterns.
- The upper part of this formation tends to be argillaceous, and the thickest clean sandstones are in the lower section.
- Suitable hard argillaceous rocks - mudstones and shales - are found in Wales, Devon, the Lake District and the southern uplands of Scotland, says the report.
- At Kings Weston, Avon, white and blue tesserae were of liassic limestone, yellow were of calcareous sandstone, and greed were of argillaceous limestone.
- It is often useful, however, to be able to visualize the distribution of clays in a sandstone or argillaceous carbonate, since clays are often related to otherwise obscure fabric in these rocks.
