We have it in claystone porphyry here, in minute round globules, no larger than turnip-seed, dotted thickly over the matrix; or crystallized round the walls of cavities, once filled with air or other elastic fluid; or it may appear in similar cavities as tufts of yellow asbestos, or as red, yellow, or green crystals, or in laminae so arranged as to appear like fossil wood. ❋ Unknown (2004)

This island, from what little I saw of it, appears to be composed of a reddish indurated claystone, very hard, portions of it having evidently been under the action of fire; near the water-side were strong indication of iron, some of the small boulders near the beach had large quantities of iron in their composition. ❋ Unknown (2003)

Many of the hills composed of claystone are neatly devoid of vegetation; their surface being bare and smooth, and of a red or black colour. ❋ Various (N/A)

The walls are hung with hideous shapes and skins of wild beasts; in which ever way I turn, I am attracted by odd shapes, such as the fierce visage of the grizzly bear, the white buffalo and panther; while interspersed among the horns of the cimmaron, elk and bison, are grim idols carved from the red claystone of the desert. ❋ Edwin Eastman (N/A)

In some parts of India, the claystone contains numerous small _nodules_ or lumps of clay iron-stone, which seldom exceed the size of a walnut. ❋ Various (N/A)

And when our decree came to be executed we turned those cities upside down, and we rained down upon them blocks of claystone one after another, marked16 by thy Lord himself. ❋ Unknown (1854)

Here and there are idol figures, of grotesque and monster forms, carved from wood and the red claystone of the desert. ❋ Mayne Reid (1850)

The zoologist carried a meerschaum; the guides smoked out of Indian calumets of the celebrated steatite, or red claystone. ❋ Mayne Reid (1850)

Some of them were sitting around the fire, smoking out of curiously-carved pipes of the red claystone. ❋ Mayne Reid (1850)

We see them light their claystone pipes, and send forth clouds of blue vapour. ❋ Mayne Reid (1850)

The doctor drew out his great meerschaum, Gode filled a red claystone, while Seguin and I lit our husk cigarettes. ❋ Mayne Reid (1850)

The boron and lithium mineralization is contained in a strata-bound formation that is a combination of a claystone unit and a volcanic tuff.

The fossils were discovered by a Chinese geologist in 1978 embedded in bands of blue-gray and red claystone at the base of a hill. ❋ Unknown (2009)

Now that I have worked with the European countries and Japan for the past twenty-five years, learning of their studies of various repository locations, I'm beginning to think that claystone is probably the ideal medium. ❋ Unknown (2009)

In the savana the horse-trail is worn sometimes a foot deep into the ash-gray calcareous claystone, here occasionally seamed with white sti-eaks of earthy lime. ❋ Unknown (1771)
