- n. One of several imperfectly determined minerals, or mixtures of minerals, all of which are hydrous silicates of alumina, and closely related to or identical with kaolin and kaolinite.
These are intermixed with masses and irregular beds of gray cinders and score, pumice, various kinds of lava, lithomarge, and fuller's earth.
The whole of the hill on which the fort of Gwâlior stands had evidently, at no very distant period, been covered by a mass of basalt, surmounted by a crust of indurated brown and red iron clay, with lithomarge, which often assumes the appearance of common laterite.
The relation between laterite and lithomarge is discussed in p. 353 of the _Manual_, and the occurrence of laterite caps on the highest ground of the country, at two places-near Gwâlior, 'outside of the trap area', is noticed (ibid.p. 356).
