    • n laterite A rock of peculiar character, found in India and some parts of southwestern Asia. Its essential features are that it is highly ferruginous and that it forms the superficial covering of the country. In its normal form it is a porous argillaceous rock, largely impregnated with the peroxid of iron, some kinds containing as much as 25 or 30 per cent of metallic iron. Although the laterite is in process of formation at the present time, some of it dates back to the Tertiary, and perhaps as far back as the Eocene. There are two rather distinct forms of this rock. One is extensively developed on the west coast of India, where it forms the surface-rock of the country over wide tracts of the low lands near the sea. This, which is called the low-level laterite, is clearly of detrital origin, and it rests indifferently on various older rocks. The iron it contains appears to be due to the fact that it is formed, in part at least, from the debris of the high-level laterite, and in part to the large quantity of iron ore present in the old volcanic rocks of the region. The origin of the high-level laterite, which is found extensively on the highlands of central and western India, is more difficult to explain. It appears, beyond doubt, to have resulted in considerable part from the decomposition in situ, by atmospheric agencies, of the volcanic rock which it overlies.
