Aug 01, 1990· The pH of water standing in pools in deposits of kaolin-family clays tends to be low, i.e. pH 4 to 5. Streams draining such clay-containing areas commonly also yield pH values below 7, whereas streams flowing over primary, and clay-parent, silicate rocks typically yield a pH of 7 or higher - hence testing the pH of streams may aid in clay-prospecting in igneous country …

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering …
