Sorry, no etymologies found.
The bauxite is earthy, and usually shows a concretionary or pisolitic structure similar to that observed in residual iron ores (p. 172).
It is thought that the solution and redeposition of the iron by organic acids from plant roots may be at least a contributing cause in the formation of this pisolitic texture.
The most valuable deposits are residual, and some parts have preserved the texture of the original rock, though with great increase in pore space; most of the ore, however, has the typical pisolitic structure.
He saw that the difference between these formations, in their structural aspect, and the hand-specimens in his collection of pisolitic and brecciated minerals was chiefly a matter of size; and that the resemblances in form were very close.
Above this is an ash bed, then a bed of breccia containing fragments of trachyte, then another bed of cinders, which looks like a rough sandstone, but is pisolitic, and contains pebbles of the size of a bean.
The hill crops out through pisolitic limestone, in which marine fossils were observable.
Among other things, barren massive sulphide lenses have been identified at the top of the rhyolitic unit, along with lenses of so-called "pisolitic rhyolite" (likely chert in gel form), typical Selbaie-environment marker horizons.
