    • Foliation The manner in which the young leaves are disposed within the bud. "The . . . foliation must be in relation to the stem."
    • Foliation The process of forming into a leaf or leaves.
    • Foliation (Geol) The property, possessed by some crystalline rocks, of dividing into plates or slabs, which is due to the cleavage structure of one of the constituents, as mica or hornblende. It may sometimes include slaty structure or cleavage, though the latter is usually independent of any mineral constituent, and transverse to the bedding, it having been produced by pressure.

    • n foliation The state of being foliaceous or foliated.
    • n foliation In geology, an arrangement of the constituent minerals of a rock in thinly lamellar or often scale-like forms, the result of which is that the mass splits easily in a certain definite direction. Foliation may be congenital with the formation of the rock itself, or posterior to it: in the latter case the epithet foliated indicates a structure not essentially different from that more generally designated as schistose. The relations of foliation to cleavage are somewhat obscure. The essential difference between them appears to be that cleavage is rarely well developed except in fine-grained, argillaceous rock, which by its effects is usually rendered capable of almost indefinite subdivision in one direction, while foliation separates the rock into bands sometimes quite distinct from each other in mineral character, these bands being also not infrequently more or less irregular in thickness and rather lenticular in form. By some geologists it is thought that in foliation a more advanced stage of metamorphism has been reached than that indicated by cleavage; but it is also highly probable that the original lithological and structural character of the mass had much to do with bringing about the observed differences. See schist and schistose.
    • n foliation In architecture, enrichment with ornamental cusps or groups of cusps, as in the tracery of medieval windows; foils collectively; feathering.
    • n foliation Arrangement by leaves; specifically, a numbering of the leaves of a book instead of the pages.
