- (GEOLOGY) Crude layering of rocks
produced under compression. The layering is approximately parallel to
the bisecting planes of folds, and often results in the rock splitting
because of the parallel orientation of the mineral layers. Mica
and slate are good examples of foliation.
- (TOPOLOGY) A decoration of a manifold
in which the manifold is partitioned into sheets of some lower dimension,
and the sheets are locally parallel. More technically, the foliated
manifold is locally homeomorphic
to a vector space decorated by
co-sets of a subspace.
