  • n. The separation of the layers of a laminar composite material as a result of repeated stress, or failure of the adhesive
  • n. The formation of a gastrula by the splitting of the blastoderm

from the GNU version of the Collaborative International Dictionary of English

  • n. Formation and separation of laminæ or layers; one of the methods by which the various blastodermic layers of the ovum are differentiated.

from The Century Dictionary and Cyclopedia

  • n. A splitting apart in layers; a laminar dehiscence: a term specifically applied in embryology to the splitting of a primitively single-layered blastoderm into two layers of cells, thus producing a two-layered germ without invagination, embolism, or proper gastrulation.

Examples

  • It was also shown that what is called delamination -- the rise of the two primary germinal layers by the folding of the surface of the blastoderm (for instance, in the Geryonidae and other medusae) -- was a secondary formation, due to cenogenetic variations from the original invagination of the blastula.

  • [14] In most vertebrated animals this process of gastrulation has been more or less superseded by another, which is called delamination; but it scarcely seems necessary for our present purposes to describe the latter.
