intercalation

[in‚tər·kə′lā·shən]
(geology)
A layer located between layers of different character.

Intercalation

 

the appearance of new structures and processes in an already formed life system. Examples of intercalation are the articulation of new stages alongside already existing ones in the process of individual development, the formation of secondary venules between the main ones in the wings of insects, and the formation of additional silica in diatomaceous algae.
