terrane
This term is a specialized technical expression used almost exclusively in geology and tectonics. It describes a fragment of crustal material that has been broken off from one tectonic plate and accreted to another, creating a geological "patchwork" where the rock types and history differ sharply from the adjacent landmass.
It is frequently confused with the word "terrain," which refers to the physical topography or the layout of the land. While "terrain" describes the surface appearance (e.g., rugged or flat), "terrane" describes the deep structural and historical composition of the crust.
