Exsolution lamellae require slow cooling and a broad range bulk composition. The exsolution of feldspar for example needs to have abundant Na and K to make lamellae. The compound in the most abundance of the bulk composition will be the main part of the crystal. The smaller proportion will be the lamellae. The unmixing happens due to cation size differential. As the mineral cools it is less willing to have high energy random distribution of the elements. Once a liquid cools to its miscibility gap the mineral creates areas of each compound separately. The lamellae align crystalographically.

What is perthitic texture?
A perthitic texture is an intimate intergrowth of sodic and potassic feldspar resulting from subsolidus exsolution (unmixing of two minerals). Strictly speaking a perthite has blebs or irregular lamellae of sodic feldspar within potassic alkali feldspar, however, the term perthite is often used to describe all types of exsolution in the feldspars. An antiperthite is an intergrowth arising due to exsolution where potassic feldspar is present as blebs or lamellae within a sodic feldspar. The term mesoperthite is used when sodic and potassic feldspars are in broadly equal anbundance. Perthite that can only be observed with the aid of a microscope is known as microperthite. Perthite in which the lamellae are barely visible under a microscope is termed cryptoperthite.

Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
What is The type of lamellae found between osteons?
concentric
What are the central canal and its surrounding lamellae called?
An osteon.
Which is best associated with the plant cell?
Chloroplasts and their lamellae.
What is the area between osteons are filled in with what lamellae?
interstitial
Stacks or grana are connected to each other by?
lamellae
