mesosome

[mes´o-sōm]

an invagination of the bacterial cell membrane. Various mesosomes are associated with DNA replication, cell secretion, and electron transport.

The proportion of mesosome and leucosome in metatexites is highly variable; the amount of leucosome sometimes prevails over the amount of mesosome.

Metatexites underwent only a partial segregation of quartz- and plagioclase-rich melt, and the characteristic banding of these rocks originated with distinctly separated bands of newly formed leucosome and restitic mesosome. The complete separation of newly formed granitic melt occurs in diatexites only.

Metatexites are characterized by a prominent interlayering of mesosome with leucosome.
