INERTINITE

Micrinite (Mi)

Occurs in very small rounded grains of high reflectance.
It might originate from liptinites as a coalification product

Macrinite (Ma)

Occurs either as an amorphous matrix or as discrete, structureless bodies of variable shapes. Probably originate from flocculated humic matrix substances

Fusinite (F)

Shows highly reflecting, well preserved cellular structure. originates from ligno-cellulosic cell walls

Semifusinite (Sf)

Shows intermediate reflectance and partially visible cellular structure. Originates from the parenchymatous and xylem tissues of stems, herbaceous plants and leaves, which are composed of cellulose and lignin

Secretinite (Sc)

Composed of commonly round, and equant to elongate bodies without obvious plant structure. Commonlyconsidered to be an oxidation product of resin but it may originate from humic gels

Funginite (Fg)

Consisting of mainly high reflecting single or multi-celled fungal spores, sclerotia, hyphae and mycelia (stromata, mycorrhiza), and other fungal remains

Inertodetrinite (I)

Occurs as discrete small inertinite fragments of varying shape
