What is "alginite"

n. (context petrology English) A component of some types of kerogen, consisting of organic-walled marine microfossils.

Alginite is a component of some types of kerogen alongside amorphous organic matter. Alginite consists of organic-walled marine microfossils, distinct from inorganic (silica)-walled microfossils that comprise diatomaceous earth.

Alginite is a complex soil aggregate of algae based biomass fossil, clay turned volcanic ash and calcium carbonate. This material contains a complete spectrum of minerals, biological, macro- and micro-organisms helping to turn lands fertile again in regions where soil has been severely degraded in the past.

At least two forms of alignite are distinguishable, "alginite A" ( telalginite) and "alginite B" ( lamalginite). The "A" form contains morphologically distinguishable microfossils while the "B" form is more amorphous and film-like.
