The commonest organic components (macerals) of the Kupferschiefer samples studied are liptinite and unstructured matter, with rare vitrinite and inertinite. Liptinite group consists of liptodetrinite, sporinite, alginite and vitrinite-like bituminite.

Sporinite is thought to be derived from the outer cell wall (exines and perines) of plant spores and pollen (Esau 1965; FreyWyssling and Mühlethaler 1965). The outer wall of spores and pollen contains a highly stable bio-macromolecule which can survive in the process of the coalification over millions of years with full retention of morphology (Brooksa and Shawb 1978).
