Biolith

As Biolithe (Greek. Bios , life and lithos , rock) are biogenic sediments and sedimentary rocks referred to the most part of the remains of animals, Zoolithe or plants, phytoliths , are made. According to the paleobotanist and petroleum geologist Robert Potonié (1889–1974) , they are divided petrographically into combustible biolites, called caustobiolites , and non-combustible rocks , called acaustobiolites .

The caustobiolites include, for example, coal rock , digested sludge rock such as copper shale and resins . Acaustobiolites include radiolarite (silica schist ) and shell and coral limestone.

Caustobiolites

belongs to the so-called humoliths :

• Peat from raised and flat moors
• Brown coal
• Hard coal

so-called sapropelites are:

• Sapropel
• Gyttja
• Copper slate
• Boghead coal

under Liptolithen one understands:

• Resins
• Amber

Acaustobiolites

Limestone in this sense are:

• Sea chalk
• Reef limestone
• Schill limestone
• Limestone tuff
• Oolites
• Oncolites

Ores:

• White iron ore
• Sea ore
• Minette
• Silicolites (Gurgesteine):
• Kieselguhr
• Radiolarians
• Chert

Biopelite (silt rock):

• Wattenschlick
• Mangrove silt
• Flyschtone
• Wavy lime
