English

Subject field(s)
  • Paleontology
  • Petrography
CONT

Columnar stromatolites were abundant and widespread in the Proterozoic but are exceedingly rare in modern seas. ...the subtidal columnar stromatolites have a significant component of algal eukaryotes dominated by motile diatoms with mucilaginous tubes.

CONT

The Hoyt formation is extremely fossiliferous with columnar, domal and planar stromatolites and trilobites.

OBS

Stromatolites (from Greek stroma, mattress, bed, stratum, and lithos, rock) are defined as "attached, lithified sedimentary growth structures, accretionary away from a point or limited surface of initiation." A variety of stromatolite morphologies exist including conical, stratiform, branching, domal, and columnar types.

OBS

columnar stromatolite: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Paléontologie
  • Pétrographie
CONT

[...] l'action des vagues et des courants ainsi que l'accumulation de sédiments détruit localement le tapis, limitant la croissance algaire à des zones légèrement surélevées, à l'abri relatif des apports sédimentaires. Au fil du temps, le relief tend à s’exagérer, et a former une ride ou une colonne stromatolithique.

OBS

Un stromatolithe ou stromatolite (du grec strôma, tapis, et lithos, pierre) est une roche calcaire et/ou une structure marine biogénique et organique laminée double-couche (On parle aussi parfois de «thrombolite»).
