Define Stromatolites. Stromatolites synonyms, Stromatolites pronunciation, Stromatolites translation, English dictionary definition of Stromatolites. n. A usually rounded or columnar sedimentary structure consisting of alternating layers of carbonate or
Synonyms Fossilized microbial mats ; Living stromatolites ; Microbialites ; Modern stromatolites Definition Stromatolites are morphologically circumscribed accretionary growth structures with a primary lamination that is, or may be, biogenic. They form centimeter- to decimeter-scale domes, cones, columns, ...
Shark Bay microbialites;Shark Bay thrombolites Definition Stromatolites are microbially mediated sedimentary structures. The best-known examples are thriving in the shallow waters of Hamelin Pool at the southern end of Shark Bay in Western Australia. Among the first modernstromatolitesto be described, ...
19762. This definition maintains traditional terminology, where all microbial structures in Hamelin Pool are referred to as ‘stromatolites’, regardless of degree of lamination3. The first known modern stromatolites with sizes and shapes equivalent to Precambrian forms were discovered in Hamelin Pool,...
Recognition and definition are recurring themes in microbial carbonate research (Semikhatov et al., 1979; Burne and Moore, 1987; Riding, 1999, Riding, 2011; Noffke and Awramik, 2013; Grey and Awramik, 2020; Shapiro and Wilmeth, 2020). Early studies struggled with the question of biogenicity...
A new definition for stromatolites is proposed, namely "Stromatolites are laminated rocks, the origin of which can clearly be related to the activity of microbial communities, which by their morphology, physiology and arrangement in space and time interact with the physical and chemical environment ...
Robert N. Ginsburg (192517), we examine his 1991 seminal paper Controversies about Stromatolites: Vices and Virtues, which summarized current ideas about stromatolites including controversies of definition, whether ancient stromatolites should be interpreted as sedimentary structures, and mechanisms of ...
Despite the commonly-held wisdom perpetuated in most textbooks, stromatolites are not in-and-of-themselves microbial mats. Rather, they are layered sedimentary deposits produced via microbial activity in interaction with the environment (if the biologic definition is employed) and subsequently modified ...
Synonyms Laminated microbialites (see Chapter Microbialites) Definition Stromatolites are lithified laminated organosedimentary deposits produced by the sediment trapping, binding, and/or precipitation activities of microbial communities dominated by photosynthetic bacteria (modified from Awramik, 1992 ). ...
