“…Based on the similarities between the microfossils included in Precambrian stromatolites and cyanobacteria, it has been suggested that oxygenic photosynthesis was carried out by cyanobacteria 3.5 billion years ago [24]. Modern microbialites, including stromatolites, which that are usually called ''microbial mats,'' have been reported in very diverse environments, from freshwater [35] to hypersaline systems [23], and can thrive under a wide range of different temperatures, from polar regions to very hot deserts. While in temperate climates, large living microbial mats and microbialites are mostly restricted to so-called extreme environments where grazing pressure is reduced [27], in brackish and marine tropical environments these microbial structures are probably more widespread.…”

Microbialites are organosedimentary deposits that have built up as a result of the growth and binding of detrital sediment by a benthic microbial community. This study focuses on microbialites built by monospecific populations of cyanobacteria in the south-west lagoon of New Caledonia, where they have been observed down to 20-25 m depth. The aim was to study their photosynthetic and respiratory responses to various light intensities. The Phormidium sp. TK1 microbialite was collected at 19 m depth and the P. crosbyanum (Tilden) microbialite was collected at 0.5 and 13 m depth. Phormidium sp. TK1 showed all the characteristic features of a low-light adapted species. The initial slope of the Photosynthesis versus Irradiance curve for this microbialite was close to the maximum quantum yield indicating an efficient light absorption and utilization at low light. The photosynthesis maximum was located 0.2-0.4 mm below the surface and did not shift with changing light intensity. Respiration rates were low and not enhanced by light; photoinhibition was observed at higher light intensities. In Phormidium crosbyanum (Tilden) microbialites, the photosynthesis maximum shifted downward to lower depths with increasing light, probably as a result of phototactic migration of cyanobacterial filaments, and light-enhanced respiration was observed at light intensities above light saturation. The photosynthetic parameters measured in P. crosbyanum indicate that P. crosbyanum is capable of photo-acclimation at high light intensities. The gross productivity of the different microbialites was comparable to values measured in cyanobacterial stromatolites observed in other shallow environments. However, the microbialites studied here were characterized by a lower respiration / production ratio which indicates a higher growth efficiency.

A Review on Microbialites: a Korean Perspective

Microbialites are defined as rocks formed by microbial organisms. After their first appearance around 3.5 billion years ago, microbialites occur in various depositional environments throughout geological periods. Microbial organisms form microbialites by trapping and binding detrital sediments and/ or precipitating carbonate cements, resulting in formation of various microstructures and mesostructures. Four major types of microbialites are distinguished based on their mesostructures: stromatolite, thrombolite, dendrolite, and leiolite. In the geological records, occurrences of microbialites are influenced by calcium carbonate saturation of seawater and interaction of microbialites with metazoans. Stromatolites mainly flourished during the Precambrian, and diminished as level of atmospheric carbon dioxide declined. On the other hand, thrombolites, mainly formed by calcified microbes, began to flourish from the Neoproterozoic. As metazoans diversified in the Phanerozoic, proportion of the microbialites within sedimentary record declined. Since then, microbialites only occasionally flourished during the Phanerozoic, such as shortly after mass-extinction events. In the Korean Peninsula, microbialites occur in the Neoproterozoic Sangwon System, the Early Paleozoic Joseon Supergroup, and the Cretaceous Gyeongsang Supergroup, which form different shapes according to their age and depositional environments. By performing detailed studies on these Korean microbialites, it is possible to understand how microbes affected geological records and sedimentary environments, as well as their interaction with other organisms.

“…Although occurrences of microbial carbonates of latest Cretaceous and Cenozoic age are increasingly noted, most examples stem from lacustrine settings (Kadolsky & Koch 1988;Rouchy et al 1993;Arp 1995;Camoin et al 1997;Pache et al 2001). In addition to the famous stromatolitic buildups in the hypersaline Hamelin Pool at Shark Bay/Australia (Reid et al 2003), microbial buildups are becoming increasingly known in a variety of modern environments (Feldmann & McKenzie 1998;Laval et al 2000;Arp et al 2003;Gautret et al 2004;Reitner et al 2005). This suggests that reefal microbial carbonates may be more common than usually reported.…”

A Maastrichtian microbial reef and associated limestones in the Roca Formation of Patagonia (Neuquén Province, Argentina)

et al. 2006

We describe a small microbial reef and associated limestones occurring in a Maastrichtian transgressive succession of mixed carbonate-siliciclastic lithologies at Sierra Huantraico near Chos Malal (Neuqué n, Argentina). Strontium isotope data suggest that the reef is of earliest Maastrichtian age. The small reef (0.8 m thick, 2 m wide) is mostly composed of peloidal bindstone, dense stromatolite-cement crusts and thrombolite. Except for some ostracods, no metazoan fossils were found in the reef structure, although the majority of peloids are fecal pellets, probably of larger crustaceans. Small foraminifers with calcite tests and probable green algae have also been noted. Sedimentological data and fossils within and immediately above the reef suggest that the reef was formed in a transgressive systems tract under freshwater to brackish-water conditions. Limestones above the reef are serpulid-bryozoan packstones and intraclast-ooid grainstones. These limestones yield a mixture of typical non-tropical (common serpulids and bryozoans) and typical tropical aspects (common dasycladaceans and ooids). This mosaic is explained by salinity fluctuations, which in our case dominate over temperature in determining the grain associations.Schlü sselwö rter: mikrobielles Riff, Mikrofazies, Maastrichtium, Palä oklima, Patagonien. ZusammenfassungWir beschreiben ein kleines mikrobielles Riff, das in der Sierra Hunatraico (Neuqué n, Argentinien) in einer transgressiven, gemischt siliziklastisch-kalkigen Abfolge gefunden wurde. Nach Strontiumisotopen-Datierung ist das Riff in das unterste Maastrichtium zu stellen. Das kleine Riff (0,8 m Mä chtigkeit, 2 m Breite) besteht ü berwiegend aus peloidalem Bindstone, dichten Stromatolith-Zement-Krusten und Thrombolith. Mit Ausnahme von Ostrakoden konnten keine Metazoen in der Riffstruktur nachgewiesen werden, obwohl die Mehrzahl der Peloide als Kotpillen zu interpretieren sind, die vermutlich auf grö ßere Krebse zurü ckgehen. Kleine Foraminiferen und mö gliche Grü nalgen sind die einzigen zusä tzlich nachweisbaren Eukaryoten. Die Fossilien im Riff und in den ü berlagernden Kalken sprechen fü r ein Riffwachstum unter transgressiven aber hyposalinen Bedingungen. Die Kalke ü ber dem Riff tragen ein gemischtes palä oklimatisches Signal, das sowohl typisch nicht-tropische als auch typisch tropische Komponenten beinhaltet. Dieses Mosaik ist mö glicherweise durch die starken Salinitä tsschwankungen erklä rbar und erfordert ein Ûberdenken der bisherigen Modelle zur klimatischen Steuerung der Karbonatsedimentation.
