Implications of in situ calcification for photosynthesis in a ~3.3 Ga-old microbial biofilm from the Barberton greenstone belt, South Africa
Timing the appearance of photosynthetic microorganisms is crucial to understanding the evolution of life on Earth. The ability of the biosphere to use sunlight as a source of energy (photoautotrophy)… Expand

A Silurian Cold-Seep Ecosystem From the Middle Atlas, Morocco
Abstract Geological and paleobiological attributes described in a carbonate unit from the upper Silurian of the Middle Atlas (Morocco) are interpreted as the result of chemosynthetic processes fueled… Expand

Volcaniclastic habitats for early life on Earth and Mars : A case study from 3.5 Ga-old rocks from the Pilbara, Australia
Within the context of present and future in situ missions to Mars to investigate its habitability and to search for traces of life, we studied the habitability and traces of past life in ∼3.5 Ga-old… Expand

Chemosynthetic microbialites in the Devonian carbonate mounds of Hamar Laghdad (Anti-Atlas, Morocco)
Abstract Veins cutting across the Devonian conical mounds of the Hamar Laghdad Ridge (eastern Anti-Atlas, Morocco) were the carriers of geofluids. Although not completely determined, the composition… Expand

Microbial fabrics from Neogene cold seep carbonates, Northern Apennine, Italy
Abstract A number of hydrocarbon seep-carbonate masses are hosted within Miocene and Pliocene siliciclastic units along the Apennine Range and Sicily, and are mainly composed of micritic and… Expand

Most ancient evidence for life in the Barberton greenstone belt: Microbial mats and biofabrics of the ∼3.47 Ga Middle Marker horizon
Abstract The Middle Marker – horizon H1 of the Hooggenoeg Formation – is the oldest sedimentary horizon in the Barberton greenstone belt and one of the oldest sedimentary horizons on Earth. Herein,… Expand

Differentiating marine vs hydrothermal processes in Devonian carbonatemounds using rare earth elements (Kess Kess mounds, Anti-Atlas, Morocco)
Abstract Petrological and geochemical analyses were carried out on Early Devonian Kess Kess mound limestones of the Seheb el Rhassel Group exposed in the Hamar Laghdad Ridge (Tafilalt Platform,… Expand

Gold accumulation in the Archaean Witwatersrand Basin, South Africa — evidence from concentrically laminated pyrite
Abstract Concentrically laminated pyrite is a relatively common, although volumetrically minor, component of auriferous conglomerates in the Archaean (ca. 3.0–2.7 Ga) Witwatersrand Basin of South… Expand

From black-and-white to colour in the Silurian
Abstract Ironstones and iron-rich limestones regularly occur as components of time-specific intervals of the Palaeozoic as well as in younger times ( Brett et al., 2012--this issue ). Silurian… Expand

Potential fossil endoliths in vesicular pillow basalt, Coral Patch Seamount, eastern North Atlantic Ocean.
The chilled rinds of pillow basalt from the Ampère-Coral Patch Seamounts in the eastern North Atlantic were studied as a potential habitat of microbial life. A variety of putative biogenic… Expand
