Detection of the deep biosphere in metamorphic rocks from the Chinese continental scientific drilling

期刊: GEOBIOLOGY, ; ()

It is generally accepted that there is a vast, well-populated biosphere in the subsurface, but the depth limit of the terrestrial biosphere has yet to......

Inverse hydrogen isotope fractionation indicates heterotrophic microbial production of long-chain n-alkyl lipids in desolate Antarctic ponds

期刊: GEOBIOLOGY, ; ()

Long-chain (>C-25) n-alkyl lipids have long been considered biomarkers for higher plant leaf waxes and widely applied for paleoclimate and paleoenv......

Constraining oceanic oxygenation during the Shuram excursion in South China using thallium isotopes

期刊: GEOBIOLOGY, 2020; 18 (3)

Ediacaran sediments record an unusual global carbon cycle perturbation that has been linked to widespread oceanic oxygenation, the Shuram negative C i......

Microbial colonization of metal sulfide minerals at a diffuse-flow deep-sea hydrothermal vent at 9 degrees 50 ' N on the East Pacific Rise

期刊: GEOBIOLOGY, 2020; 18 (5)

Metal sulfide minerals, including mercury sulfides (HgS), are widespread in hydrothermal vent systems where sulfur-oxidizing microbes are prevalent. Q......

Biomarker stratigraphy in the Athel Trough of the South Oman Salt Basin at the Ediacaran-Cambrian Boundary

期刊: GEOBIOLOGY, 2020; 18 (6)

The South Oman Salt Basin (SOSB) has been studied extensively for knowledge concerning the habitat of the enigmatic Ediacaran-Cambrian oils that are p......

Formation of large carbonate concretions in black cherts in the Gufeng Formation (Guadalupian) at Enshi, South China

期刊: GEOBIOLOGY, 0; ()

The formation of carbonate concretions is a cementation process which passively infills the pore spaces within sediments. They record the original env......

Paleoenvironmental proxies and what the Xiamaling Formation tells us about the mid-Proterozoic ocean

期刊: GEOBIOLOGY, 2019; 17 (3)

The Mesoproterozoic Era (1,600-1,000 million years ago, Ma) geochemical record is sparse, but, nevertheless, critical in untangling relationships betw......
