Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Rock weathering is a key process in global elemental cycling. Life participates in this
process with tangible consequences observed from the mineral interface to the planetary …

Hydrocarbon generation and retention processes occurring within gas shales as a response
to increases in thermal maturation are still poorly constrained. While efforts have been …

Ten borosilicate glass compositions consisting of a ternary sodium borosilicate containing
increasing numbers of some of the key elements (Al, Ca, Zr, Ce) present in nuclear glasses …

Minerals formed by bio-oxidation of ferrous iron (Fe (II)) at neutral pH, their association with
bacterial ultrastructures as well as their impact on the metabolism of iron-oxidizing bacteria …

Chondrites accreted the oldest solid materials in the solar system including dust processed
in the protoplanetary disk and diverse organic compounds. After accretion, asteroidal …

Fossil biominerals and fossils of microorganisms in ancient rocks contain important
biogeochemical signals. Decoding this record may reveal crucial information about the …

Alteration textures in volcanic glass from the seafloor fall into two classes, one suggestive of
abiotic/diffusive hydration and chemical exchange, and another likely to be caused by …

We have performed TEM, Raman microspectroscopy, and NanoSIMS characterization of
borosilicate glass samples altered for nearly 26 years at 90° C in a confined granitic medium …

In phosphate‐rich environments, vivianite (FeII3 (PO4) 2, 8H2O) is an important sink for
dissolved Fe (II) and is considered as a very stable mineral due to its low solubility at neutral …
