Energy conversion of sunlight by photosynthetic organisms has changed Earth and life on it.
Photosynthesis arose early in Earth's history, and the earliest forms of photosynthetic life …

The ubiquity of Au-bearing arsenian pyrite in hydrothermal ore deposits suggests that the
coupled geochemical behaviour of Au and As in this sulfide occurs under a wide range of …

It is widely assumed that atmospheric oxygen concentrations remained persistently low (less
than 10− 5 times present levels) for about the first 2 billion years of Earth's history. The first …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Recognizing whether a planet can support life is a primary goal of future exoplanet spectral
characterization missions, but past research on habitability assessment has largely ignored …

Construction and assembly of the Geologic Time Scale involves:(a) constructing a relative
(chronostratigraphic) standard scale for key periods in the Earth's rock record;(b) identifying …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

In the low-oxygen Archean world (> 2400 million years ago), seawater sulfate
concentrations were much lower than today, yet open questions frustrate the translation of …

The mineralogy of terrestrial planets evolves as a consequence of a range of physical,
chemical, and biological processes. In pre-stellar molecular clouds, widely dispersed …
