Paleo-rock-hosted life on Earth and the search on Mars: a review and strategy for exploration
Here we review published studies on the abundance and diversity of terrestrial rock-hosted
life, the environments it inhabits, the evolution of its metabolisms, and its fossil biomarkers to …

Sulfur and carbon isotopic evidence for metabolic pathway evolution and a four-stepped Earth system progression across the Archean and Paleoproterozoic
The Earth's mantle has provided a ready redox gradient of sulfur compounds (SO 2, H 2 S)
since the stabilization of the crust and formation of the ocean over 4 billion years ago, and …

Anaerobic consortia of fungi and sulfate reducing bacteria in deep granite fractures
The deep biosphere is one of the least understood ecosystems on Earth. Although most
microbiological studies in this system have focused on prokaryotes and neglected …

Questioning the biogenicity of Neoproterozoic superheavy pyrite by SIMS
The Neoproterozoic sulfur isotope (δ34S) record is characterized by anomalously high
δ34Spyrite values. Many δ34Spyrite values are higher than the contemporaneous …

Zircon, titanite, and apatite (U‐Th)/He ages and age‐eU correlations from the Fennoscandian Shield, southern Sweden
Craton cores far from plate boundaries have traditionally been viewed as stable features that
experience minimal vertical motion over 100–1000 Ma time scales. Here we show that the …
