Abstract Microbiological and geochemical data are presented to characterize the hydrogeochemistry and to investigate extant microbial life in fracture waters 2.4 km below surface, at the Kidd Creek Observatory in Canada. Previous studies identified the world’s oldest groundwaters with mean residence times on the order of millions to billions of years trapped in fractures in Precambrian host rock here. In this study, major ion chemistry, δ18O and δ2H isotopic signatures and dissolved gases in… Expand
In Situ Growth of Halophilic Bacteria in Saline Fracture Fluids from 2.4 km below Surface in the Deep Canadian Shield
This work demonstrates that anaerobic bacteria and known halophilic taxa are present and viable in the fracture waters presently outflowing from existing boreholes, and complements ongoing efforts to describe the microbial diversity in fracture waters at Kidd Creek in order to better understand the processes shaping life in the deep terrestrial subsurface.

A window into the abiotic carbon cycle – Acetate and formate in fracture waters in 2.7 billion year-old host rocks of the Canadian Shield
Abstract The recent expansion of studies at hydrothermal submarine vents from investigation of abiotic methane formation to include abiotic production of organics such acetate and formate, and risingExpand
Spatial and temporal constraints on the composition of microbial communities in subsurface boreholes of the Edgar Experimental Mine
Results indicate microbial community composition in the near-subsurface is highly dynamic at very fine spatial scales within fluid-rock equilibrated boreholes, which additionally supports the role of a relationship for surface geochemical processes infiltrating and influencing subsurface environments.

Tracking the Deep Biosphere through Time
The oceanic and continental lithosphere constitutes Earth’s largest microbial habitat, yet it is scarcely investigated and not well understood. The physical and chemical properties here areExpand
The role of low-temperature 18O exchange in the isotopic evolution of deep subsurface fluids
Abstract Ca-Na-Cl fluids with high concentrations of dissolved reduced gases reside within fractures in crystalline Precambrian rocks around the world, and have been most intensively studied withinExpand
High-resolution, long-term isotopic and isotopologue variation identifies the sources and sinks of methane in a deep subsurface carbon cycle
Abstract This study applies a combined isotope and doubly-substituted isotopologue (‘clumped’) methane approach to samples collected over a 9-year long-term experiment at the Kidd Creek scientificExpand
Novel Microbial Groups Drive Productivity in an Archean Iron Formation
A majority of the microorganisms identified contain genes that would allow them to participate in several element cycles, highlighting that in these deep isolated systems metabolic flexibility may be an important life history trait. Expand
Mineral-hosted biofilm communities in the continental deep subsurface, Deep Mine Microbial Observatory, SD, USA.
It is suggested that host rock mineralogy is an important ecological driver in deep continental biospheres because it can significantly enhance biofilm cell densities and promote selective colonization by taxa putatively capable of extracellular electron transfer. Expand
Possible Tectonic Impact of Biosphere
16 This paper explores the possibility of existence of ultra-deep biosphere (deeper than 17 10 km under the surface) and the biogenic earthquake hypothesis – the idea that sub18 surfaceExpand
A global perspective on microbial diversity in the terrestrial deep subsurface
The diversity of bacterial communities in deep subsurface groundwater is shown to be controlled by aquifer lithology globally, by using 16S rRNA gene datasets collected across five countries on two continents and from fifteen rock types over the past decade. Expand


Sulfur mass-independent fractionation in subsurface fracture waters indicates a long-standing sulfur cycle in Precambrian rocks
It is demonstrated that this sulfate most likely originates from oxidation of sulfide minerals in the Archaean host rocks through the action of dissolved oxidants themselves derived from radiolysis of water, thereby providing a coherent long-term mechanism capable of supplying both an essential electron donor (H2) and a complementary acceptor (sulfate) for the deep biosphere.

Dissolved organic matter compositions in 0.6–3.4 km deep fracture waters, Kaapvaal Craton, South Africa
Abstract The composition of dissolved organic matter (DOM) in extremely deep groundwaters has rarely been investigated. Focusing on deep fracture waters in billion year old rocks in South Africa, weExpand
Bioenergetic Constraints on Microbial Hydrogen Utilization in Precambrian Deep Crustal Fracture Fluids
ABSTRACT Precambrian Shield rocks host the oldest fracture fluids on Earth, with residence times up to a billion years or more. Water–rock reactions in these fracture systems over geological timeExpand
Chemolithotrophy in the continental deep subsurface: Sanford Underground Research Facility (SURF), USA
Evaluating the energetic yield of chemolithotrophic metabolisms and microbial diversity in the Sanford Underground Research Facility (SURF) in the former Homestake Gold Mine, SD, USA suggests a complex spatial mosaic of subsurface primary productivity that is in good agreement with predicted energy yields.
