Evidence for an impact-induced biosphere from the δ34S signature of sulphides in the Rochechouart impact structure, France [PDF]
, 2017 The highly eroded 23 km diameter Rochechouart impact structure, France, has extensive evidence for post-impact hydrothermal alteration and sulphide mineralization.

Manganese in the West Atlantic Ocean in context of the first global ocean circulation model of manganese [PDF]
Biogeosciences, 14, 1123-1152, 2017, 2016 Dissolved manganese (Mn) is a biologically essential element, and its oxidised form is involved in the removal of trace elements from ocean waters. Recently, a large number of highly accurate Mn measurements have been obtained in the Atlantic, Indian and Arctic Oceans as part of the GEOTRACES programme.

Methane bursts as a trigger for intermittent lake-forming climates on post-Noachian Mars [PDF]
Nature Geoscience, 10, 737-740 (2017), 2016 Lakes existed on Mars later than 3.6 billion years ago, according to sedimentary evidence for deltaic deposition. The observed fluvio-lacustrine deposits suggest that individual lake-forming climates persisted for at least several thousand years (assuming dilute flow).

Topographic and Faults Control of Hydrothermal Circulation Along Dormant Faults in an Orogen [PDF]
Geochemistry, Geophysics, Geosystems, 2018 AbstractHydrothermal systems involving dormant faults within orogenic belts are rarely targeted for geothermal exploration, partly because of the complexity of the 3‐D topography, the unknown permeability of the fault zones and the basement lithology, and the lack of deep‐level data.

Geochemical and visual indicators of hydrothermal fluid flow through a sediment-hosted volcanic ridge in the Central Bransfield Basin (Antarctica). [PDF]
PLoS ONE, 2013 In the austral summer of 2011 we undertook an investigation of three volcanic highs in the Central Bransfield Basin, Antarctica, in search of hydrothermal activity and associated fauna to assess changes since previous surveys and to evaluate the extent ...

Geological constraints for a conceptual evolutionary model of the slope deformations affecting Mt. Nuovo at Ischia (Italy) [PDF]
, 2015 ischia island was the scenario of several Holocene slope in- stability events occurred at different scales, from shallow mass movements, triggered by meteo-climatic forcing, up to massive rock slope failures such as large debris avalanches these last ...
