Block Motion Changes in Japan Triggered by the 2011 Great Tohoku Earthquake [PDF]

open access: yes, 2017
Plate motions are governed by equilibrium between basal and edge forces. Great earthquakes may induce differential static stress changes across tectonic plates, enabling a new equilibrium state.

Arsenic geochemistry and health

open access: yesEnvironment International, 2005
Arsenic occurs naturally in the earth's crust and is widely distributed in the environment. Natural mineralization and activities of microorganisms enhance arsenic mobilization in the environment but human intervention has exacerbated arsenic contamination. Although arsenic is useful for industrial, agricultural, medicinal and other purposes, it exerts

Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

open access: yesThe Depositional Record, EarlyView.
This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Geochemistry of silicate-rich rocks can curtail spreading of carbon dioxide in subsurface aquifers [PDF]

open access: yesNat. Commun. 5:5743 (2014), 2014
Pools of carbon dioxide are found in natural geological accumulations and in engineered storage in saline aquifers. It has been thought that once this CO2 dissolves in the formation water, making it denser, convection streams will transport it efficiently to depth, but this may not be so.

Organic Geochemistry of a Hydrocarbon-rich Calcarenite from the Chicxulub Scientific Drilling Program [PDF]

open access: yes, 2003
The organic geochemistry of hydrocarbon-rich core material recovered by the CSDP is examined to establish whether hydrocarbons are associated with the migration and emplacement of organic matter by post-impact hydrothermal ...

Radiogenic power and geoneutrino luminosity of the Earth and other terrestrial bodies through time

open access: yes, 2020
We report the Earth's rate of radiogenic heat production and (anti)neutrino luminosity from geologically relevant short-lived radionuclides (SLR) and long-lived radionuclides (LLR) using decay constants from the geological community, updated nuclear ...

Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

open access: yesThe Depositional Record, EarlyView.
Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

New Applications in Gas Geochemistry

open access: yesGeofluids, 2020
Gases present in the Earth crust are important in various branches of human activities. Hydrocarbons are a significant energy resource, helium is applied in many high-tech instruments, and studies of crustal gas dynamics provide insight in the geodynamic

Mercury vapor air–surface exchange measured by collocated micrometeorological and enclosure methods – Part I: Data comparability and method characteristics [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Reliable quantification of air–biosphere exchange flux of elemental mercury vapor (Hg0) is crucial for understanding the global biogeochemical cycle of mercury.
