Geochemical cycling of arsenic in magmatic systems across supercontinent cycles [PDF]

Scientific Reports
Arsenic (As) cycling in magmatic systems is influenced by tectonic and magmatic processes, yet its long-term behavior is not well understood. This study uses global whole-rock geochemical data of igneous rocks to examine As concentration variations over ...

Reconstructing Earth’s atmospheric oxygenation history using machine learning

Nature Communications, 2022
Earth’s oxygenation history can be reconstructed using machine learning and mafic igneous geochemical data. Agreement with independent proxy predictions for surface conditions implies that interior processes are critical in atmospheric oxygenation.

Battery Earth: using the subsurface at Boulby underground laboratory to investigate energy storage technologies

Frontiers in Physics, 2023
Renewable energy provides a low-carbon alternative to power generation in the UK. However, the resultant supply varies on daily, weekly and seasonal cycles, such that for green energies to be fully exploited new grid-scale energy storage systems must be ...

Health Benefits of Geologic Materials and Geologic Processes [PDF]

International Journal of Environmental Research and Public Health, 2006
The reemerging field of Medical Geology is concerned with the impacts of geologic materials and geologic processes on animal and human health. Most medical geology research has been focused on health problems caused by excess or deficiency of trace elements, exposure to ambient dust, and on other geologically related health problems or health problems ...
