Volatile-consuming reactions fracture rocks and self-accelerate fluid flow in the lithosphere

Importance Hydration and carbonation are the primary reactions that drive Earth’s volatile cycles. These reactions are characterized by a large increase in solid volume, up to several tens of percent, and can induce fracturing, fluid flow and other reactions. However, no experimental study has succeeded in a net increase in …

A geoscience expert to study why continents split where magma is lacking

D. Sarah Stamps. Credit: Mike Lee The Earth’s surface keeps moving and changing shape, disintegrating and forming new land masses and oceans. In the billions of years of planet Earth’s history, there have been 10 supercontinents, the most famous and recent being Pangea which shattered around 175 million years ago. …

Iisc: the volcanoes of the last mass extinction created the Himalayas | Bangalore News

BENGALURU: Researchers at the Indian Institute of Science (IISc) have built models to determine whether volcanism – a magma eruption on the planet’s surface – that caused the last mass extinction 65 million years ago caused erosion of the Indian continental lithosphere. Following the movement of the Indian Plate, they …

Determining transmissibility of novel variants may help immunization programs and healthcare response – ScienceDaily

As the discovery of the new omicron variant illustrates, new COVID-19 variants will continue to emerge on a regular basis. In an effort to make sense of these new variants, scientists at the Los Alamos National Laboratory have developed methods to quantify how more or less transmissible they are, which …

Arc-bound lava zinc isotopes reveal the recycling of fore-arc serpentinites into the subarc mantle

Credit: Unsplash / CC0 Public domain Serpentinite, formed by low temperature hydrothermal alteration of mantle peridotite, is distributed in the lithospheric mantle at the bottom of the subduction slab (slab-serpentinite) and the corner of the fore-arc mantle above the subduction slab (mantle serpentinite) in the subduction zone. Since they usually …

When two plates slide on top of each other

Through Robert Hazen, Ph.D., George Mason University Tectonic plates are large chunks of the lithosphere – about 50 or 100 kilometers thick, but thousands of kilometers in diameter – and lithospheric plates are displaced when they straddle the asthenosphere, which is mobile and moving. Transformation boundaries are a kind of …

As we fight to recycle lithium-ion batteries, what future for electric vehicles in India?

With countries still chasing Li-Ion batteries, they have been labeled obsolete. They find uses in consumer goods like cell phones, laptops, other electronic devices and even in several industries as a critical input. The best use that makes them the most desirable is their legacy use in electric vehicles or …

A halogen balance of the earth’s bulk silicate indicates a history of early halogen degassing followed by net regassing

Importance Halogens play an essential role in biochemistry and are useful in understanding how planets formed and evolved. As we have found that the traditional way of limiting the halogen balance within the Earth is unreliable, we have developed a method that better utilizes relevant geochemical data and estimated halogen …
