If you like volcanoes, Earth isn’t a bad place to live on. After all, our planet is quite geologically active, and that also translates into a respectable level of volcanism. But when it comes to having a variety of flavors, the Earth can be a bit lacking. A new paper, however, comes to estimate what […]
We mush talk about this.
Quartz is cherished for its properties, but I'm not talking about magic.
New England residents shouldn't panic, though. There won't be a volcanic eruption in their backyard anytime too soon.
There's no need to panic though.
Seismic tremors around Mount St. Helens hint at a new possible eruption in the area. Geological surveys have revealed the interior structure of the volcanic system, and geologists have been able to correlate seismic activity with the activation of the system
Geologists have now found the most compelling evidence of granites on Mars – something which prompts more complex theories about the geology and tectonic activity on the Red Planet. Granites and basalts Granites are igneous rocks, pretty common on the surface of Earth. It is often called a ‘felsic’ (white rock) – because it is […]
New research by The Open University and Lancaster University showed that another type of volcanic eruption in Iceland could cause significant disruption throughout the Old Continent. Published in Geology, the study found magma that is twice as ‘fizzy’ as previously believed, which increases the likelihood of disruptive ash clouds from future eruptions. Magma can […]
Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s tectonic plates. This discovery has very far reaching implications, which can solve some of the long standing geological puzzles, as […]
The general classification splits volcanic eruptions in two: explosive or effusive. An explosive eruption is, well, explosive and violent (think Mount Helens), while an effusive eruption is associated with lava flows (think Hawaii). However, in a new study conducted by New Zealand and UK researchers described another, new type of eruption. Inside volcanoes, magma often […]
The cold, lifeless Vesta asteroid might be a lot more like our planet than astronomers believed – having a very active life in the early stages of the solar system evolution, a study of a Saharan meteorite shows. The planet that wasn’t Vesta might host a magmatic layer under its rocky exterior, allowing minerals to […]
Magma forms much deeper than geologists previously believed, according to a new study conducted by Rice University. Magma and Crust The group led by geologist Rajdeep Dasgupta put very small samples of peridotite under very large pressures, to find out if the rock can liquify, at least in small amounts, as deep as 250 […]
Scientists have for the first time determined the actual permeability of the asthenosphere in Earth’s upper mantle, which is basically responsible for how fast the melt rises towards the surface of the earth, and the results were surprising to say the least. Researchers found that it actually moves 25 times faster than previously assumed, which […]
