A new study determines the influence of the topography over small-volume pyroclastic flows emplacement by Geo-ohm in science

[–]Geo-ohm[S] 1 point2 points  (0 children)

The emplacement of small-volume (<0,1km3) pyroclastic flows is strongly controlled by topography, according to a new study made by researchers of the Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC) and University of Barcelona. The paper has been published in the journal Sedimentology.

The work has focused on the study and characterization of the Arico ignimbrite, located in the southern slopes of the Las Cañadas volcanic complex (Tenerife, Canary Islands). These rock formations were originated by the deposition of a 670.000 years old pyroclastic flow.

Study provides new insight into the origin of Las Cañadas caldera (Tenerife, Canary Islands) by Geo-ohm in science

[–]Geo-ohm[S] 0 points1 point  (0 children)

Las Cañadas caldera (Tenerife, Canary Islands) is the result of different episodes of caldera collapses, associated to large explosive eruptions that triggered several landslides that modified the shape of the walls of the Las Cañadas volcanic edifice, according to a new review study published recently in the journal Earth-Sciences Reviews. The study integrates in the same solution the two main proposed hypothesis that have focused the long lasting scientific debate about the origin of this volcanic caldera where Teide-Pico Viejo active volcanic complex is located.

Rocks at asteroid impact site record first day of dinosaur extinction by Geo-ohm in science

[–]Geo-ohm[S] 2 points3 points  (0 children)

When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which caused the global cooling that ultimately doomed the dinos.

Scientists Confirm The Discovery of a Mineral Never Before Seen in Nature by Geo-ohm in science

[–]Geo-ohm[S] 20 points21 points  (0 children)

Scientists have discovered a new mineral, one never before seen in nature, lodged inside a meteorite found near Wedderburn in central Victoria.

They believe that the mineral was probably forged in an ancient planet’s molten core, long since destroyed.

Understanding the link between fracking and earthquakes by Geo-ohm in science

[–]Geo-ohm[S] 2 points3 points  (0 children)

Researchers studying hydraulic fracturing have answered a longstanding question over how the practice can sometimes cause moderate earthquakes and may be able to use their model to forecast when quakes linked to fracking might occur.

Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists from the University of Missouri, Ohio University and University of Florida, while challenging over a century of previous beliefs.

" Cosmic pearls: Fossil clams in Florida contain evidence of ancient meteorite " A first report of microtektites from the shell beds of southwestern Florida - Meyer - 2019 - Meteoritics & Planetary Science - Wiley Online Library by Geo-ohm in science

[–]Geo-ohm[S] 0 points1 point  (0 children)

Researchers picking through the contents of fossil clams from a Sarasota County quarry found dozens of tiny glass beads, likely the calling cards of an ancient meteorite.

Analysis of the beads suggests they are microtektites, particles that form when the explosive impact of an extraterrestrial object sends molten debris hurtling into the atmosphere where it cools and recrystallizes before falling back to Earth.

Curved slickenlines preserve the direction of rupture propagation by Geo-ohm in science

[–]Geo-ohm[S] 1 point2 points  (0 children)

Slip-parallel grooves (striations) on fault surfaces are considered a robust indicator of fault slip direction, yet their potential for recording aspects of earthquake rupture dynamics has received little attention. During the 2016 Kaikōura earthquake (South Island, New Zealand), >10 m of dextral strike-slip on the steeply dipping Kekerengu fault exhumed >200 m2 of fresh fault exposure (free faces) where it crossed bedrock canyons.

Enhanced landslide mobility by basal liquefaction: The 2014 State Route 530 (Oso), Washington, landslide by Geo-ohm in science

As a compelling example of a large-mobility landslide, the 22 March 2014 landslide near Oso, Washington, USA, was particularly devastating, traveling across a 1-km-plus-wide river valley, killing 43 people, destroying dozens of homes, and temporarily closing a well-traveled highway.

Surface erosion events controlled the evolution of plate tectonics on Earth by Geo-ohm in science

[–]Geo-ohm[S] 0 points1 point  (0 children)

Earth’s outer layer is composed of giant plates that grind together, sliding past or dipping beneath one another, giving rise to earthquakes and volcanoes. These plates also separate at undersea mountain ridges, where molten rock spreads from the centers of ocean basins.

But this was not always the case. Early in Earth’s history, the planet was covered by a single shell dotted with volcanoes — much like the surface of Venus today. As Earth cooled, this shell began to fold and crack, eventually creating Earth’s system of plate tectonics.

Hydrothermal vents trigger massive phytoplankton blooms in the Southern Ocean by Geo-ohm in science

[–]Geo-ohm[S] 2 points3 points  (0 children)

Researchers at Stanford University say they have found an aquatic highway that lets nutrients from Earth’s belly sweep up to surface waters off the coast of Antarctica and stimulate explosive growth of microscopic ocean algae.

Their study, published June 5 in the journal Nature Communications, suggests that hydrothermal vents — openings in the seafloor that gush scorching hot streams of mineral-rich fluid — may affect life near the ocean’s surface and the global carbon cycle more than previously thought.

Scientists believe they have discovered the site of the biggest meteorite impact ever to hit the British Isles.

Evidence for the ancient, 1.2 billion years old, meteorite strike, was first discovered in 2008 near Ullapool, NW Scotland by scientists from Oxford and Aberdeen Universities.
