Geology news and discussions

Rough diamond hints at vast quantities of water inside Earth

Battle-scarred diamond provides evidence of 'wet zone' 410km below the surface where water is locked up inside minerals

Ian Sample, science correspondent
The Guardian, Wednesday 12 March 2014 18.36 GMT

A small, battered diamond found in the gravel strewn along a shallow riverbed in Brazil has provided evidence of a vast "wet zone" deep inside the Earth that could hold as much water as all the world's oceans put together.

The water is not sloshing around inside the planet, but is held fast within minerals in what is known as the Earth's transition zone, which stretches from 410 to 660km (250-400 miles) beneath the surface.

"It's not a Jules Verne-style ocean you can sail a boat on," said Graham Pearson, a geologist who studied the stone at the University of Alberta. The water-rich zone could transform scientists' understanding of how some of the Earth's geological features arose.

A Future Sea

In the northeast corner of Africa, a largely unnoticed and lurking geological drama is taking place. A great wound in the earth, running roughly along the N-S axis, is slowly opening up, caused by the upward pressure of magma (molten rock) that crumples the sediments and rocks that overlay it. The fault that is widening will ultimately tear asunder the northeast chunk from the rest of the continent, and in time the rupture will open up, permitting the waters coming from the Red Sea in the north to rush in and fill the valley floor, forming a sea. The piece of dismembered African real estate will drift away towards the Indian Ocean, duplicating what happened hundreds of millions years ago when a similar event farther south of the continent resulted in the breakaway island of what is now Madagascar.






The Great Rift Valley, as what the fissure is geologically known, is actually a series of faults that has all sorts of land features that attest to its being geologically active. Valley floors of varying widths are bounded by columns of rock; undulating stretches of lava flows, numerous active and dormant volcanoes, lakes, uplifted sediments.

The geological phenomenon that will result in the formation of this future sea is evidence of a dynamic earth. Our planet’s crust is punctured in many places by magma and broken up by tectonic plates that are pushing past each other, some against each other and others away from each other. Humans are so often reminded every now and then of this by earthquakes and volcanic eruptions that are frequently destructive and deadly.

Pictures of Indonesia’s Sangeang Api volcano which erupted on May 30, 2014.
Fortunately no casualties have been reported, but the ash necessitated
the closure of airports in some parts of Indonesia and in Darwin Australia.

The eruption sent the ash cloud up to 12 miles high.

Eruption and Pyroclastic flow of the Guatemalan Volcano Santiaguito May 2014

Santa Maria (which is known also as Santiaguito) in Guatemala put on quite a show, with impressive explosive eruptions
that produced numerous pyroclastic flows(also known as pyroclastic density currents, or PDCs) during May 2014.
As many of you know, pyroclastic flows are some of the most deadly of the volcanic hazards. However, an intrepid geologist
from the INSIVUMEH (the geological survey of Guatemala which monitors the country’s copious volcanic activity),
got close enough to capture some amazing footage of a pyroclastic flow in action.

Early Earth: A Battered, Hellish World with Water Oases for Life

By Charles Q. Choi, Space.com Contributor
July 30, 2014 01:01pm ET

Asteroids and comets that repeatedly smashed into the early Earth covered the planet's surface with molten rock during its earliest days, but still may have left oases of water that could have supported the evolution of life, scientists say.

The new study reveals that during the planet's infancy, the surface of the Earth was a hellish environment, but perhaps not as hellish as often thought, scientists added.

Geological Features: Earth from above

Mountain structure in central Namibia



Bazman volcano in Iran is featured in this image photographed by an Expedition 38 crew member aboard the ISS on January 5, 2014.



One of the Expedition 38 crew members aboard the ISS recorded this image of the Manicouagan Crater and reservoir located primarily in Manicouagan Regional County Municipality in Quebec, Canada, on January 2, 2014.



The islands, part of the Aleutian Island chain, are actually the upper slopes of volcanoes rising from the sea floor



This sector of the Green River canyon in eastern Utah is known as Bowknot Bend because of the way the river doubles back on itself.

Video shows enormous crack in the ground in northern Mexico

From the article:

Incredible footage has emerged showing a 26ft (8m) deep crack in the in the farmland of northwest Mexico, which stretches for over a kilometre.

The crevice which appeared last week, has disconnected Highway 26 between Hermosillo and the coast, Sky Newsreported.

Drivers, including farm workers, have been forced to navigate around the colossal trench.

Trinity geologists re-write Earth's evolutionary history books

Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought. These life forms were responsible for adding oxygen (O2) to our atmosphere, which laid the foundations for more complex life to evolve and proliferate.

Iceland grows as Bardarbunga volcano continues to spew lava



Quote:
The Bardarbunga volcano's lava field in Iceland is now the size of the island of Manhattan.

Iceland's Bardarbunga volcano is a prolific producer of lava, and thanks to its impressive magmatic output, the island nation is growing.

The activity within the Bardarbunga volcanic system is due to the fact that two massive tectonic plates, the Eurasian Plate and the North American Plate, are drifting apart. As they move away from each other, magma underneath Barbarbunga is rising up to fill the gap and helping to grow the size of the country.

Japan volcano: Mt Ontake rescue teams find 31 bodies

The bodies of 31 hikers have been found near the top of Japan's Mount Ontake a day after a sudden volcanic eruption.

The hikers were not breathing and their hearts had stopped. The search for a total of 45 missing climbers has now been called off for the night.

The volcano, about 200km (125 miles) west of Tokyo, erupted without warning on Saturday, spewing ash and rocks.

About 250 people were trapped on the slopes of the popular beauty spot, but most got down safely.

Court Battle Over Giant Emerald Nears Resolution





An incredible hulk of an emerald weighing 840 pounds was hauled out of a Brazilian mine more than a decade ago and began a global odyssey that ended in Los Angeles Superior Court, where a fight over its ownership is nearing resolution.

On Tuesday, a judge eliminated from consideration gem trader Mark Downie, one of the men claiming ownership of the emerald that has been appraised at $372 million. It is considered one of the largest in the world.

The emerald, that was pulled from a mine in the jungles of Brazil's Bahia state and is known as the Bahia Emerald, is not going to win any beauty contests. According to those who have seen it, it is a hulking brute of a gem, with several thick green rods the size of a man's forearms jutting out of a stone base.

Lawyers said that museums including the Smithsonian and the Getty have expressed interest in obtaining it for their collections. Its value is as an art object, and it can't be broken down to make jewelry, they said.

Icelandic volcano sits on massive magma hot spot

Quote:
Spectacular eruptions at Bárđarbunga volcano in central Iceland have been spewing lava continuously since Aug. 31. Massive amounts of erupting lava are connected to the destruction of supercontinents and dramatic changes in climate and ecosystems.

New research from UC Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth’s surface are essential for generating such large amounts of magma. In fact, the scientists found that the Bárđarbunga volcano lies directly above the hottest portion of the North Atlantic mantle plume.

The study, published online Oct. 5 and appearing in the November issue of Nature Geoscience, comes from Charles Lesher, professor of Earth and Planetary Science at UC Davis and a visiting professor at Aarhus University, and his former PhD student, Eric Brown, now a post-doctoral scholar at Aarhus University.

“From time to time the Earth’s mantle belches out huge quantities of magma on a scale unlike anything witnessed in historic times,” Lesher said. “These events provide unique windows into the internal working of our planet.”

Such fiery events have produced large igneous provinces throughout Earth’s history. They are often attributed to upwelling of hot, deeply sourced mantle material, or “mantle plumes.”
