An Ocean's Worth Of Water May Be Sitting In North American Mantle
2014-06-13 10:28:29

Brett Smith for redOrbit.com - Your Universe Online While all of Earth’s oceans may seem like more than enough water for one planet, a new study published in the journal Science has revealed an ocean’s worth of water may be sitting in the mantle, hundreds of miles below North America. According to the study, molecular water is stored away in a mineral called ringwoodite about 400 miles below the Earth’s surface. The study team said this stored water is sitting in a transition...

Study Shows Most Of The Sand In Alberta's Oilsands Came From Eastern North America

University of Calgary University of Calgary-led research is first of its kind, uncovering the origin of oilsands sediment They're called the Alberta oilsands but most of the sand actually came from the Appalachian region on the eastern side of the North American continent, a new University of Calgary-led study shows. The oilsands also include sand from the Canadian Shield in northern and east-central Canada and from the Canadian Rockies in western Canada, the study says. This...

April Flowers for redOrbit.com - Your Universe Online The first terrestrial sample of a water-rich gem that reveals new evidence about the existence of large volumes of water has been discovered by an international team of scientists which was led by University of Alberta's diamond scientist, Graham Pearson. Analysis of the gem, called ringwoodite, reveals that it contains a significant amount of water — 1.5 percent of its own weight. These findings, reported in a recent issue of...

Australian Rock Determined To Be Oldest Material Formed On Earth

[ Watch the Video: The Oldest Rock On Earth ] Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature Geoscience, say a rock in Australia is helping to paint a picture of how our planet became habitable 4.4 billion years ago. The team found data from a tiny fragment of zircon that confirms the Earth’s crust first formed 4.4 billion years ago, which is just 160 million years after the formation of the Solar System. John Valley,...

Diamonds In Earth's Oldest Zircons Are Fragments Of Polishing Compound

University of California - Riverside As is well known, the Earth is about 4.6 billion years old. No rocks exist, however, that are older than about 3.8 billion years. A sedimentary rock section in the Jack Hills of western Australia, more than 3 billion years old, contains within it zircons that were eroded from rocks as old as about 4.3 billion years, making these zircons, called Jack Hills zircons, the oldest recorded geological material on the planet. In 2007 and 2008, two research...

Scientists broke new ground in the study of deep earthquakes, a poorly understood phenomenon that occurs where the oceanic lithosphere, driven by tectonics, plunges under continental plates – examples are off the coasts of the western United States, Russia and Japan. This research is a large step toward replicating the full power of these earthquakes to learn what sets them off and how they unleash their violence. It was made possible only by the construction of a one-of-a-kind X-ray...

Reassessment of the role of water in plate tectonics Water in the Earth's crust and upper mantle may not play such an important role as a lubricant of plate tectonics as previously assumed. This is a result geoscientists present in the current issue of the scientific journal Nature (13/06/2013) after the examination of water in the mineral olivine. Laboratory experiments over the past three decades have suggested the presence of water greatly weakens the mechanical strength of the...

The mineral kyanite is an aluminium silicate of the sillimanite group (along with andalusite and sillimanite), also called alumino-silicate. It has the formula Al2O3·SiO2 (Al2SiO5). Its hardness varies widely depending on its crystallographic direction, from 5 to 7.5, and it has a specific gravity of 3.56-3.67. It is translucent, usually blue, but possibly white, gray, green, or black. It is usually found in long-bladed crystals or columnar to fibrous structures. Kyanite is used in...
