Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown. New research by scientists at the University of Michigan and Peking University in Beijing, China, suggests that the outbursts occur through a process very similar to what happens during explosive volcanic eruptions....

U.S. scientists have used a supercomputer to calculate the iron isotope distribution in Earth's mantle that occurred 4.5 billion years ago. University of California-Davis geochemists said they simulated the conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form, producing the first picture of how different isotopes of iron were initially distributed in the solid Earth. The scientists said their research could result in a wave of investigations...

Billions of years of history have been uncovered with a new technique that is helping scientists paint a picture of how Earth's continents were arranged. Scientists are using the new method to recover rare minerals from rocks and analyze their composition. In addition, researchers claim they can accurately date ancient volcanic rocks for the first time. The early landmasses can be pieced together by aligning rocks that have a similar age and orientation. Scientists say the new approach will...

Carbon dioxide completely "disappears" into the atmosphere at all other volcanoes on Earth Science has unearthed the secret to what might have been alchemy at Oldoinyo Lengai volcano in Tanzania. There, in the ancient East African Rift at a place known to local Maasai people as the Mountain of God, Oldoinyo Lengai spews forth carbon dioxide-laden lavas called carbonatites. The carbonatites line the volcano's flanks like snowballs. Oldoinyo Lengai is the only place on Earth where carbonatites...

New spin on laser-flash analysis Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet. Temperature is an important driver of many geological processes, including the generation of magmas (molten rocks) in the deepest parts of the Earth's crust,...

U.S. geologists say they've determined that as rocks become hotter in the Earth's crust, they become better insulators but poorer conductors. The University of Missouri scientists said their findings from a study of how well rocks conduct heat at different temperatures provide insights into how magmas are formed and will possibly lead to better models of continental collision and the formation of mountain belts. These results shed important light on a geologic question: how large bodies of...

MU researchers found that strain heating can play an important role in crustal melting A University of Missouri study published in Nature this week has found that the Earth's crust melts easier than previously thought. In the study, researchers measured how well rocks conduct heat at different temperatures and found that as rocks get hotter in the Earth's crust, they become better insulators and poorer conductors. This finding provides insight into how magmas are formed and will lead to...

Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. The lava composition indicates that a mantle plume"”an upwelling of intense heat from near the core of the Earth"”may be bubbling to life beneath the soil of the Democratic Republic of the Congo. The findings are presented in the current issue of the journal Chemical Geology."This is the most...

Scoria is a term used by geologists to describe an igneous rock containing many gas bubbles, or vesicules. Scoria forms when magma rich in dissolved gases is vented. As the magma encounters lower pressures, the gasses are able to escape and form bubbles. These bubbles are trapped when the magma cools and solidifies. Volcanic cones of scoria can be left behind after eruptions, usually forming mountains with a crater at the summit. An example is Mount Wellington, Auckland in New Zealand....

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
