A new study has found that a mixing of two different types of magma is the key to the historic eruptions of Mount Hood, Oregon's tallest mountain, and that eruptions often happen in a relatively short time "“ weeks or months "“ after this mixing occurs. This behavior is somewhat different than that of most other Cascade Range volcanoes, researchers said, including Mount Hood's nearby, more explosive neighbor, Mount St. Helens. The research is being reported this week in Nature...

Geologists say an undisturbed chamber of molten rock in Hawaii is offering new insight into the way continental rock is formed. The magma, discovered in 2005 when a geothermal power company drilled a mile and a half deep on one of the islands, is the first contact scientists have had with the molten rock from anywhere other than a volcano, The Washington Post reported Thursday. This is Jurassic Park. This is first contact. Here we see this (continental) stuff being produced in its natural...

Mars is a rocky planet with an ancient volcanic past, but new findings show the planet is more complex and active than previously believed - at least in certain places. Astrobiology Magazine -- Mars is a rocky planet with an ancient volcanic past, but new findings show the planet is more complex and active than previously believed - at least in certain places. Finding those places, however, turns out to be trickier than just looking at landforms like river valleys or lakebeds or searching...

Mars is a rocky planet with an ancient volcanic past, but new findings show the planet is more complex and active than previously believed "“ at least in certain places. Finding those places, however, turns out to be trickier than just looking at landforms like river valleys or lakebeds or searching for specific minerals. "Context is everything," said Philip Christensen, Principal Investigator for the Thermal Emission Spectrometer (TES) on Mars Global Surveyor and for the Thermal...

Rhyolite is an igneous, volcanic (extrusive) rock, of felsic composition, with aphanitic to porphyritic texture. Mineral assembly is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2). Biotite and pyroxene are common accessory minerals. Rhyolite can be considered as the extrusive equivalent to the plutonic granite rock. Due to their high content of silica, rhyolite form highly viscous lavas. They can also occur as breccias or in volcanic necks and dikes. Like obsidian,...
