Most of the platinum metal extracted around the world comes from the Bushveld Complex located in South Africa, a region believed to have been created out of ancient magma some two billion years ago. However, why that particular area is so rich in platinum and other related metals remained a topic open for debate for ... |

Volcanoes are the result of the tectonic movements of the Earth's crust, when magma from the entrails of the planet goes out as lava. They became present in the legends and mythology of all people living around them, which venerated and feared them at the same time. There are submarine and terrestrial volcanoes,... |

Recently an alternative theory designed to contest the notion that Earth's mantle, the layer between the outer crust and the inner core, might have been solid, suggests that instead it could have consisted of a thick magma 'ocean', slowly flowing beneath the surface.Evidence collected from seismic even... |

Scientists say that it takes less time for a planet to form, than for it to completely cool down and compose a solid crust. The study was based on the small meteorites, which occasionally land on the Earth's surface. Physicists from the Lunar and Planetary Institute in Houston, Texas, UC Davis and NASA, found th... |

The experiment was conceived by the U.S. Department of Energy's Argonne National Laboratory, to determine how oxide glass structures behave under extreme pressures. A diamond cell was uniquely constructed using a microscopic laser, to house pressures up to 32 gigapascals, equivalent to a tenth of the pressure at... |

The world "volcano" comes from the Roman god of fire Vulcan, the equivalent of Hephaistos in the Greek mythology. In the ancient times, people attributed to the volcanoes a supernatural personality, which was worshiped.

Mauna Loa is one of the five volcanoes making up the Hawaii Island, the Earth's largest one, with a volume estimated at about 18,000 cubic miles (75,000 km³).The way the massive volcano is bulging and the swelling could enable the researchers to forecast when the next massive eruption will occur. Better prognose... |

Northwestern US is not given to rest: Mount St. Helens seems to enter the same cycle followed by Kilauea in Hawaii with magma being replaced from an reservoir located under the volcano at the same pace as it goes out as lava at the surface. "While the two volcanoes are different in many respects, St. Helens appears t... |

During the antiquity, people attributed to the volcanoes a supernatural personality, which was worshiped. Now, researchers just focus on achieving the right methods of preventing the volcanic eruptions and decreasing the damages they inflict.Under the terrestrial crust, the rocks are under molten stage, forming the m... |
