Lava Floods Mars Ancient Plains
2014-03-06 09:30:21

ESA Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found. The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 1000 km to the northwest of...

Iceland's Basalt Pillars Not From Warring Trolls, As Folk Legend Has It
2014-02-04 13:18:11

[ Watch the Video: Trolls Not Responsible For Iceland's Basalt Pillars ] Lee Rannals for redOrbit.com - Your Universe Online Icelandic trolls are not responsible for shaping the basalt pillars found on the island, according to a study recently published in the Journal of Volcanology and Geothermal Research. Folklore says that mysterious basalt pillars found in Iceland were created by a pair of angry trolls who hurled rocks at one another. However, the new study says that these...

Large Magma Chamber Sits Below World’s Most Active Volcano
2014-01-29 13:29:50

[ Watch the Video: What's Bubbling Below The Kilauea Volcano? ] Lee Rannals for redOrbit.com - Your Universe Online University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers have discovered a large magma chamber below the world’s most active volcano. The new discovery is the first geophysical observation that large magma chambers exist in the deeper parts of Kilauea. For the study, the team analyzed the seismic waves that travel through the volcano....

This is the first-time that an artist from New Zealand has dominated Urban airwaves in the United States. Simultaneously,...

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

redOrbit Staff & Wire Reports - Your Universe Online By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated. According to UPI, the researchers recreated the conditions of the Earth approximately 4.5 billion years ago, when much of the world was molten and the crust formed as lava cooled. Their goal was to develop a...

Iceland's Basalt Pillars Formed By Slow Lava And Water
2013-10-09 15:55:39

Brett Smith for redOrbit.com - Your Universe Online Icelandic folk legend has it that the rocky pillars in the country’s Skaelingar Valley were projectiles fired into the ground by armies of warring trolls. However, a new study in Journal of Volcanology and Geothermal Research indicates that these hollow pillars of basalt were formed by a very slow lava flow oozing from Iceland's volcanoes and interacting with water. The researchers’ conclusion is unusual because the mixing of water...

Study Shows Extrusive Volcanism Formed Hawaiian Islands
2013-10-07 09:17:25

University of Hawaii ‑ SOEST A recent study by researchers at the University of Hawaii – Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) and the University of Rhode Island (URI) changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought. Before this work, most scientists...

Supervolcanic Ash Can Transform Into Lava Miles Away From Eruption
2013-08-28 06:33:27

Lawrence LeBlond for redOrbit.com - Your Universe Online New research has taken a closer look at how ash produced from supervolcanoes can turn back into lava once it falls back to Earth. Supervolcanoes, such as the Yellowstone caldera, are capable of producing eruptions thousands of times stronger than normal volcanoes. Such a massive eruption can produce an ash cloud that is so hot it has the ability to re-form into lava once it hits the ground much farther away. This evidence was...

Scientists Uncover Link Between Lavas Erupting On Sea Floor And Deep-carbon Cycle
2013-05-03 08:05:27

Smithsonian Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth. The team's research was published May 2 in Science Express. Elizabeth Cottrell, lead author and research geologist at the Smithsonian's...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....

Eldfell
2014-04-08 12:54:37

Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...

Volcanology
2014-01-12 00:00:00

Volcanology is the study of volcanoes, magma, lava, and related geological, geochemical, and geophysical phenomena. The term volcanology comes from the Latin word Vulcan. Vulcan is the ancient Roman god of fire. A volcanologist is a person who studies the creation of volcanoes, and their current and historic eruptions. Volcanologists frequently visit volcanoes, particularly active ones, to observe volcanic eruptions, collect eruptive products including samples of tephra, lava, and rock....

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,...
