New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

Brett Smith for redOrbit.com - Your Universe Online Sailors aboard the New Zealand Royal Navy vessel HMNZS Canterbury spotted something odd floating in the ocean a few days ago - a bounty of beauty supplies bobbing in the South Pacific. Pumice is typically used in salons to exfoliate dead skin and the lightweight volcanic rock can often be seen floating in the ocean in large groupings. However, it is rarely seen covering a swath of ocean roughly the size of New Hampshire, a sight one...

Pre-eruption Activity In Conduits Affect Volcanic Ejections
2012-07-24 13:53:55

Brett Smith for redOrbit.com - Your Universe Online In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice. These ejections travel extremely fast and can reach internal temperatures between 750 to 1,500 degrees Fahrenheit. The prevailing theory has been that the difference in particle size determined when bubbling magma deep below the volcano converts into a rising stream of gas and...

Australia's Great Barrier Reef Gets A Little Help From Volcanic Eruptions
2012-07-20 06:50:48

redOrbit Staff & Wire Reports - Your Universe Online Have you ever wondered how the Great Barrier Reef came to be? Research conducted by Queensland University of Technology geologist Dr Scott Bryan indicates that volcanic activity in the Southwest Pacific could help to save the Great Barrier Reef, but it could also be what caused it to form in the first place. Dr Bryan and colleagues studied the westward flow or rafting of pumice after volcanic eruptions in Tonga in 2001 and...

Pumice has long been recognized as the original, natural pozzolan–used by the Romans in their impressive 2000+ year-old concrete structures. A landmark study just released by the University of Utah details the performance, longevity and strength advantages of pumice as a concrete-fortifying pozzolan–advantages that are critical for today's high-performance infrastructure and industrial needs. The pumice pozzolan used in the study–HessPozz–was sourced from Hess Pumice...

New Hypothesis: Pumice Proposed As Home To The First Life Forms
2011-10-05 03:48:56

The glassy, porous, and once gas-rich rock called pumice may have given rise to early life forms, according to a provocative new hypothesis on the origin of life published in Astrobiology, a peer-reviewed journal from Mary Ann Liebert, Inc. Martin Brasier, Richard Matthewman, and Sean McMahon, University of Oxford (U.K.), and David Wacey, University of Western Australia (Crawley), contend that pumice has "four remarkable properties" that would enable it to have had "a significant role in...

Volcanic Rafts Played Key Role In Origins Of Life
2011-09-02 12:43:48

  Scientists believe that volcanic rafts could have played a key role in the origins of life on Earth, reports BBC News. Researchers say the rock pumice has the right properties to have prodded the conditions for early life to emerge over 3.5 billion years ago. The "rafts" are found today on shores of islands like the volcanic Greek island of Santorini (Thera). The Oxford University and University of Western Australia scientists said they still need more research to help give...

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....
