Significance of hornblende in calc-alkaline andesites and basalts
Hornblende occurs in some andesitic and basaltic rocks of calc-alkaline affini1y, where it is commonly associated with olivine. The texture, eruption history, and composition are interpreted to indicate that hornblende commonly forms as a product of reaction between olivine and basaltic and andesitic liquids. The natural hornblendes probably formed within the crust at temperatures between 960o ...
متن کاملThe origin of Mount St. Helens andesites
Smith, D. R. and Leeman, W. P., 1993. The origin of Mount St. Helens andesites. J. Volcanol. Geotherm. Res., 55: 271-303. Mount St. Helens volcano has intermittently produced mainly dacitic products but occasionally erupted a more diverse suite of lavas including basalts and andesites. Petrogenetic relations between these magmas provide insight into the dynamics of the subjacent magma system. M...
متن کاملThe subduction factory: How it operates in the evolving Earth
JULY 2005, GSA TODAY ABSTRACT The subduction factory processes raw materials such as oceanic sediments and oceanic crust and manufactures magmas and continental crust as products. Aqueous fluids, which are extracted from oceanic raw materials via dehydration reactions during subduction, dissolve particular elements and overprint such elements onto the mantle wedge to generate chemically distinc...
متن کاملHistory of thermal and environmental physiology in Japan: the heritage of Yas Kuno
Dr. Yas Kuno was a pioneer in the field of sweat gland physiology. He trained many research scientists who formed the first generation of thermal physiologists. In turn, these investigators recruited qualified investigators, forming the second and third generations of thermal physiologists. At present, the third and fourth generations of investigators are actively engaged in research, expanding...
متن کاملThe origin of the Origin revisited.
Darwin, after his return to England from his fateful voyage on the Beagle, took lodgings on March 7, 1837, near his brother Erasmus’s house on Great Marlborough Street in London.1 He remained there for nearly two years until he was married. In his Autobiography he calls the period from the time of his return to his marriage “the most active ones which I ever spent.‘? During his residence at 36 ...
