Summary[edit]
DescriptionBrown Bluff-2016-Tabarin Peninsula–Volcanic tephra.jpg |
English: Block of tephra, at Brown Bluff, Tabarin Peninsula, Antarctic Peninsula. To give an idea of scale, the height at the center of the object is at least 6 ft (1.8 m). Per Skilling, I. P. (1994). Evolution of an englacial volcano: Brown Bluff, Antarctica. (not publicly available on line, and I was only able to read the first two pages), it appears to be "alkali basaltic" in composition (at least the Brown Bluff tephra in general appears to be), I think this is referring to the darker solid chunks contained in the lighter matrix material. |
