Flow-banded rhyolite from Vulcano, Italy
Posted by Callan Bentley
I collected only a single rock on my summer travels in France and Italy. (Those of you who know me will realize how extraordinary this low number is!)
It’s a flow-banded rhyolite from Vulcano, in the Aeolian Islands north of Sicily a few weeks ago. It contains porphyritic vesicular basalt xenoliths.
I featured a similar sample on Twitter yesterday on the occasion (supposedly) of “International Rock Day”:
