This rock is predominantly made of the mineral plagioclase feldspar, with minor quartz (pale gray crystals), biotite (dark crystals that flash in the sunlight), and amphibole (dark greenish black crystals). The rising plume of magma that would become the Mount Stuart Batholith punched its ...

Professor: Great, melt or vaporize. This went on for hundreds of millions of years.There was no life here then of course, just fire and molten rock.And no liquid water either, no oceans. And, and when do you think start to change?
The slow crawl of molten rock down barren volcanoes, the diamond-spray of magma as asteroids collided with a liquid slag-heap earth, the distant nuclear reactors in the stars, but nothing that could be called a flame. Fire is the bright twin of terrestrial life. It’s been here as long ...
The day after the conference ended, the first of that magma emerged from the crater of Mount Pinatubo. After a week of intensifying eruptions, on 15 June the volcano exploded cataclysmically, blowing a plume of molten rock, ash and gas as high as 40 kilometres into the atmosphere. Much of...

“Almost half of the planet is molten magma,” said lead study author Tue Giang Nguyen, a doctoral student at York University in Toronto. “The atmosphere created by vaporized rocks spreads around the planet.” Ad Feedback That vaporized silicon dioxide, or quartz, forms clouds and rains or ...
