So
where do
plumes come from? Recent work suggests
the outer core.
The
2014–2015 Pāhoa lava flow:
Are more felsic magmas
the result of fractionation or assimilation?
Are granites what's left after more mantle-like
components crystallize and sink or are they formed
by the addition of crustal country rock as the
melt ascends? Recent papers suggest fractionation
may be the dominant process.

Somewhere on the
Pacific Plate . . .
The main Hawaiian
Islands are about 2500 miles southwest of San
Diego. They are the newest additions to the Hawaiian
Ridge, a line of mostly extinct submarine volcanoes
on the northern Pacific Plate. The plate moves
upwards of 3˝ inches per year, on average, to the
northwest. Not concidentally, this movement follows
the trend of the Hawaiian Ridge.
So what are a bunch of
islands doing in the middle of the Pacific Plate?
Ah, funny you should ask ...
