Fold mountains
Hi, Jon–
I would be a bit stirred up if Mauna Loa 'spit' rocks forcefully or a lot
stirred up if it brought up continental rock. I have heard mention of
volcanoes bringing up presumed mantle rock fragments, but do not recall what
type of volcano that was. I have a fuzzy notion it was some sort other than
the really fast, forceful eruption that I gather produces kimberlite with
diamonds, but was it ordinarily-explosive eruptions (whatever I mean by that)
or peaceful ones like Mauna Loa favors?
