Hi, Doug–
Please don't be nervous on my account! You are probably right about an old
slice of Africa being welded onto NA, east of the Appalachians–I don't
know–my knowledge of the various Eastern NA orogenic events is very
cursory…I'm afraid I've become a victim of my own rash generalizations. My
earlier remarks were an attempt to explain in simple terms the general effects
of continental collision and the origin of fold mountains. I just threw in the
the Appalachians as an example, without intending to get into details of timing
of local events or complications of re-rifting. Sorry if I started a ruckus!
