Hi, Howard– The mineralogical density difference is indeed a reason I had not mentioned why if either subducts in a collision, it will be seafloor rather than continent. Kamron and I have discussed it before, thus I sort of assumed it, but it is best to spell it out when it has been a while. Temperature dictates that seafloor would "prefer" to subduct rather than crumple, and composition dictates that continents "prefer" the opposite. –Doug
