Hi Brian,
Interesting, and you are probably dead-right, but I don't think, as a student, I ever really concerned myself with the 'why' because I detested the hours of hand-grinding rock sections with Al powder when I could have been sinking beers or waterskiing!! Especially as the professional slide-maker in the Dept had all this automatic section-making equipment - and here we were 'learning' to make slides the hard way. I think it was my metamorphics lecturer's method of showing us who was in charge .... no wonder I majored in sedimentology and fluvial dynamic systems!!
