discussing some of my own very favorite rocks; meteorites, howlite, etc
Quote:what youre looking at in a meteorite is the adjacent plotzing of taenite and kamacite. One has a Ni ( >30%) and iron of (,50%) and the other has an iron of (>70%) and Ni(,20%). …...really neat looking.
Your ed. in these matters far exceeds mine
Quote:You should polish to 2000 grit and then Al rouge buff.
I don 't even remember the exact sequence but I do remember using at least two grits before the final polish
Quote:(I always send any samples out to get done.
I was far too cheap
Quote:I have no patience in doing thin sections or any kind of polishing any more.
For some reason I too quit that sort of thing, don't know why, when we moved here (Apple Valley, Ca) some 16 years past
Quote:It a skill Ive never acquired and I usually need mineral results reported within 3 or 4 days after discovering them in the field.
I might have been happier with ed. and career in that field than in just the writing end of it
