Dear all,
maybe this request is slightly off-topic.. but perhaps not that much.
During my university years (...a few springs back but you'll be indulgent, I trust), I used to have three petrology atlas books, slim and entirely made of large microphotographs of any rock, sort of A4+ format.
These books came, as said, in a group of 3, each one with a large microphotograph on cover and a broad colored rim. I think the colors of these rims were red for magmatic, blue for metamorphic and green for sedimentary.
Once back from the UK, in the late '90s, I lost them and never found a way to get them back. I'd so much like to buy a copy back but have just no idea about the authors, or the publisher.
Searching for "petrology atlas book" on Google didn't prove helpful; even pictures didn't hold those covers, which I'd recognize spot on if I see them.
Anybody out there with a partiality for petrology and a good lead? Does this description stir any memory?
Many thanks!
