I'm not a geologist, and nor will I ever be a geologist. This is the last ever piece of geology work I will ever have to do.
I have done the work, actually. You can see I found the map and have searched other sources as well, and am only now looking for a little help from people on the internet.
All I was asking was a clarification on the lexicon, as I'm working from an old 1970 map and the newer sources have been updated, but I can't find a complete one (I had found one on BGS, but I would need to pay).
