It was recently recommended on an FB page that I read some field guides on rock and mineral ID. This was in response to some specific observations I made with material I had collected and with reference specimens I had bought. The suggester offered no further advice or any response to my observations which he didn’t read through. At least five people gave him a thumbs up. That’s extremely discouraging when all I was trying to do was help.
Well, I have a few books. Quite a lot, actually. But you have to go beyond books to learn more. You can’t teach a geology course without lab work or field trips. Books are fine but rocks and minerals and prospecting are also hands on.
To make specific, this poster stated that, among other things, that some sedimentary rocks do not fizz under acid. But he didn’t tell me which ones. Nothing of his personal experience with this, just an admonition to read some books. None of the books I have read list the sedimentary rocks that do not respond. I was trying to learn, not sure what he was trying to do. I was sharing my experiences and observations, he was sharing nothing but negativity.
This is a look at part of my reference collection of over two hundred rock types and various minerals. They are mostly hand or teaching specimen size. All labeled in detail. At any time I can pull something out to test or experiment it using my hardness picks, my acid, my metal detectors, my UV lamps, my black and white streak plates, my super magnet, my microscope, or my geiger counters. No, I don’t have something for specific gravity. I’m working on that. If I can’t identify something complex, which is too often the case, I send it on for lab results. I’m not a know-it-all, I am trying to be a know-it-all.
As a footnote, I’ve quit that group. This is the second major rock related group I have quit in the last year. If you think I can help you, give me an e-mail. I may not have the right answer but I will try to help. Without insulting you.
