Hi brian.rrr, I too share this interest with you. I look forward to someday being able to identify let's say peridot or malachite in it's raw form. Can you imagine how exhilarating this would be? I am quite interested in checking out some of the websites you mentioned, specially ones including the mineral makeup of certain areas. Thank you for your post and for re-sparking my curiosity regarding this subject:0)
Thanks for the response! Here is a link to a US Geoloical Survey website that can show what minerals they have found in different areas of the US and it looks like they have some global maps as well... good luck! https://mrdata.usgs.gov
