GotAU? 106 Posted February 9, 2020 Share Posted February 9, 2020 (edited) OK here’s my favorite. It is full of terms that you read about in descriptions of mines, mineralogy and geomorphology. Dictionary of Geological Terms: Third Edition (Rocks, Minerals and Gemstones). ISBN 0-385-18101-9 https://www.amazon.com/dp/0385181019/ref=cm_sw_r_cp_api_i_MYfqEb2GVV5AY Post what you like to use as well. Edited February 9, 2020 by GotAU?

Stillweaver hillbelli 325 Posted February 13, 2020 Share Posted February 13, 2020 ge·o·mor·phol·o·gy /ˌjēōˌmôrˈfäləjē/ noun the study of the physical features of the surface of the earth and their relation to its geological structures.

GotAU? 106 Posted February 14, 2020 Author Share Posted February 14, 2020 Understanding geomorphology helps one to know how and where alluvial deposits (placers!) form, what landforms are most likely to indicate certain types of strata, to recognize faults and to merely know and appreciate a simple landscape that much more. I have references to more academic books on it from college, but a simple google search and a basic book on it would be helpful and interesting for those just learning about it.

That is all way above my head. What is "placers"? 1 Quote Link to post Share on other sites

Placer deposits are stream or other gravity deposited minerals. You might be down low in a recent streambed working fine gold for example, and miss older stream channels with richer and more coarse placer deposits higher up on the bank if you don’t know what to look for. I was mapping the geology in a canyon a long time ago in field school, and we found a place with out of place rocks that obviously rolled down from a slide up higher in the canyon. It had quartz and pyrite in some of the rocks and one of the students hiked up the side of the canyon to find where it came out of. Pretty low grade gold ore if anything, but it was pretty. Knowing some basics about rocks and geomorphology helps in the search! Edited February 15, 2020 by GotAU? 1 Quote Link to post Share on other sites
GotAU? 106 Posted February 15, 2020 Author Share Posted February 15, 2020 (edited) Here’s a good free PDF textbook on the fundamentals of geomorphology - Some interesting material, especially the parts about how stream deposits are layered and exposed, how faults expose different layers along hillsides (scarps) and how they fill in, etc. All good stuff for those that want to search: Fundamentals of Geography (free ebook): http://www.ndma.gov.pk/tools/vkc/vkc/Geomorphology/eBooks/1.pdf Edited February 15, 2020 by GotAU? 1 Quote Link to post Share on other sites
Bedrock Bob 4,061 Posted February 15, 2020 Share Posted February 15, 2020 Thanks! That helps a lot. I always wanted to try and find some gold but just didn't know where to start. This makes me want to learn more about it. Maybe someday I will find some too! 1 Quote Link to post Share on other sites

I fell into that! After reading more posts to comments in the forums here, I started to see where you were all over it. I’m obviously a newby here coming from a totally different path, with lots to learn! Edited February 29, 2020 by GotAU? 2 Quote Link to post Share on other sites

I get a kick out of yanking a chain once in a while. No disrespect intended. I have found a little placer gold in the pedimemts as well as some meteorites out on the escarpment. My official job description these days is bottle hugging glass worshiper and midget mind wrestler. So keep on your toes around me. You never know when I am going to start splattering gravy all over the table. I apologize in advance if any gets on your biscuits. 1 Quote Link to post Share on other sites

Thanks for the reply, I didn’t take it personally- it was a “hey, wait a minute, I’ve seen that name before!” moment for me. I’ve only used magnets to look for meteorites in the past, and now gold too as I now have a decent detector for my first time, so really have learned a lot reading here. Thanks!
