I would love to find some Nephrite when I am out too. I have some that I found when a friend brought us to his claim years ago. I have that in my rock tumbling video " Nephrite Jade, Petrified Wood, Lysite Agate, and other tumbled rocks" . I have also found a small piece of Forest Green Nephrite in my yard that is in the "A sample of rocks we find in our yard in Wyoming... " video, along with piece that I cut withe Nephrite embedded in the rock.
Red rocks appear to be jasper or agate-chalcedony form of fine crystalline quartz. This is the same mineral(s) that replaced the organic matter in the petrified wood you collected in the same area. Probably Triassic/Jurassic in age. I’m not sure as I’ve not studied the geology in that area, I’m just speculating. First time viewer, I’ll be looking forward to more. I’m thinking that some of the darker rocks are flint with opalized surfaces. I recommend acquiring a mineralogy field handbook at your local book store or from Amazon; preferably one with color pictures and geographical and formation environments analysis. This will help you at lease have a better chance of trying to determine the types of rocks and how they were formed that you collect. Thank you!
