Hello Rock People! This is Dave the Geology Dude! There is more to this video than just a spinning fossil or rock. There are detailed notes in the video description area. If you want more, longer length rock identification videos are on the GeologyDude homepage. Check them out, or leave a comment here!
The differences are subtle, but Phyllite is one of the more difficult to identify. You were close with choosing Slate-but unfortunately not correct this time. Slate is barely reflective like a blackboard, while phyllite has more of a reflective surface sheen than slate (w/o being too sparkly)…. Often, seeing a variety of the same rock type helps to learn exactly what key features are important. I plan to progressively add more rocks here-to allow this channel to become a better reference resource. Thanks for your comment! I’m doing my best to help folks to learn identification!
