Native Silver (tarnished yellow) overgrown by Nickeline (pink) and Rammelsbergite (whitish grey rim on Nickeline) and Gersdorffite (light grey, euhedral crystals) and partially replaced by intergrown Acanthite (dull, scratched grey) and Stephanite (slightly lighter, "cleaner" grey)

Locality: Easter-Duffy Deposit, Greater Slave Lake, Northwest Territories, Canada

Plane Polarized Reflected Light, 50X Magnification

Have not had time to take new pictures of my newer rocks, as I have been super busy working on my MSc, so I thought I would upload some reflected light images from my thesis! If it seems like these are something folks want to see, I have loads more where this came from. Plus tumblr has a lack of reflected light microscopy images anyways. Feel free to reach out if you have any questions about this stuff!
