Glowing Minerals from a Fossil Deposit

Earlier I posted some pictures of wavellite crystals I found in a Silurian marine fossil deposit. Here they are again, viewed under normal light and under ultraviolet light. They don't just fluoresce, they phosphoresce, meaning that they absorb light and continue to glow after the lamp is turned off. The green circles are the wavellite. The orange matrix is limestone. These were found in Snyder County, Pennsylvania.
