  I would hazard a guess the photographer got creative with a UV flashlight given the eerie blue glow on the stone that is not florescent https://www.minershop.com/pages/uvandourhobby https://www.minershop.com/pages/uvandourhobby

  > What is making the rocks luminous, fungus? It is the rocks themselves. Infrared luminescence is the name of the effect. It is a bit like fluorescence except that the emission occurs in the infrared rather than the visible part of the spectrum. https://pubs.usgs.gov/bul/1052c/report.pdf https://pubs.usgs.gov/bul/1052c/report.pdf
