Looking for life in the deep Earth

Nearly a mile underground in the Northeast part of England, there are crystals and life, so that’s where I went.

Steel beams support the mine walls along a salt road 1.1 km below the surface of the Earth.
Boulby Mine viewed from the road.
Halite crystal found near the Dark Matter Lab, field of view is approximately 3 inches.
Back lighting the polyhalite shows off the strong banding.

Other minerals that were found in the Boulby Mine. Top Row (left to right) trambathite (black) in sylvite (red) and halite (grey) rock, mirabilite grown from evaporated brine fluids, and volkovskite blades. Bottom Row (left to right) boracite with higardite, a neat halite stalactite, and anhydrite pseudomorphs after gypsum.

Keeping science accessible. Researching how minerals can be used to solve problems like climate change, pollution, and disease. @ NHMLA, USC, NASA-JPL
