2XT-XRPVariscite AlPO4·2H2O
Transparent variscite crystal approximately 2 mm wide. The variscite is in a cavitiy of a leached lazulite crystal. Matrix is quartz sericite with finely dissiminated rutile and pyrite. A 0.25 mm pyrite crystal (cube and pyritohedron habit)is visible in the right foreground.
Specimen collected by Ed and Martha Cunnignham. Photographed using a Canon T3i SLR mounted on a bellows and a 4 x microscope objective. The image is a composite of 31 stacked images taken with 50 micron separation between each stack. Final image processed using Combine ZP.
