Numerous two and three phase inclusions in Fluorite.
“Primary and secondary two and three phase inclusions, some with free floating gas bubbles, are common. The primary negative crystals will often display a cubic or tetrahedral form while most secondary “fingerprints” are confined to one or more of the four directions of perfect cleavage possessed by Fluorite.” PhotoAtlas Vol. 1 – Pg. 280“
Primary fluid inclusions normally form as negative crystals or spherical to subspherical voids, or spread as “feathers” parallel to crystal faces, while secondary fluid inclusions form irregular, wavy, undulation planes, or follow the four directions of octahedral cleavage for which fluorite is well known.” – PhotoAtlas Vol. 3 – Pg. 555
