Apophyllite and Laumontite

Stylistically, this piece stands out from the others as the crystals are thin and tabular and window clear. The matrix and associated laumontites are a bit friable and unstable, so expect this one to shed in transport. Collected by Buck Keller fall of 1996. Ex George Loud.

Locality: Luck Goose Creek Plant, Loudoun County, Virginia

Composition: potassium-calcium fluoride-silicate
