Prehnite ps. Anhydrite with Laumontite (USA classic!)

Item Description

Rich mint-green, translucent, knobby prehnite botryoids are densely intergrown on the sculptural small cabinet pseudomorph. The prehnite has replaced numerous anhydrite crystals on the basalt matrix. Laumontite is RARE from the famous and extinct traprock Prospect Park Quarry and small, contrasting snow-white prisms are nicely scattered on the prehnite. The basal attachment reveals the hollow areas where the anhydrite once was and where the prehnite precipitating fluids flowed. This well-known quarry opened in 1901 and operated into the early 2000s. The quarry pit is being filled in for future housing. Classic prehnite "fingers" with rare laumontite from the locale.
