Small cabinet (7-10 cm)

Description

White radiating pectolite has formed on a doleritic matrix over very pale green prehnite. Some minor calcite rhombs rest on top of the prehnite. A further white chloritic looking mineral has also formed over the pectolite, but I am not sure what this is.

Old material from this historic and now defunct quarry. There is no damage.
