Description

Interesting old time classic from the late 1880s: a part of a vug in basaltoid rock is covered by greenish prehnite, which itself is covered by salmon brownish radial crystals of slightly altered pectolite (at least labeled as such, did not analyze - my first visual impression was a needle zeolite like mesolite, etc). Nice old timer from a classic locality.
