Description

A late 1980s specimen from when the Münsterbusch slag dump was landscaped (i collected there as my appartment was some 500 m away at that time, but this is not my find). White hydrozincite with turquoise blueish serpiereite and as the label says smallest white blades of zincaluminite (did not analyze!) on a bit of slag matrix. The  locality is totally reclaimed now, these finds are history.
