Lengenbach Quarry

Mindat lists 185 mineral species from the site, including 51 for which it is the type locality.

I will say, the majority of these species are not going to be of interest to most collectors – but to micromounters and systematic mineral collectors, this site is probably of tremendous interest. There are, of course, a great many mineral species from the site for which it is not the type locality.

For a quality writeup of the site and more information I highly recommend the ‘Forschungsgemeinschaft Lengenbach’ website linked below – it belongs to the Lengenbach Research Association, a group which studies the site.

The MDPI gives us a little information on the modern history of the site, too, naming a series of non-profit exploitations of the quarry in recent years:

• 1958 – 1997: The Arbeitsgemeinschaft Lengenbach extracted over 28,000 specimens from the site.
• 1998 – 2002: The Interessengemeinschaft Lengenbach extracted over 2400 specimens from the site.
• 2003 – present: The Forschungsgemeinschaft Lengenbach has found 43 new mineral species from the site, including at least 17 new type locality minerals (as of 2018).
