List of Official L-Numbers

Each specimen mined in the Lengenbach quarry is examined with a stereomicroscope, trimmed further if necessary, and visually identified. Specimens of special scientific interest are put aside for further investigations by preferred associated scientists (PAS).

Specimens kept for annual distribution among the members of the association are assigned an official L-number ("L" for Lengenbach). The system by which those numbers have been assigned changed over the years and with each Lengenbach syndicate.

We list here an overview of those L-numbers, to provide a mean to check in which year a specific official sample one might have in collection has been found in the Lengenbach quarry.
