The mineralization on the Erzmatt could be an example of a geochemical anomaly similar to the famous Lengenbach deposit (Switzerland) before the metamorphic overprint at Lengenbach. Corresponding...

...) at the famous sulphosalt locality Lengenbach in Binntal, Switzerland, where it occurs in a dolomitic rock of Triassic age, in close association with various Pb-As-sulphosalts (mainly rathite). It forms extremely fine needles reaching up to a maximum length of about 0.3 mm. The needles are elongated along...

This fact is reflected in the various new Tl-sulfosalts from Lengenbach reported in the past 15 years (e.g., edenharterite, jentschite, erniggliite, stalderite, bernardite, sicherite). Knowing this, it is understandable why the above...
