In these cavities many other sulfosalts have been found: guettardite, robinsonite, zinkenite, boulangerite, semseyite, jordanite, tetrahedrite, sulvanite, colusite, famatinite and kesterite.
Associated minerals are: jordanite, galena and pyrite; less commonly with sphalerite, lengenbachite and hatchite.
The mineralization consisted of patches, grains and intergrowths of argentite/acanthite, proustite, xanthoconite, smithite, miargyrite, argyrodite, unidentified bismuth sulfosalts (Gasparrini, 1978), jordanite, pyrargyrite and gersdorffite (Taylor, 1984).
A report of geocronite, as grains up to 200 microns (Zakrzewski, 1989), gives analyses with As[greater than]Sb so the mineral should actually be jordanite and is listed as such in the table.
How about sphalerite and jordanite from Lengenbach, Switzerland, on the same specimen?
In the third stage, conversion of lead-beating minerals to jordanite, replacement of copper-bearing minerals by tetrahedrite, and deposition of pearceite and proustite took place.
