Dump from the Kjennerudvann Silver mine, the typelocality of anthophyllite.

Note on the typelocality of anthophyllite:
Schumacher (1801) first described anthophyllite from the Kongsberg area ("in der Gegend von Kongsberg"). The locality was for many years kept as a secret until Möller (1825) gave new and more exact information on the locality, "in a dump from an old prospect at Kjennerudvannet" ("i en Berghald af et gammelt Skjerp ved Kjernerudvandet"). This has been interpreted by collectors and mineralogist to be the amphibole prospect at the shore of Kjennerudvannet lake. However Kullerud et al. (2019) has pointed out that the most likely locality is the dumps of the old silver mine at Kjennerudvann Lake (see also Raade 1996).
Remnants of a orthoamphibole rocks has been found in Kjennerudvann Silver Mine and at the dumps. This rock is visually similar to the one quarried at the amphibole prospect, and is characterized by up to laths of light green-brown amphibole in a darker gren matrix.
Analysis of one sample of anthophyllite (the laths in the orthoamphibole rock) from Kjennerudvann has shown this not to be anthophyllite, but gedrite/sodic gedrite. Further investigations is in progress to establish if anthophyllite exist at the typelocality or not (Kullerud et al. 2019).
