Arendalite (of Blumenbach)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
{Ca2}{Al2Fe3+}(Si2O7)(SiO4)O(OH)
Name:
Named after the locality: Arendal iron mines, Norway.
The name was originally introduced by Blumenbach (1799) (or Abildgaard?) and used by Karsten (1800) for the same mineral that d'Andrada (1800) named Acanthicone.
A variety of Epidote

A variety of epidote from the Arendal iron mines in Norway, which occurs in well-developed green crystals.

The history of the mineral name is interesting:
The name "Arendalit" seems to appear first in Blumenbach (1799). It may have been coined by the Dane Peter Christian Abildgaard around 1800. One year later, it appears in Karstens (1800). "Arendalit" referred to large six-sided greenish crystals that were found at the Arendal iron mines, Norway (thus the name Arendalite). These were first described in 1794 by Widenmann as "Ein noch unbekanntes Fossil [Another unknown fossil]", but given no name by him. Abildgaard sent some samples to the French mineralogist Haüy who responded that it was related to thallite (of Delamétherie 1792). Later, Abildgaard (1801) described the mineral as "arendalischen thalit, oder der sogennannten Arendalit". Samples from Arendal were among the samples Haüy studied when he coined the name epidote, and he described the epidote from Arendal as "le plus parfaits que j'ai observés [the most perfect ones I have observed]".

* Karsten (1800) is cited in various books, but he refers to Blumenbach (1799) who, in turn, refers to an analysis in Gmelin (1798).
