Arcanite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
K2SO4
System:
Orthorhombic
Colour:
Colourless, white
Hardness:
2
Name:
Named in 1845 by Wilhelm Carl von Haidinger from the Latin "arcanum duplicatum," for double secret, a medieval alchemical name. The original material was an exudate on the surface of discarded railroad track ties that had been used in the Santa Ana tin mine, Trabuco Canyon, Santa Ana Mountains, Orange County, California, USA.
Arcanite-Mascagnite Series

This species was described and named based on artificial material and the type occurrence, which is anthropogenic (pine rail tie in a mine). It has since been identified in nature.

Classification of Arcanite

Valid - first described prior to 1959 (pre-IMA) - "Grandfathered"
7.AD.05

7 : SULFATES (selenates, tellurates, chromates, molybdates, wolframates)
A : Sulfates (selenates, etc.) without additional anions, without H2O
D : With only large cations
28.2.1.2

28 : ANHYDROUS ACID AND NORMAL SULFATES
2 : A2XO4
25.1.4

25 : Sulphates
1 : Sulphates of the alkali metals and ammonium
