Heterosite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Fe3+,Mn3+)PO4
System:
Orthorhombic
Colour:
Untreated mineral is ...
Hardness:
4 - 4½
Name:
Named in 1826 by François Alluaud (II) from the Greek έτερος for "another", probably in allusion to the species being the second new mineral containing iron and manganese from the same locality.
Triphylite Group, Heterosite-Purpurite Series.

The species of this series are secondary minerals formed by oxidation of iron and or manganese with the simultaneous leaching of lithium from primary phosphates (precursors), usually lithiophilite or triphyllite. Intermediate alteration products are part of a continuous process of alteration: ferrisicklerite and sicklerite, with Grandfather status, but may not be valid. The Fe:Mn value has not been observed to vary much from the primary triphylite to the secondary heterosite. Heterosite is frequently artificially coloured bright purple through acid treatment.

Classification of Heterosite
