Destinezite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe23+(PO4)(SO4)(OH) · 6H2O
System:
Triclinic
Colour:
Yellow, brownish yellow, ...
Hardness:
3 - 4
Name:
Named in H. Forir and A. Jorissen in 1880 in honor of Mr. Pierre Destinez [d. ~1910 or slightly earlier], a laboratory assistant at the University of Liège, Liège, Belgium. Destinez was a member of Société Géologique de Belgique as early as 1886 and published a number of articles on paleontological subjects as late as 1904.
Sanjuanite-Destinezite Group.

Destinezite was redefined (IMA Code 00-E) as triclinic Fe2(PO4)(SO4)(OH).6H2O, the crystalline counterpart of the amorphous diadochite.

Structurally related to arangasite.

Classification of Destinezite
