Creaseyite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pb2Cu2Fe3+2(Si4.67Al0.33)O15.33(OH)3 · H2O
Crystal System:
Orthorhombic
Name:
Named in 1975 by Sidney A. Williams and Richard A. Bideaux for Dr. Saville Cyrus Creasey (1917 - ) economic geologist, U.S. Geological Survey, in recognition of his geological studies on Arizona localities, particularly the Mammoth-St. Anthony mine.
Visually very similar to green-coloured minerals of the Mixite Group, especially Agardite.
