Pb2Cu2Fe3+2(Si4.67Al0.33)O15.33(OH)3 · H2O
Crystal System:
Named in 1975 by Sidney A. Williams and Richard A. Bideaux for Dr. Saville Cyrus Creasey (17 July 1917, Portland, Oregon, USA - 19 December 2000) 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.
