Woodhouseite

Woodhouseite belongs to the beudantite group AB3(XO4)(SO4)(OH)6 where A = Ba, Ca, Pb or Sr, B = Al or Fe and X = S, As or P. Minerals in this group are isostructural with each other and also with minerals in the crandallite and alunite groups. They crystallise in the rhombohedral system with space group Rm and crystals are usually either tabular or pseudo-cubic to pseudo-cuboctahedral.
Woodhouseite was named after Professor Charles Douglas Woodhouse〔http://content.cdlib.org/view?docId=hb1199n68c&doc.view=frames&chunk.id=div00099&toc.depth=1&toc.id=&brand=calisphere〕 (1888–1975), an American mineralogist and mineral collector from the University of California, Santa Barbara, USA, and one-time General Manager of Champion Sillimanite, Inc.
== Environment ==
Woodhouseite is a secondary mineral found where wall rock alteration occurred in hydrothermal and disseminated ore deposits; rare in cave deposits, formed from guano. At the type locality it occurs in vugs in quartz veins in an andalusite, Al2OSiO4, deposit. This is in pre-Cambrian meta-quartzite that has been intruded by late Jurassic granitic rocks. Woodhouseite is found only near masses of lazulite, MgAl2(PO4)2(OH)2.
Associated Minerals at the type locality include topaz, Al2SiO4F2, quartz, SiO2, augelite, Al2PO4(OH)3, lazulite, MgAl2(PO4)2(OH)2, tourmaline, baryte, BaSO4, muscovite, KAl2(Si3Al)O10(OH)2, and pyrophyllite, Al2Si4O10(OH)2, all of which formed before the woodhouseite, which is a late-forming mineral.〔Lemmon, Dwight M (1937) American Mineralogist 22:939-948〕
