Name:
Named in honor of Charles Douglas Woodhouse (1 May 1888, Burlington, Vermont, USA - 5 August 1975, Santa Barbara, California, USA), mineralogist, mineral collector, and professor at the University of California, Santa Barbara, California, USA. He discovered it.
The Ca analogue of svanbergite.
A secondary mineral found where sulphatic argillic wall rock alteration occurred in hydrothermal and disseminated ore deposits; rare in cave deposits.
