Named after Professor Charles Douglas Woodhouse (1888-1975), American Mineralogist and mineral collector, University of California, Santa Barbara, California, USA.
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.
