Whelanite


Whelanite is a copper calcium silicate carbonate. The mineral name honors James A. Whelan (19282003), mineralogy professor at the University of Utah. Kampf et al. (2012) published the first description of whelanite, 35 years after its species proposal was submitted to the International Mineralogical Association.

Whelanite here forms sky blue plates, in aggregates at the base of tufts of white tobermorite needles. The matrix is a garnet skarn. Whelanite is not especially common at the Christmas mine, compared to dioptase and kinoite.
