Babingtonite has been found at El Valle-Boinás Cu-Au deposit, Spain, this being the first known occurrence of this mineral in skarn in Spain. It is a locally abundant accessory mineral related to the hydrothermal alteration of the calcic skarn. Babingtonite is present in metasomatized aplitic dykes or occurs as a consequence of alteration of Fe-rich end members of both hedenbergite and andradite and always in association with Fe-rich epidote (Ps32–48). Other related minerals are calcite, quartz, hydroxyapophyllite, hydroandradite, prehnite, pumpellyite-(Fe+2), Cu-sulphides and electrum. The babingtonite formation is related to the locally Aldepleted aqueous fluids at relative high fO2 and low XCO2.
