AB The Cala iron deposit has been traditionally regarded as a classic iron skarn developed on Cambrianlimestone adjacent to a Variscan monzogranitic stock. Ongoing studies show that the geologic setting ismore complex and the mineralization is replacive on marble and calcsilicate and pelitic hornfels andcontrolled by syntectonic hydrothermal activity with a pull-apart structure. The skarn only forms a part ofthe hydrothermal alteration. Most of the magnetite is related to an biotite-quartz-ankerite-chloriteassemblage, while the pyrite-chalcopyrite ore seems to be slightly younger, replacing magnetite alongextensional structures, sharing many features with the IOCG style of mineralization
