Santabarbaraite

Santabarbaraite

Named for the type locality at the Santa Barbara mining district in Tuscany, Italy, where it is found in concretionary nodules in clay in a lignite-bearing basin. Other known localities include in the Iron ore deposits on the Kerch peninsula in Ukraine, in the clays overlain by Pleistocene basalts at Wannon Falls near Hamilton in Victoria, Australia, and others in Cameroon and Germany. Santabarbaraite appears as brown to light brown amorphous masses, or as vivianite crystal and aggregate pseudomorphs. Santabarbaraite is a product of the oxidation of vivianite through metavivianite.
