This is an interesting association from Sidi Ayat, Aouli, Morocco. The bladed baryte crystals are accompanied by 1cm cubes of fluorite and thinly coated by an iron oxide. On top of the brown-coated crystals is a fuzzy coating of fibrous malachite. These oxide-coated, barite-fluorite combo specimens are hard to come by with none listed on mindat at the time of this posting!
