At the type locality, the Cap Garonne Mine, Le Pradet, Var, Provence-Alpes-Côte d'Azur, France, pushcharovskite is a very rare secondary mineral from the oxidised zone of a polymetallic hydrothermal base metal deposit. It occurs as colourless to light green tufts and acicular, radial fibrous aggregates to 1 mm in diameter. Associated minerals include tennantite, covellite, geminite, lindackerite, yvonite and mahnertite, arsenopyrite, bismuth, chalcopyrite and quartz (AM 84.196-197, HOM, Mindat).
