Trace element distribution and crystal morphology of perovskite from garnet-vesuvianite skarn of the Akhmatovskaya mine and chlorite-perovskite-calcite veins of the perovskitovaya mine (South Urals) were studied using LA-ICp-MS. perovskite from the Akhmatovskaya mine has low contents of REEs and high contents of Si, Al, Zr and fe. perovskite from the perovskitovaya mine is enriched in REEs. The diferent contents of trace elements refects distinct formation conditions of minerals. perovskite from the perovskitovaya mine are characterized by regular decrease in REE content from early, relatively high-temperature crystals to late ones.
