Abstract

The aim of the study is the determination of mineralogical and geochemical features of magnetite from massive sulfide and iron deposits to develop forecasting criteria of ore objects. The layered magnetitolites of sulfide (Mauk, Letnee, Sibai, and Molodezhnoe) and stratiform iron (Kachar, Sarbai, Estyuninskoe, Osokino-Aleksandrovskoe, and Techenskoe) deposits of volcanosedimentary association are the objects of study. Using laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) it was established, that, in contrast to magnetite of iron deposits, magnetite of ore-controlling volcanosedimentary horizons of the Urals massive sulfide deposits is characterized by a higher content and stable associations of Bi, Te, Co, As, Cd, Zn, Cu, and Mo due to relict inclusions of sulfide clasts and products of their halmyrolysis. The elevated Ti, V, and Zr contents, as well as the mixed associations of lithophile, siderophile, and chalcophile elements, are more typical of magnetite of iron deposits after hyaloclastites. Typochemistry of magnetite from volcanosedimentary horizons can be a criterion for searching the massive sulfide deposits.
