Abstract

Summary

Columbite samples from the quarry No.2 of the Volodarsk-Volyn piezoelectric quartz deposit were investigated. Chemical data revealed a tungsten admixture, chemical heterogeneity of the peripheral zone of one of the columbite crystals, and allowed the separation of a new mineral for Ukraine - qitianlingite, which is a complex oxide of manganese, iron, tantalum, niobium, and tungsten, which forms the inclusion in the peripheral zone of the columbite crystal. In addition, an unknown silicate-tantalum phase with impurities of uranium, which was formed during the last stages of columbite growth or after its growth, and developed in the interstitium between columbite and qitianlingite, was detected.
