Autor: Vasiliy O. Yapaskurt, Igor V. Pekov, A. V. Pakunova, D. A. Khanin, I. A. Ekimenkova

Publikováno v: Moscow University Geology Bulletin. 71:330-336

Based on the results of more than 600 electron microprobe analyses of 25 minerals the distribution pattern of the Cr6+ impurity in vanadates, phosphates, and arsenates collected in oxidation zones of six ore deposits of the Urals was studied. Among t

Crystal structure of litvinskite: A new natural representative of the lovozerite group

Autor: Yu. K. Egorov-Tismenko, I. A. Ekimenkova, Natalia A. Yamnova, Igor V. Pekov

Publikováno v: Crystallography Reports. 46:190-193

A new representative of the lovozerite group—Na, Zr, Mn-silicate litvinskite (Na, H2O, □) 3(□, Na, Mn2+)Zr[Si6O12(OH)3(OH, O)3]—was discovered in ultraagpaitic pegmatites from the Lovozero massif. The crystal structure of the mineral was solv
