Aegirine-Bearing Clinopyroxenes in Granulite Xenoliths from the Udachnaya Kimberlite Pipe, Siberian Craton: Comparison of the Mössbauer and Micropobe Data
The aegirine end-member (NaFe 3+ Si 2 O 6 ) in clinopyroxenes resulted from incorporation of Fe 3+ into the mineral structure. Its presence affects the...

Influence of Trap Magmatism on the Oil and Gas Potential of Sedimentary Deposits
The depletion of hydrocarbon reserves in the known traditional structural traps leads to an increase in the share of so-called hard-to-recover or... -
Correlation of High-Calcium Silica-Undersaturated Complex of the Maymecha–Kotuy Province with Siberian Flood Basalts: New Age Data on the Kugda Massif (Polar Siberia)
Abstract —Perovskite crystals from the ore-bearing olivinite and phoscorite of the Kugda massif were analyzed by LA-ICP-MS. Age obtained for the...
