Conditions of Formation of Layered Intrusions of the Monchegorsk Magmatic Cluster
Petrology - Tập 30 - Trang 369-391 - 2022
V. S. Semenov, O. V. Kazanov, S. I. Korneev, E. B. Salnikova, S. V. Semenov
The paper presents geochronological data and results of petrological modeling of the Monchegorsk and Monchetundra layered massifs. The U-Pb ID-TIMS zircon dating of norite from the marginal zone of Mt. Nittis yielded 2506 ± 7 Ma, which coincides with previous data on similar rocks from other areas. Based on the comparison of sections of the Monchegorsk and Kivakka massifs, the pre-erosion thicknes...... hiện toàn bộ
Processes of Replacement by Melt at Interaction between Refractory Materials and Industrially Produced Melts
Petrology - Tập 26 Số 4 - Trang 428-446 - 2018

Distinctive petrological, geochemical, and geodynamic features of subduction-related magmatism
Petrology - Tập 18 - Trang 84-106 - 2010
N. L. Dobretsov
Geological-petrological and geochemical data on subduction-related magmatism (including the volumes and compositions of the corresponding magmatic series) are compared to the results of experiments and numerical simulation. The subduction zone is subdivided into five depth sectors and volcanic zones I, II, and III: 1 is the accretionary wedge that controls the geodynamic stability of subduction; 2...... hiện toàn bộ
Melt inclusions in olivine phenocrysts in unaltered kimberlites from the Udachnaya-East pipe, Yakutia: Some aspects of kimberlite magma evolution during late crystallization stages
Petrology - Tập 15 - Trang 168-183 - 2007
A. V. Golovin, V. V. Sharygin, N. P. Pokhilenko
The results of a complex study of melt inclusions in olivine phenocrysts contained in unaltered kimberlites from the Udachnaya-East pipe indicate that the inclusions were captured late during the magmatic stage, perhaps, under a pressure of <1 kbar and a temperature of ≤800°C. The inclusions consist of fine crystalline aggregates (carbonates + sulfates + chlorides) + gas ± crystalline phases. Mine...... hiện toàn bộ
Indian MORB-type mantle beneath the Kuril Island arc: Isotopic investigation of the mafic lavas of Kunashir Island
Petrology - Tập 20 Số 1 - Trang 93-100 - 2012
Yu. A. Martynov, Jun‐Ichi Kimura, A. Yu. Martynov, А. В. Рыбин, M. Katakuse
Determining the Geodynamic Setting of Adakitic Granitoids Using Geochemical Data
Petrology - Tập 26 - Trang 255-264 - 2018
S. D. Velikoslavinskii, A. B. Kotov, D. P. Krylov, A. M. Larin
Discriminant analysis was performed for representative sets of igneous rocks with adakitic geochemical signatures (granitoids of Archean tonalite–trondhjemite–granodiorite suites, island-arc adakites, and adakites and adakitic granitoids of collisional to postcollisional geodynamic settings). It was shown that the granitoids of Archean tonalite–trondhjemite–granodiorite suites are significantly di...... hiện toàn bộ
Visual in-situ monitoring of the behavior and phase states of water-hydrocarbon inclusions at high temperatures and pressures
Petrology - Tập 19 - Trang 653-674 - 2011
V. S. Balitsky, S. V. Penteley, L. V. Balitskaya, M. A. Novikova, T. M. Bublikova
Experiments aimed at examining interactions between hydrothermal solutions and caustolithic rocks, oil, and its major fractions were carried out to obtain model water-hydrocarbon fluids (WHCF) and study their behavior and phase states at high P-T parameters. Simultaneously we experimentally synthesized and grew quartz crystals with inclusions as the major source of information on the behavior and ...... hiện toàn bộ
Metasomatized Xenoliths of Mantle Eclogites and Garnet Pyroxenites from the V. Grib Kimberlite, Arkhangelsk Province
Petrology - - 2022
N. M. Lebedeva, A. A. Nosova, L. V. Sazonova, Y. O. Larionova
We investigated mantle eclogite and garnet pyroxenite xenoliths from the V. Grib kimberlite located in the Arkhangelsk diamond province. The eclogites in the lithospheric mantle beneath the Arkhangelsk province were strongly modified by metasomatic processes, which totally obliterated the primary features of protolith. Detailed studies of the xenoliths allowed us to distinguish the following metas...... hiện toàn bộ
Abdar-Khoshutula intrusive-dike series: Evolution and origin of granitoids in Early Mesozoic magmatic area (Central Mongolia)
Petrology - Tập 24 - Trang 497-511 - 2016
V. S. Antipin, D. Odgerel
The dike belt and separate intrusive bodies of the Abdar–Khoshutula series were formed in the NE-trending linear zone, southwest of the Daurian–Khentei batholith, in the peripheral part of the Early Mesozoic magmatic area, on the western termination of the Mongol–Okhotsk belt. The granitoids of this series are subdivided into following geochemical types: anatectic granitoids of the calc-alkaline a...... hiện toàn bộ
P-bearing Olivines from the “Luna-20” Soil Samples, Their Sources and Possible Phosphorus Substitution Mechanisms in Lunar Olivine
Petrology - Tập 26 - Trang 314-327 - 2018
S. I. Demidova, T. Ntaflos, F. Brandstätter
Rocks with P-bearing olivine were found in soil samples delivered by the “Luna-20” automated station. They are ascribed to the highland anorthosite–norite (more rarely, gabbro-norite)–troctolite rock series enriched in phosphorus and other incompatible elements, but are not related to typical KREEP rocks enriched in incompatible elements. Their source is presumably of hybrid origin and related to ...... hiện toàn bộ
