Publikováno v: Geological and Geo-Environmental Processes on Earth ISBN: 9789811641213
Studying early Precambrian astroblems is complicated by their localization in structural and compositional complexes that underwent superimposed metamorphism and tectonic processing. Back in the 1980s, seven sites with occurrences of breccias and oth

Reconstruction of the Neoproterozoic–Cambrian Orogenesis in Princess Elisabeth Land (East Antarctica) from a Study of Granitic Rocks
Autor: N. A. Gonzhurov, N. V. Borovkov, S. A. Svetov, E. V. Mikhal’skii, E. L. Kunakkuzin, M. A. Gogolev
Publikováno v: Geotectonics. 52:421-446
Abundant Cambrian granitic rocks in Princess Elizabeth Land and adjacent regions of Antarctica occupy various positions (from syn- to postkinematic) in the structure of the crust. Their mineral and isotopic composition reflects both the character and

Raman spectra of impact zircons in the Jarva-varaka layered massif (the Monchegorsk ore region, the Kola Peninsula)
Autor: V. N. Bocharov, T. V. Kaulina, L. M. Lyalina, V. L. Il'chenko, I. A. Kasatkin, L. I. Nerovich, E. L. Kunakkuzin
Publikováno v: Vestnik MGTU, Vol 20, Iss 1/1, Pp 72-82 (2017)
Zircon crystals from granophyre norites of the Jarva-varaka massif of the Monchegorsk ore region (the Kola Peninsula) have been studied by means of back-scattered electron (BSE) imaging and Raman spectroscopy. The Jarva-varaka massif according to geo

Low-grade Sandow Group metasediments of the Denman Glacier area (East Antarctica): Chemical composition, age and provenance from U–Pb detrital zircon data, with some palaeotectonic implications
Autor: Sergey G. Skublov, E. L. Kunakkuzin, D. A. Tkacheva, N.V. Rodionov, I. N. Kapitonov, E.V. Mikhalsky, G.L. Leitchenkov
Publikováno v: Polar Science. 26:100587
The Sandow Group in the Denman Glacier area consists of low-grade supracrustal (post-cratonic) strata. Such rocks are scarce and poorly studied in East Antarctica, but are significant for a better understanding of the geological history and tectonic

The Kandalaksha-Kolvitsa gabbro-anorthosite complex: Nd-Sr isotope-geochronological evidence of its affinity to the East-Scandinavian Large Igneous Province
Autor: E. N. Steshenko, T. B. Bayanova, N. A. Ekimova, P. A. Serov, E. L. Kunakkuzin
Publikováno v: IOP Conference Series: Earth and Environmental Science. 539:012160
The article provides new Sm-Nd and Nd-Sr isotope-geochronological data on rocks of the Paleoproterozoic Kandalaksha-Kolvitsa gabbro-anorthosite complex. The isotope Sm-Nd dating on metamorphic minerals (apatite, garnet, sulfide) and rock of the Kolvi

The paleoproterozoic Monchetundra mafic massif (Kola Peninsula): New geological and geochronological data
Autor: E. L. Kunakkuzin, Elena Borisenko, L. I. Nerovich, Tamara B. Bayanova
Publikováno v: Doklady Earth Sciences. 465:1107-1111
In view of the absence of an unambiguous intrusive contact between the main mafic rocks varieties in the Monchetundra massif, the latter was considered for a long time as a large complex of syngenetic mafic rocks. On the basis of data derived from st

Paleoproterozoic layered PGE-bearing Monchetundra pluton, Kola Peninsula: Sm–Nd age of metamorphic alteration of mafic rocks
Autor: Elena Borisenko, Pavel Serov, E. L. Kunakkuzin, Tamara B. Bayanova, L. I. Nerovich
Publikováno v: Doklady Earth Sciences. 464:885-888
The aim of this work is Sm–Nd study of metamorphic alteration of massive gabbronorites from the Monchetundra pluton. The mafic rocks of the pluton are unevenly metamorphosed up to amphibolite facies with the formation of garnet, hornblende, and oth
