Global implication of mesoproterozoic (~ 1.4 Ga) magmatism within the Sette-Daban Range (Southeast Siberia)
Autor: Sergey V. Malyshev, Alexei V. Ivanov, Andrey K. Khudoley, Alexander E. Marfin, Vadim S. Kamenetsky, Maya B. Kamenetsky, Olga Yu. Lebedeva
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-10 (2021)
Abstract Mesoproterozoic period included several global tectonic events like break-up of Nuna and formation of Rodinia. However, although Siberia is a significant piece of both supercontinents, Mesoproterozoic time is marked by quiescence of magmatic

Publikováno v: Geology. 49:1312-1316
The origins of many supergiant ore deposits remain unresolved because the factors responsible for such extreme metal enrichments are not understood. One factor of critical importance is the timing of mineralization. However, timing information is com

Polymineralic inclusions in kimberlite-hosted megacrysts: Implications for kimberlite melt evolution
Autor: Karsten Goemann, D. Graham Pearson, Marina A. Gornova, Igor S. Sharygin, Alexander V. Golovin, Maya B. Kamenetsky, Vadim S. Kamenetsky, Adam Abersteiner
Publikováno v: Lithos. :310-325
Megacrysts are large (cm to >20 cm in size) mantle-derived crystals, which are commonly entrained by kimberlite magmas, comprising of olivine, orthopyroxene, clinopyroxene, phlogopite, garnet, ilmenite and zircon as common phases. Numerous studies ha

Composition and emplacement of the Benfontein kimberlite sill complex (Kimberley, South Africa): Textural, petrographic and melt inclusion constraints
Autor: Adam Abersteiner, Vadim S. Kamenetsky, Karsten Goemann, Montgarri Castillo-Oliver, Jay Thompson, Maya B. Kamenetsky, AR Cherry, Geoffrey H. Howarth, Andrea Giuliani
Publikováno v: Lithos. :297-314
The Benfontein kimberlite is a renowned example of a sill complex and provides an excellent opportunity to examine the emplacement and evolution of intrusive kimberlite magmas. We have undertaken a detailed petrographic and melt inclusion study of th

Implication of Mesoproterozoic (∼1.4 Ga) magmatism within Sette-Daban (Southeast Siberia)
Autor: Sergey V. Malyshev, Maya B. Kamenetsky, Andrey K. Khudoley, Alexei V. Ivanov, Vadim S. Kamenetsky
Numerous Mesoproterozoic mafic dyke swarms are known in Siberia. The main intrusions are concentrated in the northern part of the platform and in Sette-Daban (southeastern part of Siberia), and single intrusions are known on all the outcrops of the c

Polymineralic inclusions in oxide minerals of the Afrikanda alkaline-ultramafic complex: Implications for the evolution of perovskite mineralisation
Autor: Naomi J. Potter, Anton R. Chakhmouradian, Thomas Rodemann, Maya B. Kamenetsky, Karsten Goemann, Vadim S. Kamenetsky
Publikováno v: Contributions to Mineralogy and Petrology. 175
The exceptional accumulation of perovskite in the alkaline-ultramafic Afrikanda complex (Kola Peninsula, Russia) led to the study of polymineralic inclusions hosted in perovskite and magnetite to understand the development of the perovskite-rich zone

Precise geochronological constraints on the origin, setting and incorporation of ca. 1.59 Ga surficial facies into the Olympic Dam Breccia Complex, South Australia
Autor: Vadim S. Kamenetsky, Jocelyn McPhie, Kathy Ehrig, AR Cherry, James L. Crowley, Maya B. Kamenetsky
Publikováno v: Precambrian Research. 315:162-178
The Olympic Dam Breccia Complex (host to the Olympic Dam Cu-U-Au-Ag deposit) is derived largely from granite (Roxby Downs Granite) but includes clasts and domains derived from surficial facies (felsic volcanic rocks and bedded clastic facies). New hi

Was Crustal Contamination Involved in the Formation of the Serpentine-Free Udachnaya-East Kimberlite? New Insights into Parental Melts, Liquidus Assemblage and Effects of Alteration
Autor: Maya B. Kamenetsky, Adam Abersteiner, Karsten Goemann, Alexander V. Golovin, Vadim S. Kamenetsky
Publikováno v: Journal of Petrology. 59:1467-1492
The petrologically unique Udachnaya-East kimberlite (Siberia, Russia) is characterised by unserpentinised and H2O-poor volcaniclastic and coherent units that contain fresh olivine, along with abundant alkali-rich carbonates, chlorides, sulphides and
