Research subject . The Tessemsky granite massif is located in the North Taimyr tectonic zone, surrounded by Cambrian rocks. Pekinsky within Central metamorphosed Proterozoic Aim To develop a methodology for using composition of accessory granitoid minerals when prospecting Cu-Mo-Au-porphyry mineralization on example and massifs Peninsula. Materials methods Accessory zircon apatite contained two samples from (P1, P2) (T2, T3) were studied. Their mineral was examined an EPMA Cameca SX100...
Mesozoic (125–135 Ma) cratonic low-Ti lamproites from the northern part of Aldan Shield do not conform to typical classification schemes ultrapotassic anorogenic rocks. Here we investigate their origins by analyzing olivine and olivine-hosted inclusions Ryabinoviy pipe, a well preserved lamproite intrusion within Shield. Four types are identified: (1) zoned phenocrysts, (2) high-Mg, high-Ni homogeneous macrocrysts, (3) high-Ca low-Ni (4) mantle xenocrysts. Olivine compositions comparable...
Inductively coupled plasma mass spectrometry (ICP-MS) and laser ablation (LA) are widely used to study the trace element composition of minerals, including silicates; nevertheless, methodological activities in this area aimed at increasing sensitivity locality reducing error, remain relevant. The paper describes approaches for studying a number silicate minerals using NexION 300S quadrupole ICP-MS with an NWR 213 LA attachment, obtained on standard synthetic glasses NIST SRM 612 610, as well...
Abstract The chemical composition of 42 samples raw glass from the Komarov settlement on Middle Dniester was studied by means SEM-EDS, EPMA and LA-ICP-MS analyses. We singled out groups colourless Levantine Egyptian origin, chronology which indicates that workshop could be dated to 4 th – early 5 century. data do not confirm glassmaking industry existed here in an earlier period, as previously believed. manufacturing combines use high-quality perfectly decolourized with intensive cullet,...
Relevance. In the basin of r. Pishma subvolcanic formations, localized in fields spreading Middle Devonian Rudyanskaya sequence, are presented by different on composition small bodies, sills and dykes, forming with volcanogenic rocks sequence a basalt-andesite-rhyolite complex, formation which is associated volcanic activity, that took place environments close to modern island arcs. Their isotope dating geochemical characteristic rather relevant for specification composition, volume...
Research subject . Zircon grains from diamond placers of the Molodo and Ebelyakh rivers Yakut Arctic. Aim To study indicator characteristics zircon to determine sources diamonds ways their transfer placers; analyze optical-spectroscopic isotope-geochemical parameters grains, microelemental, U-Pb, Lu-Hf isotope composition. Materials methods A LA-ICP-MS analysis U-Pb isotopic trace element composition was carried out using a NexION 300S mass spectrometer with an NWR 213 attachment. An system...
The Taimyr Peninsula in the Russian High Arctic comprises a late Paleozoic-early Mesozoic collisional belt where several porphyry-type mineralization occurrences were identified during last decade, making this area potential exploration target for Cu-Mo deposits. In order to further evaluate metallogenic of poorly outcropped northeastern part Taimyr, samples from seven granitoid intrusions investigated study aimed granite fertility based on petrography, geochemistry, and composition porphyry...
The first U-Pb dating of detrital zircon from chromite sandstones the Middle Permian Sabantuy paleoplacer, localized in Southern Pre-Urals, has been obtained. distribution dates is unimodal with a peak at 420–400 Ma. Two-thirds all ages are Devonian, and more than half them correspond to Early during which supra-subduction ophiolitic accompanying high-pressure metamorphic complexes were formed Urals, ultramafic-mafic magmatism was occurred. These spatially combined geological bodies exposed...
The article presents a summary and review of the studies carried out at “Geoanalitik” shared research facilities IGG UB RAS for period 2019–2024 years on development implementation an integrated approach to study chemical isotopic composition, structure properties minerals with high spatial resolution (or performed micro-samples substance) based various techniques in field electron probe microanalysis microscopy, solid-state spectroscopy, X-ray fluorescence, mass spectrometry atomic...

Results. (1) X-ray photoelectron was used to study radiationinduced short-range order destruction metamictised zircons; (3) low-temperature boson peak Raman stresses...
Relevance of the work. The Iset river basin contains most extensive outcrops volcanogenic formations Beklenishchevsky complex East Ural megazone, age which is determined as Early Carboniferous by ratio volcanic rocks with faunistically characterized sedimentary deposits. Volcanics here compose flows andesite-basaltic and andesitic lavas lava breccias. There are no geochronological dates specifying rocks, makes it difficult to assess their role in formation megazone. Therefore, isotopic...

A technique of analyzing the isotopic composition Lu and Hf for determining Lu/Hf Hf/Hf ratios in zircons is presented using a Neptune Plus (Thermo Scientific) mass spectrometer with inductively coupled plasma an NWR 213 (ESI) laser ablation attachment. On example Mud Tank, GJ-1, 91500, Plesovice Temora-2 standard zircon samples, uncertainty single measurement 176Hf/177Hf ratio has been obtained range 0.002-0.008% form 2σ (with crater diameter 50 μm; when it decreased to 25 μm increased by...
Crystalline continental crust of the northern East European platform, particularly within Arkhangelsk diamondiferous province (ADP), is covered by sedimentary rocks, and no direct samples are available. Scarce data on age evolution based upon studies lower-crustal xenoliths (Koreshkova et al., 2014; Shchukina 2018). In order to obtain more information ADP we study a set 135 zircon xenocrysts selected from heavy minerals fraction V. Grib kimberlite. Zircons between 100 250 micron in size...

<p><strong>Introduction</strong>. Two structural zones are traditionally distinguished in the Eastern Urals. They Magnitogorsk zone and East Ural zone, which divided by a narrow suture. The Early Sudetian (Visean) orogenic phase is marked unconformity base of Upper Visean terrigenous-carbonate sequence both suture zone. According to drilling data granitic-pebble-bearing conglomerates present at this sequence. rearrangement implied end rifting...
