Abstract In this study, we discuss mineral chemistry data, melt inclusion study results, and report Ar–Ar phlogopite age for the aillikite dikes of Arbarastakh alkaline-carbonatite complex on Aldan-Stanovoy shield, Russia. Aillikite was crystallized at 631 ± 8.5 Ma, coeval with intrusion rocks. The formed during late Neoproterozoic epoch rare earth element-Nb ore-bearing magmatic activity that widespread southwestern southern margins Siberian craton, related to rifting processes breakup...
Geochronological studies have been made on the main types of rocks from Burpala alkaline massif and two gabbro gabbro-diorite dikes located nearby. U-Pb LA-SF-ICP-MS zircon geochronology for yielded a date 294±2 Ma crystallization, 607±4 diorite 298±2 296±2 melanocratic nepheline syenite crustallization, 291±2 293±3 quartz quartz-containing granite crystallization. The stage formation (298–291 Ma) coincides with period Synnyr pluton some complexes Vitim segment Transbaikalia confirms...
The mineral composition and melt inclusions of ultramafic lamprophyres the Terina complex were investigated. rocks identified aillikites, mela-aillikites, damtjernites, they originally composed olivine macrocrysts phenocrysts, as well phlogopite phenocrysts in carbonate groundmass, containing phlogopite, clinopyroxene feldspars. Minor accessory minerals fluorapatite, ilmenite, rutile, titanite, sulphides. Secondary quartz, calcite, dolomite, serpentine, chlorite, barite, synchysite-(Ce),...
Ultramafic lamprophyres (UMLs) are mantle rocks that provide important information about the composition of specific carbonate–silicate alkaline melts in as well processes contributing to their origin. Minerals spinel group typically occur UMLs and have a unique “genetic memory.” Investigations minerals from Chadobets complex show physicochemical thermodynamic features rocks’ crystallization. The spinels these four stages first xenocrysts were found only damtjernite pipes, formed peridotite,...
Olivine from the deep mantle-derived rocks, such as ultramafic lamprophyres, carries important information about composition of mantle source, processes metasomatism, origin specific silicate-carbonate melts, well and mechanisms crystallization these rocks. Textures compositions olivine carbonate-rich lamprophyres (aillikites) Terina complex, along with their mineral melt inclusions, exposed that olivines have different sources. Two populations were considered: macrocrysts (>1 mm)...
The potential sources and conditions that control the formation evolution of alkaline melts are far from being fully understood. To address some these fundamental questions, we have focused on composition olivines spinel group minerals in aillikites Bushkanay dike Siberian Craton. These ultramafic carbonate-rich lamprophyres contain 40-50 vol% fresh olivine macrocrysts (200-600 µm) within a groundmass consisting phlogopite (60%), magnetite (15%), perovskite (10%), apatite (5%), calcite (3%),...
Dismembered ophiolites in the Early Paleozoic Olkhon terrane, a part of Baikal collisional belt southern periphery Siberian craton, occur as fault-bounded blocks ultramafic and mafic rocks from few meters to hundreds size. The are mainly dunite–harzburgite peridotites with gradual transitions between lithologies, well moderate amounts enstatitite, wehrlite, clinopyroxenite, but no lherzolite. Most have strongly depleted chemistry mineralogy corresponding harzburgite type usual for...
We announce the second edition of Aerospace geological map Olkhon Region (Baikal, Russia), scale 1:40 000, which was published in 2017. The has been considerably revised and updated, its changes are critical for correct understanding regional geology, tectonics geodynamics. Only a small number printed copies have released, therefore may not be available all interested specialists. electronic version is studying and/or printing (see link to pdf file paper's supplement). about 68 MB, i.e....
Aillikites are kimberlite-like rocks, important for understanding the composition and processes occurring in mantle. Melt inclusions represent a reliable source of information. The paper provides first results studies (Raman, EDS) on primary secondary melt olivine from Ilbokich uplift aillikites. is close to that parent It was significantly enriched CO 2 , H O, phosphorus titanium. Phlogopite, diopside, dolomite, calcite, apatite, Ti-containing phases (brookite, perovskite, Ti-magnetite)...
The paper provides details of local geology and mineralogy the Tazheran Massif, which was sampling site perovskite used as an external standard in U-Pb dating by sensitive high-resolution ion microprobe (SHRIMP) laser ablation inductively-coupled plasma (LA–ICP–MS) mass spectrometry. Massif is a complex igneous (mafic dikes, syenite, nepheline syenite), metamorphic (marble), metasomatic (skarn, calc–silicate veins) rocks. Metasomatites are thin restricted to interior being absent from...
Pyrochlore group minerals are the main raw phases in granitic rocks of Katugin complex-ore deposit that stores Nb, Ta, Y, REE, U, Th, Zr, and cryolite. There three types: Primary magmatic, early postmagmatic (secondary-I), late hydrothermal (secondary-II) pyrochlores. The primary magmatic phase is fluornatropyrochlore, which has high concentrations Na2O (to 10.5 wt.%), F 5.4 REE2O3 17.3 wt.%) but also low CaO (0.6–4.3 UO2 2.6 ThO2 1.8 PbO 1.4 wt.%). this type very rare nature limited to a...
Pyroxenite and nepheline-pyroxene rocks coexist with dolomite-bearing calcite marbles in Tazheran Massif the area of Lake Baikal, Siberia, Russia. Pyroxenites occur a continuous elongate zone between beerbachites (metamorphosed gabbro dolerites) 5 cm to 20 m fragments among marbles. Pyroxene pyroxenite is rich calcium alumina (5–12 wt% Al2O3) has fassaite composition. The may originate from mafic subvolcanic source indicated by presence remnant dolerite found one body. This origin can be...
