The paper provides a review of calculations and experimental approaches to reproducing three types of crystal size distributions (log-linear, bimodal, lognormal CSD) and systematizes publications on CSD data in rocks of ten known layered massifs. For a more detailed discussion, the results for plagiodunite samples from the Yoko-Dovyren massif, northern Baikal region, Russia, harzburgite from the marginal zone of the Monchegorsk pluton, and urtites from the Lovozero intrusion, Murmansk region, Russia, were selected. Possible causes and scenarios for the formation of three types of CSD established for these intrusive objects are presented.

Based on published geophysical and petrological data, lower crustal fluid reservoirs have been proposed below the Klyuchevskoy Volcano, expressed as a low Vp/Vs anomaly. A high Vp/Vs anomaly under the proposed fluid reservoir is interpreted as a zone of magma accumulation. The localization of fluids in these reservoirs in the ductile lower crust can vary from isolated inclusions to filling of microfractures over a time scale of several months. Using a simplified poroelastic model, it is shown that the transition in the topology of pore space filled with fluid or melt can provide the observed changes in Vp/Vs in the anomalies of high and low values at a melt content of several vol % and fluid content less than 1 vol %, respectively. In zones of active volcanism, such as the Klyuchevskaya group of volcanoes (KGV), fluid reservoirs are localized in ultramafic cumulates formed during the early high-temperature stage of magma fractionation. Ultramafic xenoliths in the products of eruptions of the KGV and Avachinsky volcanoes, often interpreted as mantle rocks, formed at pressures of about 5 kbar or depths of about 18–20 km in accordance with two-pyroxene geo-thermobarometry and the content of volatiles in melt inclusions in olivine and spinel. When crossing by ascending magmas, the fluid-containing reservoir experiences mechanical failure and injects a certain amount of fluid into the magma, which then captures pieces of crushed magmatic cumulates. The composition of melt inclusions in olivine can reveal records of the magma-fluid interaction.

The effects of the content of alkalis on zircon solubility in multicomponent model silicate melts was experimentally studied within the temperature range of 1300–1400°C and 1 atm total pressure. It was demonstrated that the addition of Na2O and K2O to the melt results in a comparable increase in zircon solubility. The advantages and disadvantages of the parameters describing the effects of the melt composition on zircon solubility are briefly discussed.

Numerous Neoproterozoic granitic intrusions occur over a north-south distance of more than 700 km in the western Yangtze Block. In this paper, we use zircon U-Pb age, Lu-Hf isotopic, and whole-rock geochemical data to show that the Shimian granitic pluton, which was previously thought to be S-type granite in the area, is actually A-type granite. The selected fresh samples for this study are mainly porphyritic biotite monzogranites. They are weak peraluminous, A2-subtype granites, displaying high contents of SiO2 and K2O, low CaO, and Na2O, with the characteristics of high silica, rich potassium, and low sodium. They are enriched in incompatible trace elements, but low in trace elements compatible in mafic silicates and feldspars, and they are chemically characterized by having high REE and Ga abundances and low Al, Ni, Ba, Sr, and Eu abundances. The major and trace element behavior suggests that the granites underwent the process of advanced fractional crystallization and were likely generated by crustal partial melting. Zircon U-Pb age shows the Shimian granitic pluton was emplaced at 728 ± 20 Ma. The studied granites yield an average 176Hf/177Hf value of 0.282363 (εHf = 0.8) with a 94% confidence interval of 0.282334 to 0.282384 (εHf = −0.1 to 1.7), indicating that they are derived from the remelting of juvenile continental crust. We suggest that this newly identified A-type granite at Shimian, southwestern China, was more plausibly generated in an extensional setting as a result of slab window caused by ridge subduction, which can account not only for the formation of voluminous granitoids, but also for the basalts, boninitic pillow lavas, and SSZ-type ophiolites in western Yangtze Block.

The Rudnaya dyke of the Imangda ore cluster is composed of weakly differentiated olivine-bearing to olivine gabbrodolerites with globular and interstitial sulfides of a chalcopyrite–cubanite- (pentlandite-pyrrhotite) composition. Along with sulfide mineralization, gabbrodolerites of the dyke contain xenoliths of hornfelsed basalts, abundant amygdales and rare grains of zoned olivine-1 Fo90–47 that coexists with subhedral olivine Fo74–36 of the second generation. Modeling with the COMAGMAT and alphaMELTS programs showed that high-Mg Ol-1 with Cr-spinel inclusions cannot be crystallized from a Fe-enriched tholeiitic melt with 4.8–7.3 wt % MgO and 11.6–16.7 wt % total Fe2O3 that is parental for the dyke. The variation trend and high Ni up to 0.5 wt % NiO in the cores of xenocrystic olivine Fo90–76 in contrast to maximum Fo83 and 0.4 wt % NiO in olivine from the ore-bearing intrusions and picritic basalts of the Norilsk region point toward the presence of deep-seated cumulates of picritic magmas, which had not exchanged with sulfide liquid. Platinum group element (PGE) abundances increase (up to 2.2 ppm) with increasing Cu/Ni in the whole rocks and proportions of pentlandite in a sulfide association. A specific pattern of chalcophile metal distribution with Ni, Os and Ir minima, elevated Cu/Ni (5–15) and Cu/Pd (3200–10 900) along with lower PGE tenor (PGE content in 100% sulfide) of sulfides (2–65 ppm) and Pd content in pentlandite (<175 ppm) compared to those of the ore-bearing intrusions suggest that cuprous sulfide mineralization was not physically captured from highly fractionated sulfide fractions of ore-bearing magmas but is cogenetic with a magma of the dyke. Sulfide saturation, near-simultaneous with fluid saturation and degassing, was achieved in the dyke conduit due to assimilation of sedimentary sulfur and volatiles from Devonian evaporites that is supported by the heavy S isotope composition of dyke’s sulfides with the average δ34S = 14.7 ±1.1‰ (n = 31) close to the values for sulfides from the endocontact zones of the Imangda ore-bearing intrusions hosted by the Devonian sequences. The initial isotopic characteristics of dyke rocks (Sri 0.70517–0.70532, ɛNd from –0.4 to 0.8) imply its comagmatic origin with the Norilsk-type intrusions whereas the overall data do not exclude its spatial connection with an upper crustal conduit network of the ore-bearing magmas.
