There is no obvious age difference between these various groups, so all of the magma-types were formed at the same time in a relatively restricted area and must therefore be petrogenetically related. Both sodic and potassic varieties of primitive silicate magmas are present. On major element variation diagrams, the cumulate rocks plot as simple mixtures of their constituent minerals (olivine, clinopyroxene, calcite etc). There are complete compositional trends between carbonatites, phoscorites and silicate cumulates, which suggests that many carbonatites and phoscorites are also cumulates. CaO/Al2O3 ratios for ultramafic and mafic silicate rocks in dykes and pipes range up to 5, indicating a very small degree of melting of a carbonated mantle at depth.

  • The Origin of Hydrocarbon Gases in the Lovozero Nepheline-Syenite Massif (Kola Peninsula, NW Russia), As Revealed from He and Ar Isotope Evidence
    minerals Article The Origin of Hydrocarbon Gases in the Lovozero Nepheline-Syenite Massif (Kola Peninsula, NW Russia), as Revealed from He and Ar Isotope Evidence Valentin Nivin Geological Institute, Kola Science Centre, Russian Academy of Sciences, 14 Fersman St., 184209 Apatity, Russia; [email protected]; Tel.: +7-815-55-79-580 Received: 15 August 2020; Accepted: 16 September 2020; Published: 21 September 2020 Abstract: The occurrence of hydrocarbon gases (HCG) in unusually high concentrations for magmatic complexes, in the Lovozero and some other alkaline massifs, is of both geochemical and practical interest. The nature of these gases, despite the long history of research, remains the subject of debate. As an approach to solving this problem, we studied the coupled distribution of occluded HCG and the recognized tracers of various geological processes, such as helium and argon isotopes. The extraction of the gas components trapped in fluid micro-inclusions was carried out by the mechanical crushing 3 4 of rock and mineral samples. A positive correlation was found between the He/ He and CH4/C2H6 ratios, whereas a negative correlation of the latter was found with the 36Ar concentration, which in turn was directly related, in varying degrees, to the content of HCG and most strongly with pentanes. Conjugacy of the processes of the heavier gaseous hydrocarbons, a loss of the deep component of the fluid phase and dilution of it with the atmogenic component was established. In the absence of a 3 3 correlation between CH4 and He, the value of the CH4/ He ratio in the Lovozero gas substantially exceeded the estimates of it in gases of a mantle origin, and mainly corresponded to the crustal values.

These compositions define a loparite evolutionary trend, represented by increases in Na and LREE, that is commonly accompanied by an increase in Nb and Th contents. The crystallization of secondary cerian perovskite and loparite results from either deuteric or metasomatic processes, and involves the interaction of prirnary perovskite vrith fluids derived from a cognate alkaline or carbonatitic source.
