MINERAL INCLUSIONS IN ZIRCON FROM THE VELYKA VYSKA SYENITE MASSIF, UKRAINIAN SHIELD

Language: Ukrainian

Mineralogical journal 2019, 41 (2): 34-44

Abstract:

Mineral inclusions in zircon crystals from syenites of the Velyka Vyska massif (Korsun-Novomyrhorod pluton) were investigated by electron microscopy and X-ray microprobe analysis. The aim of the research was to determine chemical composition of inclusions and conditions of their enclosing by zircon crystals. Fluorapatite, K-feldspar, albite, quartz, chalcopyrite, REE-carbonates, fluorbritholite-(Ce), monazite-(Ce), and Al-Fe-silicate phases are identified as inclusions in zircon. With the exception of proto- and epigenetic inclusions of apatite, all other mineral phases identified in zircon crystals are products of crystallization of a conserved magmatic melt. They are crystallized slightly later than the host mineral which explains how the lower-temperature minerals were captured by zircon. The diverse composition of the inclusions of preserved melts indicates the immiscibility between leucocratic (salic) and melanocratic (mafic) silicate melts as well as between silicate and salt melts. Immiscibility existed at both macro (in syenitic magma) and micro levels (in zircon crystals). The obtained data have confirmed the conclusions made by precursors about the heterogeneity of the environment of zircon crystallization from the syenites of pluton, supplemented and systematized them. The list of mineral phases from inclusions in zircon is partially different from those of Velyka Vyska syenites that makes mineral phases in crystals promising for the search of new mineral species.

Keywords: zircon, mineral inclusions, immiscibility of melts, Velyka Vyska massif.
