| Popis | Thirteen mafic microgranular enclave-host rock (ME-HR) pairs were examined microscopically and geochemically. Mutual relation between modal composition of both members is apparent, particularly in mafic minerals contents. All ME display SiO2 depletion and are enriched by MgO, Fe2O3t, CaO, Cr2O3, NiO and Co, indicating basic and more primitive source of ME melt compared to their respective HR. Also, the REE contents are elevated in all ME. It seems that the presence of plagioclase xenocrysts in ME, apparently cognate spidergram patterns and obvious elements correlations indicate mutual mechanical and chemical magma interactions. |
