Not only mineralogy has a long tradition in the Carpa-thian region but mineral species, first described from here, also have their own, sometimes a long and eventful, history. A classic example is nagyágite: first found in 1747, described at the end of the 1760s, obtained its present name in 1845 but had the first reliable structural model only in...

Project
Project deals with identification of riftogenic zones in the area of the Western Carpathians and the neighbouring areas. It includes a longer time period from Late Proterozoic (at ca. 550 Ma) up to Mesozoic-Cenozoic boundary (at ca. 60 Ma), when riftogenesis continued with the opening of the main Tethyan oceans on the Earth. These preliminarily determined riftogenic zones will be investigated from the viewpoint of a long-term periodicity, intensity of magmatism, metamorphism and chemical elements mobility (recycling) between the crustal and mantle rocks: Late Proterozoic – Cambrian, Devonian, Permian – Triassic and Jurassic – Cretaceous. Specific groups of rocks and their minerals will be searched as indicators of the riftogenic zones, despite they often have signatures of superimposed tectono-thermal overprinting from their incorporation into the orogenic zones. Mineralogicalpetrological (EPMA, micro-Raman, LA-ICP-MS, XRF, ICP-MS), isotopic-geochemical (LA-MC-ICP-MS, TIMS) and geochronological (U-Pb SIMS, LA-ICP-MS, Ar-Ar, K-Ar) methods will be applied to establish the chemical composition of minerals and rocks, their isotopic characteristics (U-Pb, Pb-Pb, Sm-Nd, Rb-Sr, Zr-Hf, Re-Os) and the ages. Geothermobarometry and thermodynamic modeling with Melts, Perple_X and Thermocalc software will be used for estimation of P-T conditions of the crustal and mantle rocks mineral parageneses formation. This database can reveal the rocks origin and their magmatic and metamorphic evolution stages. We will suggest interpretation models addressed to paleotectonic zones of riftogenesis defined with typical rock associations and their mineralogical-petrological, geochemical and geochronological characteristics. Classification of riftogenic zones and their relationship to the opening of the Tethyan oceans will be confronted with published hypothetical models of riftogenesis as the domains of crust-mantle interaction and recycling, often with a significant economic potential.

This project will inspect remobilisation/fractionation of lithophile elements under low-T/supegene conditions where some important geochemical-biochemical processes may have occurred. Describing it in detail is an essential step towards an understanding of the behaviour of such elements in near-surface conditions.
