This report summarizes the work and partial results made under the Public Procurement Obtaining Data from the deep horizons of the Rožná Mine in the first phase of the third and fourth subdivisions from February to November 2018. These are in particular technical works (boreholes, access to corridors),seismic measurements, sampling for laboratory analysis (physical-mechanical properties of rocks, breakage fills, bearing revalidation), structural characterization of the rockanalytical work on all samples taken. Parallel to these works3D models are being prepared, especially data preparation for modeling.

Realization project summarizes the planned work, its progress and continuity within the environment of Rožná I mine in the extent of the procurement „Získání dat z hlubokých horizontů dolu Rožná“ which is being compiled by Hluboké hluboké horizonty Rožná group. The final goal is to clarify the significance and spatial influence of major tectonic fault on surrounding rock mass. The results will help to clarify localization and safety issues of the potential deep underground repository, especially with respect to the Kraví hora locality.
Mafic and intermediate intrusions accompanying peraluminious granites of the Krušné hory Mts.batholit

Mafic and intermediate intrusions commonly accompany Variscan granitoid plutons in Europe. They are documented from different localities of Iberian Peninsula, from the French Massif Central, Schwarzwald, from different parts of the Bohemian Massif, in Romania, Greece, Corsica and Sardinia. They comprise wide petrographic varieties from quartz gabbros, diorites, granodiorites to monzonites. They usually constitute small bodies or veins, they often occur as mafic microgranular enclaves (MME) in granodiorites and in some granites. Dioritic intrusions are characterized by a relatively high amounts of lithophile elements (Rb, Sr, Ba, Cs, LREE), and they are simultaneously high in compatible elements (Ni, Cr, V a Co). Their isotopic ratios 87 Sr/86 Sr are in all compared locations similar and are close to the Bulk Earth (0.704 - 0.708). εNd values show larger scatter, some intrusions have more crustal composition (to -8), on the other hand, another intrusions have εNd positive, that points to a contribution of basic magma. The age of dioritic intrusions differs according to individual locality suggesting more than one magmatic episode. The oldest occur in the French Massif Central (361 - 365 Ma), whereas the youngest are documented in Iberia (312 - 310 Ma). The oldest mafic intrusions in the Bohemian...
