Minerals published during the period 2006 to 2010 from the area of Slovak Republic are described in this paper. The descriptions of 237 mineral species including 5 elements, 65 sulphides and sulphosalts, 3 halides, 36 oxides and hydroxides, 18 carbonates, 14 sulphates, 34 phosphates including…

Tourmalinites (Tu+Qtz+Ms+Chl±Grt) from the Krkonoše-Jizera Crystalline Massif form stratiform layers hosted in mica schists (Ms+Qtz+Grt+Chl±Tu±Bt). The tourmaline usually exhibits three compositional domains. The oldest Mgrich tourmaline (Mg/(Mg+Fe) = 0.81 - 0.99) with fine-grade zoning…

Supergene native silver and acanthite were identified at the Jasenie-Soviansko base metals deposit, Nízke Tatry Mts., Slovak Republic. Both minerals occur in cavities of quartz-sulfide vein material together with cerussite, weathered tetrahedrite, barite and quartz crystals. Native silver forms…

The peraluminous granites form small (1 - 2 m thick) dykes located in the Sedlec granodiorites near the contact with durbachites of type „Čertovo břemeno“ on the eastern margin of the Central Bohemian Plutonic Complex. Two distinct textural types have been distinguished: nodular tourmaline granite…

Kerimasite Ca3Zr2(Fe3+2Si)O12, a rare member of garnet supergroup, was identified by EMPA in Ca-Mg skarn on the contact between Miocene granodiorite porphyry intrusion and Middle Triassic dolomites in a borehole from the Cu-Au skarn-porphyry deposit Vysoká-Zlatno near Banská Štiavnica (Štiavnické…

Vein-type deposit of silver and copper Vejprty was mined from half of the 16th century till half of the 19th century. Steep veins of various directions and thickness from 10 to 80 cm penetrate mainly through metapelites (paragneisses) originated from Proterozoic pelites during the Variscan…

Linarite, supergene Pb-Cu sulphate, was found at small mine dump Grubenwall „42” near Dolní Kramolín (historical ore district Michalovy Hory, Czech Republic). Linarite forms dark blue coatings and rarely deep azure blue short columnar crystals up to 1 mm in size with glassy luster. The unit cell…

After about 180 years of doubts, presence of Cenozoic alkaline volcanic neck has been affirmed in Luže as far as 150 km off the Eger Rift. The Chlumek basanite is located some 800 m northwest from well-known Košumberk basanite and its top hosts church of Virgin Mary. The rock is composed of olivine…

Two exceptional old samples of goethite from the locality Šonov near Broumov (Czech Republic) were newly registered into the mineralogical collection of the National Museum in Prague. They form brown radial aggregates with the length of fibers up to 10 cm. Both samples were found in the 19th century…

The hexahydrite and ranciéite have been found in travertine or calcareous tufa, respectively in the Vyšné Ružbachy locality. They were identified by the X-ray diffraction methods. Hexahydrite occurs in the thin layers of white colour covering the weathering rocks. Chemical weathering of carbonate…

Gold was one of ores of lower importance in the Březové Hory ore deposit, Příbram, Czech Republic. Although gold was relatively common in the Příbram area, specimens with macroscopic gold grains from the Březové Hory deposit were very rare. The studied sample was collected on dump of the Ševčin Mine…

Supergene mineralization with corkite and bariopharmacosiderite-Q, formed by alteration of primary arsenopyrite and galena, was found at the Vysoká hill situated 5 km in the south-east direction from Havlíčkův Brod, Czech Republic. The corkite, PbFe3(SO4)(PO4)(OH)6, formed small (below 2 mm)…

An interesting association of supergene uranium minerals represented by natrozippeite, zinczippeite, andersonite and zellerite was found at the 12th level of Banská Štiavnica base metal deposit. The most abundant supergene phase, natrozippeite forms bright yellow crystalline coatings which consist…
