First announcement of international workshop<\/p>\n

Vertical zoning of tin granite plutons in light of modern analytical methods<\/p>\n

A 1596 m long fully-cored borehole CS-1 was realized in 1961-1963 in the C\u00ednovec\/Zinnwald granite cupola, Kru\u0161n\u00e9 Hory\/Erzgebirge, Czech Republic. For more than 50 years this borehole represents one of the most inspiring sources of our knowledge about evolution of rare-metal granite plutons through the world.<\/p>\n

Vertical zoning of the C\u00ednovec cupola involving albite-lepidolite, albite-zinnwaldite, and albite-biotite granites combined with microgranites, feldspathites, greisens, and flat quartz veins gives an excellent opportunity for the study of magmatic\/hydrothermal evolution of Sn- W-Nb-Ta-Li-bearing system and formulation of genetic models.<\/p>\n

Rapid development of microanalytical methods in two last decades, electron microprobe and laser-ablation ICP-MS analyses, provides new, high precision chemical and mineralogical data. Back-scattered electron and cathodoluminescence imaging enable objective study of rock- and mineral textures. New data support formulation of more presumable genetic models.<\/p>\n

Mining of tin and later also tungsten ores operating in C\u00ednovec from the 16. century was interrupted in 1991. At present, some attempts for re-opening of the mine are going on. So the theoretical models may be immediately used in praxis.<\/p>\n

Within the frame of Czech Science Foundation project No. P210\/14\/13600S we acquire principally new data about whole-rock and mineral changes along the borehole CS-1. In order to present these data, provoke discussion about the most plausible evolutionary model of this granite and deposit, and compare this object with other rare-metal granites worldwide, we organize two-day workshop connected with excursion to old tin mines in Krupka (Bohemia) and Zinnwald (Saxony).<\/p>\n
