Description
| - Studie dokumentuje změny chemického složení křemene během vývoje dvou kontrastních pozdně variských granitových plutonů v Krušných horách. Obsahy Li, Be, B, Al, Ge, P, K, Na, Ca, Ti, Mn a Fe byly stanoveny in situ pomocí metody LA-ICP-MS. Al dosahuje ve všech vzorcích nejvyšších obsahů ze všech stanovených prvků (100-1200 ppm), následován Ti, Li, a K v řádu 10-100 ppm. Obsahy B, Be, Ge, Fe, Mn a P v křemeni se pohybují kolem 10 ppm. Diagram obsahů Ti vers. Al v křemeni je nejvýstižnějším indikátorem vývoje granitové taveniny z níž křemen krystaloval. (cs)
- The study documents changes in the chemical composition of igneous quartz during evolution of two contrasting late-Variscan granite suites in the Erzgebirge/Krušné Hory Mts., Czech Republic. Contents of Li, Be, B, Al, Ge, P, K, Na, Ca, Ti, Mn, and Fe were determined in situ using LA-ICP-MS. Al reached the highest contents in all samples (100-1200 ppm), followed by Ti, Li, and K (in the range of 10-100 ppm). The contents of B, Be, Ge, Fe, Mn, and P in quartz are usually lower than 10 ppm. The Ti versus Al diagram is the most fitting indicator of the evolution of the melt from which the quartz crystallised.
