Tato práce je zaměřena na problematiku chemizmu staurolitu z oblasti silezika. Z vybraných lokalit byly odebrány vzorky staurolitických svorů, z nichž byly zhotoveny výbrusy, a ty vyhodnoceny pomocí polarizačního mikroskopu. K získání údajů chemizmu byly využity WDX analýzy, jejichž výsledky byly porovnány mezi sebou i mezi daty publikovanými v literatuře.The thesis is focused on the chemisty of staurolite from mica schists and similar staurolite- containing rocks in Silesicum. From selected locations samples of staurolite mica schists were removed, from which were made polished thin sections and they were studied by a polarizing microscope. WDX analysis were used to obtain chemistry data. Results were compared between each other and also with other studies from the literature.
