Alterace Bi-minerálů: příklady z beryl-columbitových pegmatitů silezika, Česká republika

Abstract

The diploma thesis deals with mineralogy, crystal chemistry and alteration mechanisms of Bi-mineralization on an example of beryl-columbite pegmatites in the vicinity of Maršíkov village in the southern part of the Silesian Domain. Although much attention has been dedicated to the paragenesis of Bi-mineralization in ore deposits in the past, the alteration processes leading to the formation of secondary Bi-mineralization in beryl-columbite pegmatites have not yet been fully explored. However, the presence of this mineralization was proven in the past at some localities of beryl-columbite pegmatites in the Maršíkov region.
