Determination of major and trace elements in natural silicate minerals using LA-ICP-MS


Nina Grdenová


Major elements (Al, Si, K, Fe), as well as trace elements (Ga, Ge, In, Sn, Tl) were determined in
whole rock samples and in major rock-forming minerals, such as quartz, feldspars, micas and
amphiboles. The prime interest was observation of twins Al/Ga and Si/Ge, which should be the
indicator of different magmatic (e.g. source of the parental melt and the degree of its
fractionation) and hydrothermal processes (e.g. greisenization). The second one was determination
of differences in contents of these elements among individual mineral species - differences based
on crystal structure.
