Preliminary EMPA and XRD investigation on detrital minerals from the Štramberk Limestone in the Czech Republic
In this paper, detrital minerals (light and heavy) from the Štramberk Limestone in the Czech Republic are described for the first time. The identified minerals are quartz, hematite, goethite, apatite, monazite, zircon, pyroxene, chlorite, kyanite(?) and zircon. Most are minerals from igneous rocks. CHIME age determinations on a monazite grain give Variscan ages. The main calculated age is 334±5 Ma. In addition, three further ages, i.e., 392 Ma, 359 Ma and 309 Ma are indicated. The rounded shapes of some mineral grains, and the sharp, cracked and/or automorphic character of others, provide rather ambiguous information on their transport history and source area(s). However, the mineral inventory and the determined age may point to the Bohemian Massif as the source.
