Popis | Rokytná conglomerates and breccias are grey to red, coarse- to very coarse-grained, clast-supported sediments (locally, the matrix-supported varieties may occur). They are poorly sorted with rounded to subangular pebbles, max. size of clast is about 50 cm (along the a axis). Conglomerates and breccias (Fig. 5-1) are facially monotonous, the material was derived from easterly situated geological units. Culmian rocks (greywackes, shales, conglomerates) dominate here (89–99 %), Devonian to Lower Carboniferous limestones (Špaček et al. 2002) are locally common (up to 6 %). Quartz, quartzite and magmatic rock clasts derived likely from the Brunovistulian units are variably distributed. They are exceptional at Mečkov, but could be relatively common (up 3 %) in other exposures of the Rokytná Conglomerate. |
