Description
  • Skalické/Žitenické kvarcity u Litoměřic vznikly kvarcitizací paleogenních písků odvozených od svrchnokřídového merboltického souvrství. Objevení jejich prostorové souvislosti s basaltickými ignimbrity iniciovalo mineralogická a geochemická studia. Existence dvou typů prokřemenění vyplývá z odlišných kvarcitových subtypů: 1) zóna nasycení spodní vodou s permanentně cirkulujícími roztoky, 2) vyšší zóna bez permanentní přítomnosti spodní vody vystavená vyšším teplotám. Výsledky mikrosondového studia potvrzují u druhého typu genetickou spojitost s nadložním ignimbritem. (cs)
  • Quartzites of the Skalice/Žitenice type near Litoměřice, Ohře Rift graben, were produced by quartz cementation of Paleogene sands derived from the Upper Cretaceous Merboltice Formation sandstones. Their mineralogical and geochemical studies were motivated by the find of their spatial relationship to a flow of basic ignimbrite. Two types of quartz cementation were documented implying different silicification settings: 1. the zone of permanent groundwater saturation, and 2. the overlying unsaturated zone exposed to higher temperatures, with crystallographically confined quartz overgrowths. Results of microprobe studies of the latter type of cement and the overlying ignimbrite revealed parallels (elevated Al2O3 contents) confirming their genetic relationship.
