Skalice quartzites and their relationship to overlain volcanic rocks
Abstract
The locality of Skalice, lying on slopes of Dlouhý vrch Hill N of Litoměřice, has been renowned for the finds of Eocene flora in quartzites. Tabular to lenticular quartzite bodies overlie the Merboltice Formation sandstones. They are overlain by volcanic rocks of the Děčín Formation. The contact between the volcanics and the quartzites has not been encountered in outcrops, but documented from a test pit. The interval between the quartzite and the volcanic rock was found to be formed by kaolinic sand and altered volcanic rock. The character of the boundary permitted to decipher the conditions of the formation of the Skalice quartzites as products of hydrothermal silicification.
