Geology of the Søby-Fasterholt area. Text

Abstract

A general description of the Quaternary and Neogene of Central Jutland follows after an introductory survey of previous investigations in the area and the general regional geology of the Neogene of Denmark. The Quaternary morphology and especially the solifluction deposits and periglacial structures are described. The Tertiary deltaic browncoal bearing deposits of the S0by-Fasterholt area are described in detail (lithostratigraphy) based upon exposures, wells and the petrography of the browncoal seams. The Miocene marine Hodde Formation and the outcrops of the Gram Formation of the Søby-Fasterholt area are described in general. The Fasterholt Flora especially, but also the Damgaard Flora and the Søby Flora, is discussed in an extended chapter on the biostratigraphy, and the pollen- stratigraphy is compared to the Lower Rhenian region. Finally, The exposures revealing pre-Weichselian disharmonic folding and faulting caused by compression are described and compiled.
