Geological mapping of the Lusatian Massif in the Šluknov area on a scale of 1:25 000
Abstract
Geological mapping in the scale 1:25 000 of the Šluknov area has been proceeding since 1998 and was finished in the year 2002. The mapping and geochemical study of Lusatian granitoid complex show that boundaries of various granitoids are mostly tectonic. Petrographical and geochemical data indicate a gradual sequence from Lusatian granodiorite (the Herrnhut type) over the Václavice granodiorite (to granite) and the Brtníky granite to the Rumburk granite. The Neoproterozoic to very early Cambrian Lusatian granodiorites may be interpreted as pre-plate collision and post-collision uplift granitoids. Other cambrian to Ordovician granitoids are rather syn-collisional up to post-orogenic.
