Abstract (in english)
   The article deals with the geological setting of the area delimited by the line Stráž pod Ralskem-Hvězdov-Bezděz in the east and by the boundary of the military reserve in the west. The history of its knowledge from the early studies by Wurm, Zahálka and Müller up to the present is reviewed. The area is formed by Cretaceous rocks with the only unit exposed being the Jizera Formation sandstones. The basement of the cretaceous is represented by the proterozoic rocks (gneisses, mica-schists) in the Kumerské pohoří Hills, Lower paleozoic rocks (phyllites) N and NE of Mimoň, and by the Upper paleozoic rocks (sediments, paleovolcanites) between Mimoň and Hvězdov and in the Doksy area. Numerous volcanic and subvolcanis bodies (dykes and sills, intrusions, intrusive breccias) are of Upper Cretaceous to Tertiary age and mostly form morphological elevations. A characteristic feature of the Jizera Formation sandstones is the presence of small-scale and large-scale upwards coarsening cycles.
   Three large-scale cycles starting with fine-grained sandstones , often with calcareous intercalations, and ending with coarse-grained sandstones with conglomerate beds constitute the herein delinated lower, middle and upper part of the Jizera Formation. In addition, sharply bouded conglomerate of the presently used lithostratigraphic units with the classification of the former authors is shown
