Abstract
The aim of my work, is to explore the general geology of the "Kleine Randen", which is a part of the "Klettgau". The "Klettgau" is located in Southwest-Germany. It is composed of the following components: "Wutachtal" (the valley of the river Wutach), "Rechberg-Hallauer-Rücken" (a ridge, mainly consists of Triassic sediments), "Klettgau-Rinne" (an ancient Valley of the Rhine, very important for the future water supply for the whole region), "Kleiner Randen" (a ridge, mainly consists of Jurassic and Tertiary sediments).
The essential part of my work are the jurassic sediments, especially the Upper Jurassic (Oxfordian) limestones, marl and marlaceous lime, which were deposited in an epicontinental sea north of the Tethys. These beds (primarily micrite, poor in fossils) dip gently to SE.
The Tertiary system is represented by the typical occurrence of bean ore in the base, and sediments of the molasse stratigraphically above. The Klettgau was located at the northern end of the molasse basin (parts of these sediments are thinning out).
Pleistocene gravel deposits are the youngest sediments.
