Quaternary geological overview map of Lower Saxony 1 : 500 000 - Depth of Quaternary Base
Description
The map of the depth of the quaternary base in Lower Saxony 1 : 500 000 provides a nationwide overview of the location of the base of quaternary deposits and formations in Lower Saxony. The specification of the depth is based on evaluations of drilling and geophysical measurements, the representation is in the form of isolines in meters relative to NN. This map provides an overview of the large-scale construction of the underground. Point-by-point or small-scale statements are not possible with this overview map, since details of the heavily reliefed quaternary base area on a scale of 1: 500 000 cannot be represented.
The Quaternary period is divided into the Ice Age (Pleistocene) and the post-glacial period (Holocene). Overall, the Quaternary in Lower Saxony is characterized by a multiple change of cold and warm periods, each of which has left characteristic deposits and formations. The quaternary base is formed by rocks of the tertiary or older solid rocks.
The nationwide reference of the depth of the quaternary base to NN makes it possible to draw conclusions about the overall thickness of the quaternary deposits and formations when additional reference is made to an elevation model of Lower Saxony.
