Lithofacial Map of the Quaternary 1 : 50.000 - Digitized data Sheet 1968 Berlin/Nordost

The Lithofacial Map of the Quaternary 1 : 50,000 (LKQ 50) is a map series of the GDR covering nearly the whole former state territory besides the South of Saxony and Thuringia. The series consists of 123 map sheets, each of which encompassing several horizon maps mostly complemented by about five cross sections. Specifications concerning map content and structure provides Cepek (1999). The data of the LKQ 50 map sheet 1968 Berlin/Nordost provided here were digitised in frame of the Geo3D-Oder project of the German Federal Institute for Geosciences and Natural Resources (BGR). The data include elements of the seven horizon maps 1968-2, 1968-3, 1968-4, 1968-5, 1968-6, 1968-7, and 1968-8. Sheet 1968 Berlin/Nordost was published at an early stage of the map series preparation in 1972. Therefore, the topics of these maps are defined in a primary version 1 of the general legend. In contrast to map sheets of a later publication date the single horizon maps of 1968 Berlin/Nordost lack map legends to provide a specific stratigraphic and genetic classification of the depicted strata. However, as each horizon map comprises just two to four layers, this assignment can be derived from the signatures and the stratigrafic indication of the respective horizon map. For each horizon map the digitised elements comprise several polygon shapefiles of the single layers, a polyline shapefile of isohypses related to layer bases, a point shapefile of lithological profiles and a polygon shapefile of additional information concerning areas of heavy strata deformation and insufficient investigation. Non-numeric contents of the attribute tables are encoded by numbers and are translated in full text by means of key tables. The key table Normalprofil allows the stratigraphic and genetic classification of horizons displayed in horizon maps by code numbers of the column N_ID. Detailed descriptions concerning the data structure are provided in the attachments. Reference: Cepek, A. G.
