Foreword

Shortly after publication of the German "Guidelines for the Compilation of Geological Maps", it became clear that there was a need for an English translation, as shown by an official inquiry from the British Geological Survey (BGS). The authors were, therefore, requested by the Federal-State Committee for GeoResearch, the Directors of the individual State Geological Surveys of Germany, and the Federal Institute for Geosciences and Natural Resources to prepare an English version. This English version provides a further basis for close, cross-border co-operation on geological mapping. The International distribution of these mapping guidelines, tested in practical application and containing recommendations and examples, is meant to support efforts to set up practical international standards. The mapping guidelines presented here are only those used by the State Geological Surveys of Germany. It is possible, however, for the core concept to be applied by other Geological Surveys. The authors wish to express their appreciation to STEPHEN J. BOOTH and his colleagues at the British Geological Survey in Keyworth for critical review of the manuscript and support for the translation into English.

Abstract

Geological mapping provides basic information on the geological structures and stratigraphy of an area. Maps are the usual form of representing geological data. Guidelines for data acquisition and evaluation, as well as for the preparation of the geological map (analog and digital), the legend, and the Explanatory Notes, have been prepared so that the geological maps will be uniform. These guidelines should help beginning geologists in the Geological Surveys, students, and geologists who are not employed by a Geological Survey to carry out their work in an efficient and targeted manner.
