This text tries to overcome the lack of existing literature linking theoretical concepts and practical exercises in geological maps. This book starts from cutout plates, continues relating basic cartographic elements with topography and finishes interpretating more complicated geological maps, as a result of many years of selecting, preparing and experimenting with several map exercises. This book may be a useful resource at every level in which geological mapping is taught. By learning basic geological structures and their cartographic representation it should be possible to interpret advanced geological maps.
