Abstract
This paper presents a series of techniques that teachers can use in the classroom to familiarise their students with the fundamentals of geological mapping. By following the detailed practical explanations provided in this text, teachers can guide students to think about: i) topographical contour maps, ii) geological outcrop patterns and the V-rule, iii) true and apparent thickness of layers (strata/units). The sheets (2-D and 3-D geological paper models) provided herein offer a better understanding of the concept of geological maps. A practical case study is described that analyses the geological mapping of the city of Huelva, also presenting a 3-D geological model with sub-horizontal strata.
