![]() This is the view of geological structures you also see when you drive through the mountains and the roads have been cut through the rocks, exposing structures in the rock that you wouldn’t see otherwise. If you look at a block from along the side, you are seeing the cross-section view. ![]() Block models and block diagrams assist in visualizing how 3-D geological structures in the real world can be represented in two dimensions on a map or in a geological cross-section.Īs you examine the block diagrams in the figures in this section, note the different ways that you can view them: from above, or from the sides. Block diagrams are images based on three-dimensional (3-D) block models, which are blocks of wood or paper with geological structures marked on them. To learn many of the concepts associated with structural geology, it is useful to look at block diagrams and block models. In Part I of geological structures, students will learn how to interpret strike and dip information from a geological map, prepare a geological cross-section from a plan-view geological map, and measure the thicknesses of geological units.
