Field geologists measure the strike and dip of exposed rock layers to infer the form of a geologic structure such as a fold or basin. Measurement of strike and dip, also known as the attitude of rock layers, helps geologists construct accurate geologic maps. For example, data on rock attitudes helps delineate fold structures in layered rocks. The attitude of other geologic structures like faults can be understood using strike and dip as well. Despite the central role of strike and dip in structural geology, Geoscience students often have particular difficulties understanding these concepts. Here, we designed an online learning tool that provides students with the unique opportunity to creatively explore the concepts of strike and dip.
The SaD (Strike and Dip) tool:
The SaD (Strike and Dip) tool is an experience created for the purpose of helping students learn about taking the strike and dip measurements from 3D models of geological structures. With this tool, students can learn what strike and dip measurements are as well as practice taking those measurements using a variety of geological structure types from all around the world.
