Come and make your first geological map at the Hallett Cove Conservation Park, South Australia! This site hosts some spectacular folds at Black Cliff that are the focus of our mapping exercise. We will learn about the major rock types and their structural features, how to use a geological compass to measure planes and lines, and the essential elements that make up a geological map.
0:00 Introduction
0:38 Rock Type 1: Siltstone (Brachina Formation)
2:34 Rock Type 2: Glacial Sediment (Cape Jervis Formation)
