In this question you will be drawing a section of a cliff that comprises three rock types A,B,C. A geologist sees a cliff where rock C forms the lower half of a cliff, and is immediately overlain by a sandstone (rock B) comprising well rounded grains with finely pitted surfaces. the sandstone reaches to the top of the cliff. In this cliff exposure a gabbro (rock A)dyke passes right through both other rock types. draw a section of the cliff and show the relationship between rocks (A,B,C) label and provide a key.© BrainMass Inc. brainmass.com December 15, 2020, 2:08 pm ad1c9bdddf
Based on the scenario, this solution provides a diagram of cliff showing the relationship between rocks (A,B,C), labels and provides a key. It also uses the principles of relative dating to describe this relationship.
