I have a homework question that I'm stuck on, I have attempted interpreting this map but am not sure if I have to correct interpretation.
- What is the youngest/oldest rock in the geological history of this map?
By law of superposition, oldest: limestone, youngest: mudstone. For this question, I'm used to looking at the law of superposition to determine age but in this diagram the contours don't tell me anything. Did I get these right?
- What type of fold is shown on the map?
- Give a brief geological history of map.
This is the one I need most help in. Magma intrusion at fault lines? Maybe some mudstone intrusion over limestone?.
Again, please tell me if these answers are wrong.
