stenos principle

Layers 1, 4, 5, and 6, intrusions 2 and 3, fault B

Layer 4 is the oldest because it it at the bottom. Then 5 because it is the layer above that. Then intrusion 2 because it cuts into 4 and 5 but not 6 and1. Then fault b because it cut into intrusion 2 and layers 4 and 5. Then layer 6 because it is lower then layer 1 and intrusion 2 is lower then it and it does not get cut by fault b. Then layer 1 because it is higher then layer 6. Then intrusion 3 because it cuts into everything.
