Also called echelon faults. A group of faults arranged in an echelon pattern. When one side of an area is subjected to compression and the other to tension, echelon cracks form, and when the cracks are misaligned, it becomes an echelon fault. Echelon arrangements are also seen in folded mountain ranges. (→Faults) Source: Encyclopaedia Britannica Concise Encyclopedia About Encyclopaedia Britannica Concise Encyclopedia Information |
