Structural Analysis of the Snake Range ‘Décollement,’ East-Central Nevada

摘要: Minor structures associated with the Snake Range “decollement” at six sites in east-central Nevada are used to infer direction of movement rocks above respect below. Analysis indicates latest varied each site and was down present dip “decollement.” The directions inferred range from westward through southward eastward. When combined evidence Tertiary age for on “decollement,” data support a denudation fault model rather than regional Mesozoic decollement models. This suggests that tectonic pattern may have more do post-Eocene evolution Great Basin ignimbrite-block province Sevier orogenic belt.
