Deformation pattern around the conjoining strike-slip fault systems in the Basin and Range, southeast Nevada: the role of strike-slip faulting in basin formation and inversion

Article Abstract:

A study was conducted on deformational features around the strike-slip fault systems in the Basin and Range Province, southeast Nevada. Results showed that the basin north of Las Vegas, NV, its intense contractional deformation and the southward shift of deposition during inversion may have been produced by the Las Vegas Valley shear zone and the Bitter Spring Valley fault. These results suggest that basin formation and localized vertical tectonics can arise from strike-slip fault systems.

Mechanisms of inheritance of rift faulting in the western branch of the East African Rift, Tanzania

Article Abstract:

The Proterozoic deformational stages and associated deformational characteristics of the Precambrian basement of the western Tanzanian rift zone are investigated. Structural data indicate that strike-slip regimes comprise the leading deformational mechanism in Proterozoic events that affect the basement. Data also show that strike-slip faulting is rarely recognized in ancient orogenic belts than in existing plate boundary orogenic settings.

Strike-slip faulting and block rotation along the contact fault system, eastern Prince William Sound, Alaska

Article Abstract:

Structures and kinematics ineastern Prince William Sound near Valdez show deformation associated with dextral strike-slip post-dating the initial accretion. Moreover, the faults in eastern Prince William Sound compose a dextral transform system that representsa major crustal discontinuity. Lastly, the convergence in eastern Prince William Sound changed from nearly orthogonal to highly oblique during Eocene.
