Cominco American Well: Implications for the Reconstruction of the Sevier Orogen and Basin and Range Extension in West-central Utah
Re-evaluation of acoustic, gamma ray and dip meter logs from the Cominco American Federal No. 2 well in the Sevier Desert basin of west-central Utah sheds new light on the interpretation of Neoproterozoic and Cambrian stratigraphy and Mesozoic structure in a region that has been influential in the development of ideas about crustal shortening and extension. The most prominent of several major t...
متن کاملIs the Sevier Desert reflection of west-central Utah a normal fault?
A prominent west-dipping reflection that can be traced in seismic-reflection profiles over an area of 7000 km beneath the Sevier Desert basin of west-central Utah is generally referred to as the Sevier Desert detacbment and is widely regarded as one of tbe best examples of an upper-crustal low-angle normal fault. The absence of evidence for fault-related deformation in drill cuttings and core f...
متن کاملExtensional collapse along the Sevier Desert reflection , northern Sevier Desert basin , western United
Coogan and DeCelles (1996) provided a welcome addition to the debate on the Sevier Desert reflection. The evidence and arguments presented on the nature of this subsurface feature merit particular scrutiny, as they bear directly on a firstorder issue in tectonics: the mechanical paradox of low-angle normal faults. Field geologists have argued that in some cases such faults must have moved at di...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Late Quaternary faulting in the Sevier Desert driven by magmatism
Seismic hazard in continental rifts varies as a function of strain accommodation by tectonic or magmatic processes. The nature of faulting in the Sevier Desert, located in eastern Basin and Range of central Utah, and how this faulting relates to the Sevier Desert Detachment low-angle normal fault, have been debated for nearly four decades. Here, we show that the geodetic signal of extension acr...
