COLLABORATIVE RESEARCH: Cretaceous-Age Crustal Discontinuity in the Black Rock Desert Region of Northwest Nevada: Kinematic Link Between the Mojave-Snow Lake Fault...

9814356 Wyld 沿着北美西缘的最新研究表明，早白垩世沿着内华达州中部存在大规模的右旋走滑断层作用，并且假定该断层系统沿边缘延伸得更远沿着。 然而，目前的年龄限制和几何关系的北部不允许这一点进行测试。 先前在内华达州西北部/俄勒冈州南部的黑岩沙漠地区的工作已经发现了大位移断层的证据，这可能是莫哈韦-雪湖断层向北延伸的候选者。 它似乎与北部大但有问题的爱达荷州缝合带特征对齐。 这项研究是莱斯大学和格鲁吉亚大学的研究之间的合作努力，并将通过对黑岩沙漠早白垩世变形的分布、运动学和时间演化的综合研究来追求这种潜在的相关性。 其结果将是至关重要的构造重建的中生代历史的北美西缘。

9814356 Wyld Recent research along the western margin of North America has demonstrated large-scale dextral strike-slip faulting in the early Cretaceous along the central Sierra Nevada, and this fault system has been postulated to extend much further along the margin. However, present age constraints and geometric relationships to the north do not allow this to be tested. Prior work in the Black Rock Desert region of Northwest Nevada/southern Oregon has discovered evidence for large-displacement faulting that is a likely candidate for the northward continuation of the Mojave-Snow Lake fault. It appears to be aligned with the large but problematic Idaho Suture feature to the north. This research is a collaborative effort between research at Rice University and the University of Georgia, and will pursue this potential correlation by an integrated study of the distribution, kinematics and temporal evolution of early Cretaceous deformation in the Black Rock Desert. Results will be critical to tectonic reconstructions of the Mesozoic history of the western margin of North America.
