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

9814356怀尔德最近北美西缘的研究表明，早白垩世沿着内华达山脉中部发生了大规模的右旋走滑断层，而这个断层系统被假定沿着边缘延伸得更远。然而，目前的年龄限制和北方的几何关系不允许对此进行测试。之前在内华达州西北部/俄勒冈州南部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-雪湖断层向北延续的候选者。它似乎与北部庞大但有问题的爱达荷州缝合线特征保持一致。这项研究是莱斯大学和佐治亚大学研究人员的合作成果，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探索这种潜在的相关性。这一结果将对北美西部边缘中生代历史的构造重建至关重要。

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.
