COLLABORATIVE RESEARCH: Magnitude, Timing, and Paleogeogra-phic Significance of Mesozoic Compression and Cenozoic Extension in Centarl Mojave Desert, California

莫哈韦沙漠在美国西南部中生代和第三纪地质演化模式中占有重要地位。由于莫哈韦地块中新生代变形的性质鲜为人知，这些模型一直很难检验。这项工作将与北卡罗来纳大学和堪萨斯大学的工作人员合作，研究莫哈韦三个地点-克罗内斯山、阿尔沃德山和沃特曼山-变形的程度、运动学和时间。研究结果将有助于为该区中生代挤压和新生代伸展提供约束条件。

The Mojave Desert occupies an important position in models for the geologic evolution of the southwestern United States during the Mesozoic and Tertiary. These models have been difficult to test because the nature of Mesozoic and Cenozoic deformation of the Mojave block is poorly known. This work, in collaboration with workers at the University of North Carolina and the University of Kansas, will address the extent, kinematics and timing of deformation at three localities in the Mojave - the Cronese Hills, Alvord Mountain and Waterman Hills. Results will help provide constraints on Mesozoic compression and Cenozoic extension in this region.
