Kinematics of rock deformation

地球系统的动态演化主要受内部能量的产生和损失控制，表现为板块构造和岩浆作用，以及外部能量的获得，如陨石撞击过程。对这些过程的理解，在不同的长度和时间尺度上，是我研究的基础。具体地说，我建议从事以下工作：(1)分析断层系统及其对安第斯山脉中部(阿根廷西北部)火山中心活动的影响；(2)造山带的地壳变形，特别是东佩诺基山造山带(安大略省)；(3)复杂撞击坑的形成(霍顿、德文岛和安大略省萨德伯里)。由于这些研究领域对地质灾害评估和自然资源储量定位具有重要意义，因此具有很强的社会经济意义。所有项目的关键将是可视化变形岩石体积的三维(3D)结构，恢复其变形前的形状，并分析变形机制。这一方法有望更好地理解岩石从毫米尺度到地壳尺度的动态变形，以及在不同时间尺度上的动态变形，更具体地说，火山杂岩的喷发触发、内生熔体的迁移和侵位、应力积累、矿床成因和撞击坑的形成。从长远来看，我打算通过将从自然实验室的面向过程的研究中收集的构造地质地面事实与变形的定量运动学恢复和(模拟)模型研究联系起来，缩小地质场和数值模拟研究之间的差距。这种方法还有助于生成更逼真的岩石变形模型。我与工业界合作进行的关于矿床形成和本地化的研究，将有助于设计以过程为导向的勘探战略。新大陆和火山构造研究将有助于减轻潜在的地震和火山灾害，最重要的是对人口稠密地区。

The dynamic evolution of the System Earth is chiefly controlled by internal generation and loss of energy, evident by plate-tectonic and magmatic processes, and external energy gain such as meteorite impact processes. An understanding of these processes, on variable length and time scales, underlies my research. Specifically, I propose to wok on: (1) analysis of fault systems and their effect on the activity of volcanic centres in the Central Andes (NW Argentina); (2) crustal deformation of orogenic belts, notably the Eastern Penokean Orogen (Ontario); and (3) formation of complex impact craters (Haughton, Devon Island, and Sudbury, Ontario). Because of their significance for geological hazard assessment and localizing natural resource deposits, these research fields have strong socio-economic importance. Key to all projects will be the visualization of the three-dimensional (3-D) structure of deformed rock volumes, restoration to their pre-deformational shapes, and analysis of deformation mechanisms. This approach promises to result in a better understanding of dynamic rock deformation from the mm- to the crustal scales, and on various time scales, more specifically, eruptive triggers of volcanic complexes, transport and emplacement of endogenic melts, stress accumulation, ore deposit genesis and impact crater formation. In the long run, I intend to close the gap between geological field and the numerical modelling studies by linking structural geological ground truth gleaned from process-oriented studies of natural laboratories with quantitative kinematic restoration of deformation and (analogue) modelling studies. This approach contributes also to generating more realistic models of rock deformation. My research on the formation and localization of ore deposits, addressed in collaboration with industry, will contribute to designing process-oriented exploration strategies. Neo- and volcanotectonic studies will help in mitigating potential seismic and volcanic hazards, most importantly for highly populated areas.
