Kinematics of rock deformation

系统地球的动力学演化主要受板块构造和岩浆作用等内部能量生成和损失以及陨石撞击等外部能量获取的控制。对这些过程的理解，在可变的长度和时间尺度上，是我研究的基础。具体来说，我建议工作：（1）断层系统的分析和它们对火山中心的活动在中央安第斯山脉（阿根廷西北部）的影响;（2）地壳变形的造山带，特别是东部Penokean造山带（安大略）;和（3）复杂的撞击坑（豪顿，德文郡岛，萨德伯里，安大略）的形成。由于这些研究领域对地质灾害评估和自然资源矿床定位具有重要意义，因此具有很强的社会经济意义。所有项目的关键将是变形岩石体积的三维（3-D）结构的可视化，恢复其变形前的形状，以及变形机制的分析。这种方法有望导致更好地了解动态岩石变形从毫米到地壳尺度，并在不同的时间尺度上，更具体地说，火山复合体的喷发触发，运输和内生熔体的就位，应力积累，矿石存款成因和撞击坑的形成。从长远来看，我打算关闭地质领域和数值模拟研究之间的差距，通过连接结构地质地面实况收集的过程为导向的研究自然实验室与定量运动学恢复变形和（模拟）建模研究。这种方法也有助于生成更真实的岩石变形模型。我对矿床的形成和定位的研究，与工业合作解决，将有助于设计过程导向的勘探战略。新构造和火山构造研究将有助于减轻潜在的地震和火山灾害，对人口密集地区最为重要。

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.
