BoDy - Boudinage Dynamics

我们建议使用最先进的离散元和有限元模型，并结合对世界级露头的高分辨率实地研究，以更好地了解边界的演变。我们将测试现有的运动学模型的机械有效性，并旨在基于对束缚的完整和一致的机械理解，开发一种具有诊断标准的新税收经济。这个项目的目标是建立对观测的反演，以获得在结合过程中流变学、应力、应变和涡度的信息。这个项目的重要性是双重的。通过提供自然实验室的流变学、有效应力、应变和涡度数据，它将改进地壳力学演化模型。它的实际应用包括勘探被盐包裹的矿床和碳氢化合物储层，防止蒸发岩的钻探问题，以及预测潜在核废料储存地点的边界硬石膏层的结构。

We propose to use state of the art Discrete Element and Finite Element models integrated with a high-resolution field study of a world-class outcrop, to better understand the evolution of boudins. We will test existing kinematic models for their mechanical validity, and aim to develop a new tax- onomy with diagnostic criteria based on a complete and consistent mechanical understanding of boudinage. The goal of this project is to build towards an inversion of observations to obtain informa- tion on rheology, stress, strain, and vorticity during the formation of boudins.The importance of this project is twofold. By providing data on rheology, effective stress, strain and vorticity in natural laboratories, it will improve models of the mechanical evolution of the crust. Practi- cal applications are in the exploration of ore deposits and hydrocarbon reservoirs encased in salt, prevention of drilling problems in evaporites, and prediction of the structure of boudinaged anhydrite layers in potential sites for nuclear waste storage.
