BoDy - Boudinage Dynamics

我们建议使用最先进的离散元和有限元模型，结合对世界级露头的高分辨率实地研究，以更好地了解石香肠的演化。我们将测试现有的运动学模型的机械有效性，并旨在开发一个新的税收-经济学诊断标准的基础上，一个完整的和一致的力学理解的石香肠。该项目的目标是建立观测反演，以获得石香肠形成过程中的流变学、应力、应变和涡度信息。该项目的重要性是双重的。通过在自然实验室提供关于流变学、有效应力、应变和涡度的数据，它将改进地壳力学演变的模型。实际应用是在盐中包裹的矿床和油气藏的勘探中，防止在碳酸盐岩中的钻井问题，以及在潜在的核废料储存地点预测石结硬石膏层的结构。

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.
