In the second phase (the current proposal), all resources will be used to tackle the construction of the 3D model for the highly composite and complex study area, in order to understand the mechanisms of salinization processes below the TB and in particular in the HTR in relation to faults and tectonic features of the basin. Eventually, the current suggested proposal will result in the presentation of the first regional model of density driven flow for the study area. While the 2D and preliminary 3D models already provide insights into the possible transport mechanisms, it is clear that 3D modeling on real structural data will provide a better understanding of the hydrologic processes related to heat and brine migration in faulted basins. Although the 2D models are physically correct, faulted geothermal systems are complex and display huge geological and physical variability. A consequence of this complexity is that several 2D models will not provide a full picture of the system as it is impossible to study the interactions and coupling between the different 2D patterns.As explained in the submitted manuscript (enclosed in the appendix), convective patterns are most likely 3D and need to be addressed in a full 3D model. The preliminary 3D models currently investigated confirmed this aspect (see 3D abstracts).A major goal will be to adapt structural, physical and chemical properties to the 3D requirements of the numerical model. To tackle this problem, (T3) will provide a first regional model of the area allowing (T1) to build preliminary 3D numerical models based on real structural data. The geological model will be permanently refined in a block-wise manner, i.e. major geological/structural boxes will be identified according to natural features of the system (faults, folds, layering etc), hydro-geochemical data (T3 and T2) and updated numerical results (T1). This will require a well-planned co-ordination of the multi-disciplinary approach described above. By now the 2D and preliminary 3D models are completed and show several convective regimes (see enclosed article) and the open question that needs to be addressed are:- How do the 2D patterns develop in 3D?- How can we correctly apply adimensional theory (e.g. Rayleigh, Nusselt) to predict the onset of 3D convection in faults and surrounding units? - Under which conditions convective patterns can still be considered purely 3D or 2D?Solving all these key points will explain:- The driving mechanisms of active flow transport processes in faulted systems- The observed temperatures of brines and their chemical differences within the TB, mainly between the western sources and eastern part of the HTR. - The study of 3D convective patterns and the role of fractures and more permeable zones on deep fluid flow, their influence on the mass and energy migration system.

在第二阶段(目前的提议)，所有资源将用于为高度综合和复杂的研究区建造3D模型，以了解TB以下盐碱化过程的机制，特别是HTR与断裂和盆地构造特征的关系。最终，目前建议的提案将导致提出研究区域的第一个密度驱动流区域模型。虽然2D和初步3D模型已经提供了对可能的输运机制的洞察，但很明显，基于真实构造数据的3D建模将更好地理解与断陷盆地中的热和卤水迁移有关的水文过程。尽管2D模型在物理上是正确的，但断层地热系统是复杂的，并显示出巨大的地质和物理变异性。这种复杂性的结果是，几个2D模型无法提供系统的全貌，因为不可能研究不同2D模式之间的相互作用和耦合。正如提交的手稿(附在附录中)所解释的那样，对流模式很可能是3D的，需要在完整的3D模型中进行处理。目前研究的初步3D模型证实了这一点(见3D摘要)。一个主要目标将是使结构、物理和化学特性适应数值模型的3D要求。为了解决这个问题，(T3)将提供该地区的第一个区域模型，允许(T1)基于真实的结构数据建立初步的3D数值模型。地质模型将以块状方式永久细化，即将根据系统的自然特征(断层、褶皱、分层等)、水文地球化学数据(T3和T2)和更新的数值结果(T1)来识别主要的地质/构造盒。这将需要对上述多学科方法进行有计划的协调。到目前为止，2D和初步3D模型已经完成，并显示了几个对流模式(见所附文章)，需要解决的悬而未决的问题是：-2D模式如何在3D中发展？-我们如何正确地应用一维理论(例如Rayleigh，Nusselt)来预测断层和周围单元中3D对流的开始？-在什么条件下，对流模式仍然可以被认为是纯3D或2D的？解决所有这些关键点将解释：-断层系统中活动流动输送过程的驱动机制-观测到的卤水温度及其在TB内的化学差异，主要是在HTR的西部源和东部之间。-研究三维对流模式以及裂缝和更具渗透性的区域对深层流体流动的作用，以及它们对质量和能量迁移系统的影响。
