Abstract

Analogue modelling of wrench tectonics typically utilizes a rigid basement with a velocity discontinuity under a brittle or brittle-viscous cover, such as in Riedel experiments, which confines fault localization in the overlaying model. However, such a set-up is hardly compatible with modeling brittle-ductile systems such as the upper and lower crust or a brittle sedimentary cover overlying a viscous evaporitic layer. To achieve a more realistic experimental approach, Bruno Vendeville designed an alternative experimental set-up decoupling the basement from the brittle overburden with a viscous layer in which the basement is not involved. In this configuration, strike-slip movement is driven laterally rather than from the base up, facilitated by “weak zones” that preferentially localize the deformation during shortening and enable sliding between compartments. This original approach provides greater flexibility for modeling complex strike-slip settings, allowing for more freedom for strike-slip structures to form and evolve through time.

Although the experiments described in this work were conducted in the late 1990s, the co-authors have chosen to revisit and adapt this earlier work for this Special Issue to underscore Bruno's influence on another aspect of salt tectonics and his pioneering foresight in the field of analogue modelling.

在粘性层上方生成扳手区的另一种实验配置
扳动构造的模拟建模通常采用脆性或脆性-粘性覆盖层下的速度不连续的刚性基底,如 Riedel 实验,这就限制了叠加模型中的断层定位。然而,这种设置很难与脆-韧性系统建模兼容,例如上地壳和下地壳或覆盖在粘性蒸发层上的脆性沉积覆盖层。为了实现更真实的实验方法,Bruno Vendeville 设计了另一种实验装置,将基底与脆性覆盖层解耦,并在基底上设置一个粘性层。在这种结构中,击滑运动是由横向而不是由基底向上驱动的,"薄弱区 "在缩短过程中优先将变形局部化,并使隔间之间的滑动成为可能。虽然这项工作中描述的实验是在 20 世纪 90 年代末进行的,但共同作者选择在本特刊中重新审视和调整这项早期工作,以强调布鲁诺对盐构造的另一个方面的影响,以及他在模拟建模领域的先见之明。

期刊介绍: The Journal of Structural Geology publishes process-oriented investigations about structural geology using appropriate combinations of analog and digital field data, seismic reflection data, satellite-derived data, geometric analysis, kinematic analysis, laboratory experiments, computer visualizations, and analogue or numerical modelling on all scales. Contributions are encouraged to draw perspectives from rheology, rock mechanics, geophysics,metamorphism, sedimentology, petroleum geology, economic geology, geodynamics, planetary geology, tectonics and neotectonics to provide a more powerful understanding of deformation processes and systems. Given the visual nature of the discipline, supplementary materials that portray the data and analysis in 3-D or quasi 3-D manners, including the use of videos, and/or graphical abstracts can significantly strengthen the impact of contributions.
