Abstract

Along-strike segmentation of orogens raises questions because its causes may predate orogeny in relation to structural inheritance. Here we focus on rift/margin linkage domains and their inversion by using analogue models with image analysis to extract the 3D strain field. Extensional models document, depending on the strike-perpendicular offset and the brittle-crust thickness, three types of rift linkage modes: (1) oblique linkage with early T-fault, (2) strongly-oblique linkage with R-fault network and, (3) transfer-linkage with late Y-strike-slip fault. Analogue model of inverted rift basins is used to analyse the misunderstood tectonic evolution of transition zones in the segmented Western Alpine belt.

裂谷联动的模拟模式及反演及其在西阿尔卑斯的应用

造山带的沿走向分段引起了人们的疑问，因为它的成因可能早于造山带的构造继承。本文重点研究了裂谷/边缘连接域及其反演，利用模拟模型结合图像分析提取三维应变场。伸展模型根据走向垂直偏移量和脆壳厚度的不同，记录了三种断裂联动模式:(1)与早期t型断层的斜联动，(2)与r型断层网络的强斜联动，(3)与晚期y型走滑断层的转移联动。利用逆裂谷盆地模拟模型，分析了西高寒带分段过渡带构造演化的误解。

期刊介绍： Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
