Shales with their large clay fraction are prone to deform in an almost ductile way under tectonic loading. Here, we propose to monitor and quantify the evolution of strained shales clay fabric in the field of illite diagenesis by using magnetic fabri

AMS of strained shales fragments: a fast way to quantify the matrix damage

Autor: Tiphaine Boiron, Charles Aubourg, Antonio M. Casas-Sainz, Francho Gracia-Puzo

With the objective of mapping strain around a thrust front in an orogenic context (Pyrenean Range), 757 shale fragments (0.7-6.2 g) have been collected in 49 sites. Scalar data (degree of anisotropy P and shape parameter T), together with ellipse of

Representativeness of volume investigated by high-resolution X-ray computed tomography in damaged fine-grained rocks

Autor: Tiphaine Boiron, Hannelore Derluyn, Peter Moonen, Charles Aubourg, Pascale Sénéchal, Hugo Saur

We focus on calcareous homogenous shales featuring different degrees of damage along a km-long strain gradient, marked by cleavage development. In a previous study, we used high-resolution X-ray computed tomography (µCT) to document the evolution of

International audience; We document the evolution of the 3D fabric of shale along a km-long strain gradient in the Jaca basin (Southern Pyrenees, Spain). With respect to the distance from a thrust, samples were collected in the cleavage-free domain,
