Effects of mineral distribution at mesoscopic scale on solute diffusion in a clay-rich rock: Example of the Callovo-Oxfordian mudstone (Bure, France)

Autor: D. Coelho, Jean-Charles Robinet, Jean-Claude Parneix, Elodie Boller, Dimitri Prêt, Paul Sardini, Stéphane Sammartino, Scott Altmann

Publikováno v: Water Resources Research. 48

[1] The mesostructure (millimeter to micrometer scale) of clay-rich sedimentary rocks is generally characterized by a connected fine-grained clay matrix embedding coarser nonclay minerals. We use the Callovo-Oxfordian clay-rich rock formation (France

Les paragenèses de remplacement des biotites utilisées comme marqueurs des conditions de température et de composition des fluides dans les altérations hydrothermale et supergène du granite de Mayet-de-Montagne (Allier, France)

Autor: Alain Meunier, Jean-Claude Parneix

Publikováno v: Bulletin de Minéralogie. 105:662-672

This study concerns the alteration facies of biotite in Mayet-de-Montagne granitic rock (29 samples selected from 150 meters of INAG drilling). Secondary phases were identified by X-ray diffraction and located optically in thin section. Microprobe (C
