Paleopiezometry provides an access to the past stress magnitude, key to better understand the behaviour of the earth's crust over long period of time. This contribution presents a review of some paleopiezometric techniques that can be used in the diagenetic domain, in fold-and-thrust belts and sedimentary basins. Calcite twinning and stylolite roughness techniques have been selected and are presented through a critical description of their methodologies, along with approaches to further reconstruct the complete effective stress tensor. Major geological lessons learned over the past decades from published studies are summarized and discussed along with a way forward to potential breakthroughs.
