Abstract
This paper describes the structures observed on cores and image logs in AG10 well. The Aigion Fault architecture, including the damage zone, a 13 m-thick brecciated zone and fault core, are characterised. Structures predating the recent extension phase are numerous. Tectonic stylolites and sheared bed boundaries are related to the Hellenides compression trending ENE–WSW. The origin of bed parallel protobreccias and microstructures indicating east–west extension is discussed. These observations together with hydraulic data illustrate how image logs and cores can help us to understand the impact of tectonic fabric on fluid flow in carbonates. To cite this article: J.-M.
