This study analyzes the fracture network at different scales in the Lower Jurassic limestones outcropping in the Agourai plateau, Middle Atlas, and their relationship with karst structures. This zone belongs to the Sub-Tabular Middle Atlas belt, called “Causses Moyen-Atlasiques”. This area underwent a polyphased tectonic evolution, involving karst depressions aligned NE-SW parallel to the main faults. The approach is based on the fracturing analysis and the determination of relationships between tectonic events and the main karstic structures development, corresponding to aligned dolines forming important uvala systems. We analyze the karst distribution along the main faults affecting Liassic carbonates and we describe some karst sedimentary fill.

Abstract
This study analyzes the fracture network at different scales in the Lower Jurassic limestones outcropping in the Agourai plateau, Middle Atlas, and their relationship with karst structures. This zone belongs to the Sub-Tabular Middle Atlas belt, called “Causses Moyen-Atlasiques”. This area underwent a polyphased tectonic evolution, involving karst depressions aligned NE-SW parallel to the main faults. The approach is based on the fracturing analysis and the determination of relationships between tectonic events and the main karstic structures development, corresponding to aligned dolines forming important uvala systems. We analyze the karst distribution along the main faults affecting Liassic carbonates and we describe some karst sedimentary fill.Pubblicazioni consigliate
