Photomicrographs of the main facies observed in the Kimmeridgian–Tithonian limestones of the Geneva Basin. a packstone to grainstone facies in the Calcaire de Tabalcon unit; b dolomitized boundstone in the Calcaires de Tabalcon unit; c medium sized, fabric destructive, sucrosic dolomite in the Calcaires de Tabalcon unit; d wackestone with microsolenoid coralsin the Calcaires Récifaux unit; e oncoid grainstone with calcite spar cement in the Calcaires de Landaize unit and f fine to medium sized, fabric destructive, sucrosic dolomite in the Tidalites de Vouglans unit. On the left, the complex, vuggy, porosity is filtered in red and amounts to 12.5% of the total image
