Photos of the primary facies in Brousse-Broquiès basin including abiogenic chert (A,C), fissile bentonite (A,B), and tuffaceous silt-sandstone (D). Chert beds internally display abundant micrograding of fine (< 2 mm) pumice/lapilli (C), convolute bedding (F), and abundant soft sediment deformation (E,G). Ripples, hummocky cross stratification, and coarse (0.5–3 cm) lapilli are preserved on bedding planes (H–I). Tuffaceous sandstones (D) have rip-up clasts of chert and volcanic fragments.
