The Late Carboniferous conglomerates of Tuppa Niedda (Arburese, SW Sardinia, Italy) (BARCA et alii, 1995a) have been analyzed in detail using facies analysis and depositional architecture procedures (MIALL, 1985, 1988, 1996). So, the splendid coastal outcrop has been minutely resolved into several architectural elements and sub-elements, each featured by precise lithofacies associations and linked to well-defined depositional processes. Its depositional environment was interpreted as to be a debris-flow dominated alluvial fan, in the following buried by stream flows produced by the distal part of a major alluvial fan. A comparison with similar, coeval sedimentological context has been attempted.

Abstract
The Late Carboniferous conglomerates of Tuppa Niedda (Arburese, SW Sardinia, Italy) (BARCA et alii, 1995a) have been analyzed in detail using facies analysis and depositional architecture procedures (MIALL, 1985, 1988, 1996). So, the splendid coastal outcrop has been minutely resolved into several architectural elements and sub-elements, each featured by precise lithofacies associations and linked to well-defined depositional processes. Its depositional environment was interpreted as to be a debris-flow dominated alluvial fan, in the following buried by stream flows produced by the distal part of a major alluvial fan. A comparison with similar, coeval sedimentological context has been attempted.
