The Marizal Formation is approximately 50m thick and consists of fluvial and alluvial fan deposits that gradually change from conglomerates to sandstones and mudstones. The researchers analyzed outcrops to identify nine basic architectural elements based on lithofacies, internal geometry, and contacts. They found that in proximal regions sediment gravity flows and gravel bars were predo
