Study on sedimentary facies characteristics of Xujiahe Formation in Sichuan Basin [PDF]
E3S Web of Conferences, 2021 Sedimentary facies is the summation of all primary sedimentary features in a sedimentary unit, which is the product of sedimentation in a specific environment. It emphasizes the material performance of sediment formation conditions, including mineralogy,

Relationship between stratigraphic overlap and sedimentary facies evolution of the Junggar Basin, Northwest China [PDF]
Scientific ReportsThe interaction between the topography of the slope zone on the edge of the basin and the distribution of sediments is crucial for accurately predicting sediment distribution, but few studies emphasize the impact of stratigraphic overlap on the spatial ...

Explainable artificial intelligence for sedimentary facies segmentation. [PDF]
Sci RepRecent advances in artificial intelligence are transforming geosciences, with growing attention on explainable models to support both scientific research and practical adoption. Here, we present a general yet tailored pipeline for semantic segmentation of sedimentary facies from Holocene core images.
