The Raton basin is bounded on the west by the ancestral San Luis highlands. The highlands were probably uplifted along a highangle reverse fault zone marginal to the basin. Coarseningupward megacycles and types of facies sequences and facies associations within the Upper Cretaceous Vermejo Formation and Upper Cretaceous and Tertiary Raton and Poison Canyon Formations indicate that both allocyclic and autocyclic mechanisms influenced alluvial sedimentation in the Raton basin. The megacycles comprise a coalrich, fine detritusdominated facies and an overlying coalpoor, sanddominated facies. The coalrich, fine detritusdominated facies was deposited by braided, meandering, and anastomosed fluvial systems during periods...

Recent Developments in Fluvial Sedimentology
This volume brings together 36 of the manuscripts that were presented at the Third International Fluvial Sedimentology Conference hosted by Colorado State University in August, 1985. Fluvial systems and sedimentary rock sequences discussed range in age from Holocene to Precambrian and include many diverse areas. The principal objective of the volume was to document the recent developments in the application of facies analysis to the reconstruction of the architecture of fluvial systems. Reconstruction of architecture is an integral part of the overall process of basin analysis.
