| Summary: | a base-of-slope apron with consistent thickness and facies basin areas as lobate carbonate sand bodies that thin and become muddier both along strike and downdip. Internal bedded, skeletal-spiculitic mudstone/wackestone and carbonate sand was transported to outer portions of the ramp deposition. The Nunn-Tierra Blanca interval consists of thin distribution along depositional strike. In contrast, the exposures along the dip-trending western escarpment of the facies components within the Alamogordo-Tierra Blanca flow processes, particularly by debris flows and sandy debris flows, was dominant during Nunn Tierra Blanca time. The from a series of discrete point sources located (but no grade laterally and downdip into thin to medium bedded lesser amounts of massive, lithoclastic-skeletal grainstone lobate morphologies and lateral facies distributions within Lobate morphologies further suggest that shallow-water longer exposed) updip of the study area. low-relief (<50m synoptic relief), km-scale (laterally), mud mounds were mostly initiated during Alamogordo Nunn-Tierra Blanca interval prograded into outer ramp-to- of carbonate platform margin and slope facies is commonly of sedimentation, erosion and sediment bypass.
