Zuloaga formation (upper Jurassic) shoal complex, Sierra de Enfrente, Coahuila, northeast Mexico
The Zuloga Formation at Sierra de Enfrente may be divided into 7 interbedded carbonate facies. In order of abundance, they are: pell-ooid grainstone-packstone, lime mudstone, pelletal packstone-grainstone, ooid grainstone, pelletal wackestone, skeletal wackestone, and algal boundstone. Three measured sections located on an east-west trending, overturned anticline (Sierra de Enfrente) were described and sampled. The Zuloaga Formation sediments were deposited on a broad carbonate ramp dipping southward off the emergent Coahuila peninsula. The study area is located between Zuloaga-equivalent, near-shore, siliciclastic deposits to the north and outer-ramp Zuloaga lime mudstone facies to the south. This intermediate position was ideally situated for the development of high-energy shoals. Time-equivalent shoal facies that rim the Gulf of Mexico are prolific hydrocarbon producers (Smackover Formation, USA; San Andres Formation, Mexico).
