The Smeltertown Formation is a geologic formation in New Mexico, which is particularly well exposed at Cerro de Cristo Rey near El Paso, Texas. It preserves fossils dating back to the early Cretaceous period.[1]
The formation consists of gray shale with some interbedded siltstone and silty limestone, with some fine grained sandstone towards the top of the formation. The total thickness is 193 feet (59 m). It rests conformably on the Del Norte Formation and is conformably overlain by the Muleros Formation.[1]
