Lithology and environment
Primary lithology: | "limestone" |
Lithology description: The formation is generally composed of calcarenite or shell debris or both. At the type locality it attains a thickness of about 221 feet, but it is thinner to the southwest along the same belt and also in the northern belt. One of the best places for the study of this formation is at the Porterfield Quarry, 5 miles east of Saltville. At this place the Effna formed a great reef (now quarried away) at the base of the Rich Valley formation. | |
