The East Inman Consolidated Field, discovered in 1940, produces from the Tar Springs as well as from several other Chesterian cyclic sandstones.
Beverly Seyler was particularly helpful in the scanning electron microscopy/energy dispersive x-ray analyses and interpretation of the Tar Springs samples, along with advice on thin-section preparation.
If not, then at least one of them must be physically out of context.
Does anyone have a photograph of the bedroom of Edison Chen?
