This hybrid interval includes a "Kashtak Fm Lurestan". (a) Jahrum Fm - Basal 100 feet is massive, brown-weathering dolomite which is overlain by 535 feet of medium-bedded, relatively low weathering dolomite, Upper 100 feet is massive, feature-forming, dolomitic limestone with abundant microfauna. And the coeval (b) Pabdeh Fm - 2620 feet of low-weathering gray shale and thin argillaceous limestone were measured. Purple shale member at the base of the Pabdeh consists of silty to sandy, purple-red-gray shale. Thin-bedded argillaceous limestone containing fish scales and chert makes up the Taleh Zang formation. (In the paper, Pabdeh and Jahrum are described as two separate formations, while, the chart displays them as two different members of the same formation. (The spelling on the chart is Padeh, while, in the paper is Pabdeh.)
