Conclusions

[41]  The fusulinid assemblage from the Khan Formation shows close similarity with the Kalaktash one of Central Pamirs and thus can be dated as Sakmarian.

[42]  Previously Sakmarian deposits have not been recorded in the Iranian territory. Supposed Sakmarian age of the Dorud (Alborz) and Vazhnan (northern Zagros) formations has not be confirmed by recent fusulinid finds. They are most likely Asselian.

[43]  The fusulinid assemblage of the Khan Formation is characteristic of the Peri-Gondwana South Tethyan province of relatively high paleolatitudes and essentially different from fusulinid associations of the near-equatorial North Tethyan province. The Asselian fusulinids of Iran are similar to the warm-water North Tethyan assemblages. The recent neighboring location of Asselian warm-water and Sakmarian relatively cool-water assemblages is surprizing, the more so as they demonstrate no inherence.
