Description
The Permian divides itself naturally into three series (Cisuralium, Guadalupium and Lopingium). In the classic area of the southern Urals, the Upper Carboniferous and Lower Permian (or Cisuralian) are well represented by marine deposits and abundant biota. This marine dominance disappears in the Kungurian, and the Middle Permian (or Guadalupian) and Upper Permian (or Lopingian) are dominated by terrestrialemarginal-marine deposits. The Guadalupian deposits of West Texas are dominated by diversified and well-studied marine fossil assemblages, and the deposits are the subject of seminal studies in sequence stratigraphy. China, Iran, and the Trans- Caucasian region are exemplary for their Upper Permian deposits and biota. The Guadalupian was first proposed by Girty at the turn of the last century for the spectacular fossils found in the Guadalupe and Glass Mountains of West Texas. These faunas have been well documented, and represent an unprecedented display in an exhumed, well-preserved backreef, reef, and basin facies. The West Texas depositional basins represent a tropical North American faunal suite, well removed from the more typical tropical Tethyan fauna of Asia and Europe. The Middle Permian was a time of strong provincialism and presents some complexities for correlation. The formal establishment of the Guadalupian and its constituent stages is based on the evolution of a single genus of conodont, Jinogondolella. The genus has a limited distribution, though it is common in West Texas and South China. The Guadalupian is divided into the Roadian, Wordian and Capitanian stages.
