The Biostratigraphy of Permian Palynofloras

Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1970
Abstract Classical paleobotanical theory separates the floras of the Permian Period into four distinctive provinces: (1) the Gondwanian; (2) the Angaran; (3) the Ca‐thaysian; and (4) the Euramerican. These floras are based on the stem and leaf remains which are the chief preservable macroscopic parts of plants.

Upper Permian Stratigraphy of West Texas Permian Basin

AAPG Bulletin, 1935
ABSTRACT By comparing the Upper Permian stratigraphy of West Texas and Oklahoma it is found that the Whitehorse of Oklahoma is equivalent to the lower evaporites of the southern basin and that the Permian of the Oklahoma Quartermaster is equivalent to the Yates sand.

Upper Permian Sediments in Southeastern Permian Basin, Texas

1968
Throughout most of late Permian time the southeastern Permian Basin was part of a shallow barred lagoon located in an area of high evaporation and low rainfall. Refluxion to the open sea farther west was slowed by the intervening Capitan barrier reef during Guadalupian time, but free surface influxion of sea water occurred.
