This paper presents new zircon U–Pb ages and Hf isotope data, and whole‐rock major and trace element geochemical data of Permian igneous rocks from the eastern Songnen Massif (SM) and the western Jiamusi Massif (JM), NE China, to constrain their tectonic

Mercury evidence of intense volcanic effects on land during the Permian-Triassic transition
Geology, 2019The Siberian Traps large igneous province (STLIP) was the likely trigger for the ca. 252 Ma latest Permian mass extinction (LPME), but direct evidence for global volcanic effects on land remains rare. Here, we used mercury (Hg) enrichments, a proxy for

Abstract Permo-Triassic carbonates with minor basal clastics cover extensive tracts of the Shan Plateau in the eastern part of Myanmar. These carbonates are grouped into the Permian Thitsipin Limestone Formation and the Late Permian–Early Triassic Nwabangyi Dolomite Formation.

The composition of Permian seawater
Geochimica et Cosmochimica Acta, 1991Forty-nine brine inclusions in marine halite from the Ochoan Salado Formation in the Delaware Basin and fifteen inclusions in halite from the Leonardian Wellington Formation in the Kansas Basin were extracted, and their chemical compositions were determined.

The first question concerning the Permian of China is, “Where in the world…?” Agreement is general that China consists of a maze of blocks or terranes, amalgamated along complex sutures and fold belts (Fig. 1). There is, understandably, considerably less agreement on where they originated and their history of amalgamation (Table 1).

Upper Permian Stratigraphy of West Texas Permian Basin [PDF]
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. Formations above the Yates in the southern basin are younger than any of the Oklahoma or Kansas

The Biostratigraphy of Permian Palynofloras
Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1970Abstract 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.
