The ideal goal of biostratigraphic studies is to make stratigraphic ranges of all species clear
and to fix globally synchronous biohorizons as age controls. However, it is difficult to achieve …

This paper briefly summarizes current knowledge on water-depth indicators in Permian
radiolarians, and compares this knowledge with observational evidence for water-depth …

The current knowledge of Paleozoic radiolarian ranges, proposed zonations, and faunal
assemblages that have been used in biostratigraphy over the past few decades is compiled …

A major bio-crisis in the Guadalupian− Lopingian transition (Capitanian− Wuchiapingian,
middle− late Permian), possibly driven by the volatile eruption of the Emeishan large …

The Dongyang gold deposit is a recently discovered large gold deposit located within the
Dehua–Youxi–Yongtai mining camp in central–east Fujian Province, southeast China. The …

Large carbon cycle perturbations associated with the Middle Permian (Capitanian) mass
extinction have been widely reported, but their causes and timing are still in dispute. Low …

Abstract A late Kungurian (Cisuralian, Permian) fauna including conodonts and fusulines is
reported for the first time from the limestone units in the lower part of the Lugu Formation in …

The Guadalupian mass extinction was a long-term biocrisis that started in the early
Guadalupian Epoch (Permian Period). Many studies of the causes of the extinction have …

The Mianlue suture marks the southern boundary of the Qinling–Dabie orogen and divides
the South China and North China continental blocks. Here we present in-situ U–Pb …

The end-Permian mass extinction (EPME) was the most severe mass extinction event of the
Phanerozoic, and was associated with the development of global oceanic anoxia. The …
