Abstract. A new genus of the Corythoecidae (Albaillellaria, Radiolaria) was recovered from the Changhsingian (uppermost Permian) Dalong Formation in Guizhou Province, South China. Qiania Ito and Feng, gen. nov., containing Q. foremanae Ito and Feng, gen. et sp. nov. and Q. uncinata (Rudenko and Panasenko), is characterized by a conical shell consisting

To reconstruct the paleoenvironment, the petrography and geochemical compositions of the upper Permian Dalong Formation (Fm) (P3d) sandstones in the Central Uplift, South Yellow Sea Basin, was investigated, after which the provenance, tectonic setting, weathering conditions, and diagenetic history were determined.

Abstract The Late Permian was marked by a series of important geological events and widespread organic‐rich black shale depositions, acting as important unconventional hydrocarbon source rocks. However, the mechanism of organic matter (OM) enrichment throughout this period is still controversial.

Abstract A single species of fossil conifer with well-preserved cuticles from multiple layers of the Dalong Formation in two sections in Duanshan Town, Guizhou Province, Southwest China has been used to reconstruct palaeo-atmospheric pCO2. The age of these layers can be dated back to the late Changhsingian (latest Permian), corresponding to the ...

Abstract The major processes responsible for the interplay of hydrothermal influence and paleo-depositional environments (paleoproductivity and plaeoredox condition) on the accumulation of organic matters can be better understood by integrating lithological and geochemical characteristics of samples from the well exposed Late Permian sediments in the

Abstract The Upper Permian Dalong Formation in the northeastern Sichuan Basin contains organic-rich siliceous shales deposited in the Kaijiang–Liangping Trough, but the relative roles of productivity, redox conditions, and nutrient supply in organic matter enrichment remain debated.

A quantitative reconstruction method of paleo-primary productivity is present on the basis of the investigation on the faunal record in cherts. By obtaining the accumulation rate of radiolarian shells in the cherts and considering all aspects of silica loss before burial, such as dissolution in the eutrophic zone or within the sediments, it is possible

ABSTRACT Organic‐rich shales of the Upper Permian Dalong Formation in the Western Hubei Trough represent a potential successor interval for shale‐gas exploration in the Middle–Upper Yangtze region, yet their depositional evolution and organic‐matter enrichment mechanisms remain incompletely understood.
