An insect wing discovered in the Early Permian Taiyuan Formation (Shanxi Province, China) [PDF]
Fossil Record, 2019 The first discovery of an insect wing from the Taiyuan Formation, near Yangquan City, Shanxi Province, China, is described. The combination of its wing venation characters makes it difficult to assign it to any known major Paleozoic group. The comparison

Controls on the Organic Matter Accumulation of the Marine-Continental Transitional Shanxi Formation Shale in the Southeastern Ordos Basin. [PDF]
ACS Omega, 2022 The marine-continental transitional shale with favorable geological conditions for shale gas accumulation and broad resource prospects is widely distributed in China, which is also well developed in the Ordos Basin. The reservoir characteristic and gas-bearing properties of the transitional Shanxi Formation shale have been studied in previous studies ...

Formation and Development of Pore Structure in Transitional ShaleInsights from Thermal Simulation Experiments on the Shanxi Formation Shale in the Ordos Basin. [PDF]
ACS OmegaTransitional shale gas reservoirs have become a new field of shale gas exploration in China. However, the formation and evolution of shale pores, particularly the organic matter (OM) nanopores, in this type of shale are still unclear. Simulation experiments with a typical transitional shale were conducted, and field emission scanning electron ...

Numerical simulation of formation and preservation of Ningwu ice cave, Shanxi, China [PDF]
The Cryosphere, 2015 Abstract. Ice caves exist in locations where annual average temperature in higher than 0 °C. An example is Ningwu ice cave, Shanxi Province, the largest ice cave in China. In order to quantitatively explain the mechanism of formation and preservation of the ice cave, we use Finite Element Method to simulate the heat transfer process at this ice cave ...

, 2023 Abstract As a variety of microbial carbonates, oncoids exhibit characterstics of coated grains that have relative large size than ooids with microbial origin, and features of successive lamination similar to stromatolites. The present study is aimed at investigation of formation of the Cambrian oncoids that developed in top part of the Zhangxia
