    Experimental Study on the Pore Structure of Middle- and Low-Rank Coal and Its Influence on Methane Adsorption by Gaini Jia, Ming Yang, Xuebo Zhang, Lei Liu

    Published 2022-01-01
    “…Within 1 h of methane inflation, the methane adsorption capacity of middle-rank coals such as Henan Pingdingshan (PDS) and Shanxi Wangzhuang (WZ) and Xinjiang low-rank coals (XJ) increases by 36.4%, 31.7%, and 35.8%, respectively, and as the inflation time is extended to the cumulative inflation of 10 h, the order of the increase in methane adsorption capacity is still PDS>XJ>WZ. (2) The pore types of the experimental coal samples are mostly wedge-shaped pores and ink bottle-shaped pores. …”

    Isotopic Age of the Xiong’er Group Volcanic Rocks and Its Geological Significance in Western Henan, China by Wenchao Dong, Xucheng Pang, Weixun Qu, Guangshun Hou

    Published 2022-01-01
    “…The Xiong’er Group is mainly distributed in western Henan, southern Shanxi, and southeastern Shaanxi. As a set of low-grade metamorphic and low-deformation volcanic rocks formed in the transition period during the tectonic evolution of the North China Craton in the Precambrian, the tectonic and magmatic evolution information of this period are well recorded. …”
