    Effects of Igneous Intrusion on Microporosity and Gas Adsorption Capacity of Coals in the Haizi Mine, China by Jingyu Jiang, Yuanping Cheng

    Published 2014-01-01
    “…The results show that the thermal evolution of the sill obviously changed the coal geochemistry and increased the micropore volume and adsorption capacity of heat-affected coal (60–160 m from the sill) compared with the unaltered coals. …”

    Groundwater Quality Assessment in a Karst Coastal Region of the West Aurunci Mountains (Central Italy) by Giuseppe Sappa, Silvia Iacurto, Flavia Ferranti, Francesco M. De Filippi

    Published 2019-01-01
    “…Results suggest that carbonate weathering, ion exchange, and seawater intrusion in this karst coastal region are the major factors controlling groundwater geochemistry. This study shows that groundwater quality assessment, based on hydrogeochemical investigation techniques, has been a useful tool to characterize and model carbonate aquifers in Central Italy, with the aim of achieving proper management and protection of these important water resources.…”

    Monitoring of Technical Condition of Buildings by Seismic Method by Alena A. Kurdanova, Mikhail N. Voskresenskiy, Elena A. Kosorotova, Gennadiy I. Parygin

    Published 2024-12-01
    “…According to the results of annual monitoring (since 2017), the stable state of the Institute of Geophysics building of UB RAS is demonstrated, and a comparison with resonant frequencies obtained from the standard project (Institute of Geology Geochemistry of UB RAS) is presented. This article presents a method for assessing seismic stability by calculating horizontal acceleration ( ) at observation points. …”

    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
    “…Combined with previous studies on isotope and rock geochemistry of volcanic rocks in the Xiong’er Group, it was believed that the formation ages of the volcanic rocks of the Xiong’er Group are between 1874 and 1618 Ma, among the ages of the Xushan Formation, Jidanping Formation, and Majiahe Formation, which were concentrated between 1874 and 1800 Ma, 1836 and 1711 Ma, and 1780 and 1618 Ma, respectively. …”
