| 摘 要： | Tonstein layers are found worldwide in the Permo–Carboniferous coal-bearing strata. This study investigates the geochronology, mineralogy, and geochemistry of four tonstein samples from the Permo–Carboniferous Benxi Formation, Ordos Basin, North China Craton(NCC). The typical features of the studied tonsteins include thin beds, lateral continuity, angular quartz grains, and euhedral zircons with similar U-Pb ages, indicating a significant pyroclastic origin. In addition, the tonstein samples hav...
