内容記述 | This paper reports on preliminary results of the CHIME (chemical Th-U-total Pb isochron method) dating of detrital monazites from sandstone samples of the Upper Silesia Coal Basin. A total of 1012 spots on 203 monazite grains were dated for the Poruba Beds of the Namurian Paralic Series (sample POR1/12), and a total of 1060 spots on 212 monazite grains for the Stephanian Kwaczala Arkose (sample KA1/12). The ages of detrital monazite grains in POR1/12 cluster around 300 Ma with subordinate concentrations around 330 Ma, 360 Ma, 420 Ma and 530 Ma. Most monazite grains in KA1/12 have ages that range from 310 Ma to 330 Ma, and the rest yield a c. 300 Ma age. Monazite grains older than 360 Ma are rare in KA1/12. Although c. 300 Ma monazite ages are inconsistent with the Namurian fauna age for the Poruba Beds, the predominance of 300-330 Ma detrital monazites suggests a very fast denudation of the crystalline source areas. A major source area may be the Variscan lithologies of the Bohemian Massif. | |||||
