U-Th-rich zircon, thorite and allanite-(Ce) as a main carriers of radioactivity in the highly radioactive ultrapotassic melasyenite porphyry from the Šumava Mts., Moldanubian Zone, Czech Republic

Original language description

A melasyenite porphyry from the vicinity of Kašperské Hory (the Šumava Mts., Moldanubian Zone) shows a high natural radioactivity (K = 4.4-6.1 wt. %, eU = 15-24 ppm, eTh = 38-49 ppm). The most important carriers of U and Th are zircon, thorite, allanite-(Ce) and scarce monazite. Most of the zircon and thorite grains are altered by post-magmatic processes of due to which especially the zircon shows a large degree of chemical variability.
