REGIONAL TYPOLOGY OF ZIRCON AND ITS RELATIONSHIP TO ALLANITE/MONAZITE ANTAGONISM (ON AN EXAMPLE OF HERCYNIAN GRANITOIDS OF WESTERN CARPATHIANS)

Rok, strany: 1991, 271 - 277

The paper demonstrates the posibilities of an application of Pupin's typological analysis of zircon to petrogenesis of granitoid rocks. The study of zircons from Hercynian granitoids of various types and units of the Western Carpathians resulted in the determination of regional zoning of Hercynian granitoid intrusions related to the increase of the parameters I. T and I. A in the direction from external to internal units of the Western Carpathians. Besides this, the zircon typological parameter I. T is higher in allanite than in monazite granitoid types, which is consistent with the higher-temperature origin of allanite granitoids in comparison with monazite varieties.
