Abstract (in english)
   The Čistá-Jesenice pluton forms a large elongated body (over 1000 sq. km) in the Teplá-Barrandian zone of the Bohemian Massif. It consists predominantly of the Tis biotite granite which intruded into an anticlinorial zone of Upper proterozoic rocks probably during Late Cambrian (or Early Ordovician?). This granite body was later penetrated by the Čistá granodiorite stock during Early Devonian and deeply eroded and extensively exposed before Late Paleozoic. The Tis granite and Čistá granodiorite were later affected by processes of alkali metasomatism (fenitization) connected with hypothetical carbonatite magmatism, in the contact zone of both the granite and granodiorite intrusions. Mylonitization, fenitization and feldspathization, which occured at the contact of granite and granodiorite and on radial faults in the granodiorite body, carry a Mo-Zr-REE mineralization. During Late Carboniferous the whole pluton was covered by continental sediments.
   The pluton crops out in several isolated areas only (Tis, Jsenice-Oráčov, Petrohrad and Čistá). The granite pluton of Late Cambrian age and the Early Devonian Čistá granodiorite body differ in their geophysical, structural, and geochemical characteristics
