Abstract (in english)
   The Klenov massif forms an independent NE-SW trending body within the Moldanubian batholith and is separated from the main body of this batholith by metamorphic rocks of the monotonous group of the Moldanubian zone. The principal rock type of the Klenov massif are two-mica granites of the Deštná subtype. Granites of this subtype obviously postdated the porphyric two-mica grantes of the Číměř subtype. The granites of the Deštná subtype are closely associated with aplite granites and aplites which represent the youngest variety of granites of the Klenov massif. All varieties of the granites are typical peraluminous granites. A notable differentiaton in the Rb/Sr ratio, the absence of negative Eu anomaly and a low value of the Th/U ratio are typical for the granites of the Deštná subtype. Granites of the Klenov massif were derived by partial melting of metamorphic rocks related in their composition to the Moldanubian biotite paragneisses with a varying garnet content.
   The ganiotes to granodiorites of the Švětín type can be assigned to the Freistadt-type granodiorites
