Abstract

Regarding the problem of the age the Pelagon, two questions can be asked: the first question is the
age of the metamorphic rocks (??) and the second one is the age of the consolidation of the massif (?). The metamorphic
complex of the Pelagon is polymetamorphic and polydeformational, and the age of the oldest relics has not been deter�mined yet. This information paper for the first time presents information about determining the age of metamorphic
rocks using the U / Pb method of samples representing titanites from the lower metamorphic complex (gneisses). The
information obtained indicates an age in the range of about (1840 ±25 m / y. This is the first information that has been
received and, in any case, it should be rechecked in some further research. The second question concerning the age of
the consolidation of massifs has been documented in more detail in almost all crystalline massifs on the Balkans and
that age ranges from about 550 to 600 million years, and this consolidation ends with an intense granitic (Herzinian)
magmatism of about 300 million years of age.
