abstract = "We performed a joint analysis of SHRIMP II U-Pb ages (68 measurements for 5 rock types) and trace and rare-earth element compositions of zircons (41 determinations made in the same points that were utilized for measurement of U-Pb isotope ratios) from the complex Orekhovo-Pavlograd shear zone of the Ukrainian Shield. It was determined that this zone is composed of rocks of different age: 3.5, 3.4, 2.8, and 2.0 Ga. The main stage of structural-metamorphic reworking took place 2.0 Ga and lasted for over 30 Ma. It was established that fluid reworking of zircons was accompanied by an increase of LREE content and decrease of Ce anomaly. The preservation of U-Pb system in some zircons with high LREE contents may be explained by their solid state transformation.",
