The polymetamorphic evolution path of metapelites characteristic of the Algyo-Ferencszállás Metamorphic Complex of the Békés-Codru Unit (SE Hungary) is presented on the basis of microstructural and mineral paragenetic features, mineral chemical data and geothermobarometric calculations. The first (Variscan?) metamorphic event recorded by the Ca-rich part of zoned garnets from the Ferencszállás area is poorly defined, yielding conditions of 520-560 oC and 820-1010 MPa. This event was followed by a new tectonometamorphic phase that began with the formation of garnet, kyanite, muscovite, plagioclase and biotite. This younger (Alpine) event is marked by the decomposition of staurolite and biotite, and an increase in temperature and pressure. Peak metamorphic conditions reached c. 650 oC and 900 MPa in the Ferencszállás and Újszentiván areas. This P-T peak was followed by continuous decrease in temperature and pressure to c. 500-560 oC and 400-530 MPa. The P-T path calculations from the progressively zoned garnets of the Algyo area show an increase in temperature and pressure similar to the Ferencszállás area – but in shallower crustal depth – and yield 650-680 oC and 500-600 MPa for the metamorphic peak. This study, in combination with recently published geochronological data, presents the first record of Alpine amphibolite facies metamorphic overprint of the basement of the Tisza Unit, which was considered as not affected by medium-grade metamorphism younger than Variscan until now.
