Abstract

Based on mineral associations determined in high - temperature muscovitic gneisses of the Valandovo - Bogdanci low ­ pressure metamorphic complex two metamorphic zones are distinguished: andalusite - muscovite and sillimanite - muscovite - K ­ feldspar. Mineral associations distinguished for andalusite - muscovitic zone indicate T from 570 to 610 °c and P = 3.5 - 3.75 Kb, whereas for sillimanite - muscovitic -K -feldspar higher T ranging from 650 to 670 °c and P = 3.5 -3.75 Kb . The occurrence of high - temperature low - pressure rocks in a wide elongated belt point to typical Abakuma type of regional metamorphism.
