    Multiple equilibrium stages were identified from garnet-rich gneiss at Ktiš in the Lhenice shear zone of the southern Bohemian Massif, Czech Republic. The matrix of the rock mainly comprises cordierite (Crd), sillimanite (Sil), biotite (Bt), garnet (Grt), quartz (Qtz), K-feldspar (Kfs) and plagioclase (Pl) along with accessory minerals such as spinel (Spl), apatite (Ap), monazite (Mnz) and zircon (Zrn). Bt, Sil, kyanite (Ky)and Pl occur as inclusion phases in Grt. Some coarse-grained (N3 mm)Grts show chemical heterogeneity both in major and trace elements. Grossular (Grs)-content is homogeneous and high {Xgrs=Ca/(Ca+Mg+Fe+Mn)=0.27} in a center of the grain and smoothly decreases towards the grain margin (Xgrs=0.02). However, pyrope (Prp)-content shows an inverse pattern against Grs content.
