Abstract (in english)
   A new lithotype of peridotite, phlogopite- and apatite-bearing spinel-garnet peridotite, associated with leucocratic granulite, has been recognized at the Plešovice quarry in the Gföhl Unit within the Moldanubian Zone of the Bohemian Massif, Czech Republic. There are three equilibrium stages in the Pleovice peridotite. The existence of Stage I, the precursor spinel ? garnet peridotite stage, is supported by the presence of an aluminous (Al2O3 ~3,0 wt %) orthopyroxene megacryst in the matrix. The minimum temperature of Stage I was estimated to be 1020 ? 15°C.
