Abstract (in english)
   Recently, a deposital micropaleontological investigation was carried out in the area of the Mirovice metamorphic island, N of Mirovice. During geological mapping, in the orthogneisses, abundant inclusions of quartz kerotophyre of the Jílové zone have been found. The findings of orthogneiss pebbles in the Cambrian conglomerates in the Rožmitál area indicate the upper boundary of the orthogneiss body age. The existence of the so-called Jílové pressure and the origin of the pronounced cleavage is probably associated with the origin of the Central Bohemian Pluton, as it also affecteds almost all surrounding sediments. The serpentinized peridotite at Urban's mill, N of Mirovice, is underlain and overlain by Paleozoic sediments agreeing as to metamorphism and stratigraphy. The micropalentological investigation has confirmed the Silurian age, Llandovery to Wenlock, of the rocks under study. For the list and illustration of the microfossils found see Tables 1-11.
   It has been verified that the microfossils are preserved in different states of fossilization in dependence on the rock type and the metamorphism degree (Pacltová 1985-86). New minerals arisen by contact metamorphism (biotite, quartz) formed according to the predisposed shapes of the microfossils
