Fibrous microquartz replacing the bioclasts belongs always to quartzine and lutecite, while fibrous chalcedony (length-fast chalcedony) was found only as the filling of sponge spicules. Silicification displaying the orbicule structure („beekite”) occurred exclusively in the Liassic limestones and was limited to oyster shells and belemnites. A file of susceptibility to the silicification of calcite skeletons of the various organisms was derived. The frequency of dispersed silicification within the shallow-water limestones of the Upper Jurassic and Barremian-Aptian proceeding from various tectonic units was compared and utilised for source analyses of pebbles in conglomerates. The zones of recrystallized shell first described by Maliva & Siever (1988) were confirmed by our study.
