SUMMARY

Petrographic examination of some Werfenian limestones of the Dolomite region in northeastern Italy has revealed these iimestones to show an unusual granular texture. This texture seems to have originated during an early resedimentation attempt when the sediments in which they occur were still water impregnated. Because these “pseudo-grains” never existed as free clastic entities but yet recall intraclastic grains they are defined as protointruclusts and the rock as protointruclastic micrite.
