In the Hogklint Beds of the Vattenfallet and Nygérdsbecken sections sediments of restricted and open shelf and shoal environments are exposed.According to the chitinozoan data, not any of the boundaries between the subunits of the Hogklint Beds corresponds exactly to the distinct boundary between the Mustjala and Ninase members in the sections of Saaremaa.In the lowermost part of the Slitebrottet 2 quarry open shelf nodular limestones with a few sharp hardgrounds, marking boundaries of field-scale (meso)cycles, are present.The succession of chitinozoan species indicates that the studied section of Slitebrottet 2 corresponds to the upper part of the Cingulochitina cingulata Biozone and the lower part of the Eisenackitina lagena Biozone in the lower half of the Jamaja Formation in the Ohesaare section of Saaremaa.
