Two reefal bands:
1. Limestones, dolomitized, massive, archaeeocyathit-algal, white, gray or cherry-red, and also limestone breccias and bioherms with archaeocyathids, which are evenly distributed through the band.

2. Tuffs, tuffites, and more rarely dacite porphyries of dirty-brown, gray or greenish-gray color, with lenses of algal and archaeocyathid-algal-limestones, massive and dolomitized.
