Lithology and environment
Primary lithology: | lithified "reef rocks" |
Lithology description: Reef mounds on lower to middle ramp position. Data from several facies: oncoid-peloid wacke-floatstone, bioclastic wackestone, lump packstone, bioclastic grainstone, algal bindstone, breccia, grapestone, silty wackestone. | |

Collection methods and comments
Collection methods: | selective quarrying,peel or thin section,field collection |
Reason for describing collection: | biostratigraphic analysis |
Collection method comments: Data only occasionally separated fro different outcrops and formations. Thus compiled for whole region and two reefal formations |
