Lithology and environment
| Primary lithology: | gray lithified lime mudstone |
| Lithology description: consists predominantly of grey to pale-grey calcarenitic limestones...during asbian times, a micritic apron-reef facies formed extensive fringing mudbanks on the flanks of this platform [a shallow marine shelf or platform limestone]. | |
| Environment: | reef, buildup or bioherm |
