Stratigraphy
Lithology and environment
| Primary lithology: | shelly/skeletal "limestone" |
| Secondary lithology: | shelly/skeletal "limestone" |
| Includes fossils? | Y |
| Environment: | open shallow subtidal |
| Geology comments: Two lithofacies can be distinguished. The lower part is composed of biostrome with abundant crinoid ossicles, lamellar stromatoporids and tabulate auloporids. The biostrome is overlain by hard, partly dolomitized pink crystalline limestone, with crinoid ossicles, geodes, and ochre in the fissures. | |
