Lithology and environment
| Primary lithology: | bioturbation,nodular,gray,blue grainstone |
| Includes fossils? | Y |
| Lithology description: The exposed Areia do Mastro Formation beds mainly consist of bluish-grey clay-limestones dominated by micrite, 0.5–2.1 m thick, intercalated with sandy (quartz-rich) micritic limestone beds, 0.3–0.6 m thick. Most of the beds show a nodular texture due to intense invertebrate bioturbation (mainly Thalassinoides suevicus), typical of an intertidal to subtidal lagoon environment...The bed AM7 (Fig. 2) also contains internal moulds of gastropods and rare fragments of turtle shell." | |
| Environment: | lagoonal/restricted shallow subtidal |
| Geology comments: "a carbonate subtidal to intertidal lagoon environment" | |
