Stratigraphy
| Local section: | Psie Gorki | Local bed: | 8 | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 47 samples collected from thickness of about 8.5 meters surrounding Frasnian-Famennian boundary, which is placed at base of bed 8. This collection is number PG 31 from within bed 8. [JA: the Famennian part of the section extends up to the Palmatolepis crepida zone, so it is entirely early Famennian] | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal grainstone |
| Includes fossils? | Y |
| Lithology description: See geology comments. | |
| Environment: | marine indet. |
| Geology comments: Overall sequence interpreted as open marine photic zone, fore shoal (beds 1 to 4; microfacies 1 to 3) to mixed algal backshore and crinoidal foreshore (beds 5 through 11; microfacies 4). Several microfacies are also recognized: 1. burrowed bioclastic wackestones and packstones. 2. burrowed bioclastic peloidal packstones (2a. fine-gr. packstones, heavily bioturbated; 2b. coarser packstones with larger bioclasts). 3. peloidal laminated bioclastic grainstones (3a. fine grainstones with same bioclasts as microfacies 2; 3b. coarser, with cross-stratification and alternation of fine and coarse bioclastic laminae); 4. coarse grained floatstones and grainstones (4a. microconglomeratic floatstones with corals; 4b. coarse grainstone-rudstone with a few oncoids and rare micritized ooids; 4c. med.. to coarse crinoidal grainstone rich in subrounded microbreccias). This collection is 4b. | |
