LA6, Palaeoaplysina boundstones, core 7128/6-1, Orn Fm. (Permian of Norway)

Also known as Reef 3052

Where: Norway (71.5° N, 28.4° E: paleocoordinates 27.0° N, 19.2° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Orn Formation (Gipsdalen Group), Asselian (298.9 - 295.5 Ma)

• Late Asselian

• bed-level stratigraphic resolution

Environment/lithology: intrashelf or intraplatform reef; bafflestone and bindstone

• Patchy buildups growing within the inner-middle ramp areas, with normal salinity and oxygenation at the bottom. Interstitial muddy textures suggests buildups growth within low-moderate hydrodinamic settings, whereas the presence of interstitial grainstones would suggest periodic higher energy conditions.
• Bafflestone-Bindstones, with interstitial Wackestone/Packstones

Size classes: macrofossils, mesofossils

Collection methods: core
