Rhodolith Pavement facies, Upper Coralline Limestone Fm. (Miocene of Malta)

Where: Malta (35.9° N, 14.4° E: paleocoordinates 35.7° N, 14.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Upper Coralline Limestone Formation, Messinian (7.2 - 5.3 Ma)

• The strata are thought to be Messinian or possibly late Tortonian in age

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; reef rocks and wackestone

• the most widespread facies, both vertically (0.4 m to 14 m) and laterally (up to 10 km). It is also within this facies that rhodoliths attain their greatest size, some having long axis dimensions in excess of 200 mm. The sediments consist of alternations of rhodoliths and wackestones as plane beds or cross beds (Fig.5C). Point counts from rhodolith beds have mean values of 49.5% rhodolith and 46% wackestone, comprising micrite and finely comminuted foraminifera, algal clasts and other debris.
• rhodolith pavement; rhodoliths and wackestones

Size classes: mesofossils, microfossils
