Abstract

Name: Urgonian carbonate platform, Subalpine Chains

Authors: Dave Hunt and Maurice E. Tucker

Location: From 44° 80' to 46° 20' north latitude and 5° to 6° east longitude, southeastern France

Geologic time interval: Early Cretaceous, latest Hauterivian-Aptian

Tectonic-sedimentary setting: Opening ocean, passive margin

Basin type: Passive margin

Paleoclimate: Semi-arid with humid intervals

Platform type: Carbonate shelf, at times rimmed shelf

Platform geometry: 100–300 m thick; 150 km wide and 300 km long

Facies and fossils: Shelf margin bioclastic-oolitic grainstone, on-shelf rudist wackestone–packstone, foreslope grainstone–wackestone, basinal wackestone-mudstone-hemipelagite. Rudists, other molluscs, foraminifera, corals, bryozoans, calcareous algae.

Systems tracts: Lacustrine–tidal flat, open to restricted shelf–lagoonal, shelf margin, foreslope, basin
