A variety of carbonate buildups developed in the Lusitanian Basin during the late Jurassic. During an Oxfordian–Kimmeridgian rift phase evidence can be seen for both fault and diapiric control of buildup development. Fault-controlled buildups occur on the east side of the basin. They exhibit shelf profiles, are relatively thin (200–500 m), show well-developed lateral facies zonation and are dominated by lime mudstones and wackestones, with only minor amounts of packstones and grainstones. Salt-controlled buildups on the northwest margin of the basin are relatively thick (500–1500 m), show only gradual lateral facies variation with no distinct shelf break facies, and are dominated by grainstones and packstones.

During the latest Oxfordian–early Kimmeridgian, a sudden relative sea-level rise drowned or partially drowned the earlier buildups, and this was quickly followed by a major influx of siliciclastic sediments. In the centre of the basin, a thin grainstone-dominated carbonate sequence of middle Kimmeridgian age developed on top of a prograding siliciclastic slope system. In the siliciclastic-starved southern part of the basin, a prograding low-energy ramp sequence of Kimmeridgian–Berriasian age was deposited.

Carbonate facies associations described from Portugal also occur in Mesozoic carbonate bank sequences of eastern America. Data from recent US wells, and comparisons with Portugal, suggest that the eastern American Atlantic ‘reef trend’ is largely composed of grainstone–packstone dominated shelf-break sediments with only relatively minor amounts of biogenic reefal framework.
