and the Urgonian Formation in France have been compared to the Resolution Guyot carbonates. All these platforms were located in Tethyan seas and several formations in these three carbonate environments are correlated; for example, the fauna identified on Resolution Guyot resembles that from other Northern Hemisphere platforms. Analogies also exist to platforms in Venezuela. Water temperatures in the early Aptian (ca. 125 – ca. 113 million years ago) are inferred to have been . The platform was exposed to southeasterly trade winds which left its northern side sheltered from waves, except from storm-generated ones. These waves, wind and tidal currents acted to shift sediments around on the platform. Storms formed beaches on the platform, although the interior parts of the platform were effectively protected by the surrounding shoals from storm influence. Some patterns in the sedimentation indicate a seasonal climate. When the climate was arid, gypsum deposition took place. Through the history of the platform sea level variations led to changes in the accumulating carbonate sediments, with typical facies and sequences forming in the carbonate layers. The Selli event, an oceanic anoxic event, is recorded at Resolution Guyot as is the Faraoni event. The Selli event left a black shale layer and may have caused a temporary interruption in carbonate accumulation before the platform recovered. During the Albian-Aptian some carbonates became dolomites. Life on Resolution Guyot included algae – both green and red algae and species forming microbial mats –, bivalves including rudists, bryozoans, corals, echinoderms, echinoids, foraminifera, gastropods, ostracods, oysters, serpulid worms, sponges and stromatoliths. Fossils of animals have been found in the drill cores. Rudists and sponges have been identified as bioherm builders; rudist families found on Resolution include Caprinidae of the genus Caprina, Coalcomaninae, Monopleuridae and Requieniidae. Well developed microbial mats grew in some places. Plant remnants have been found in the carbonate sediments, probably reflecting the existence of vegetation-covered islands on the platform. Vegetation probably occurred in swamps and marshes as well. Uplift and karstification During the Albian to Turonian (93.9 – 89.8 ± 0.3 million years ago), the carbonate platform rose above the sea by about –. This uplift episode at Resolution Guyot is part of an episode of more general tectonic changes in the Pacific Ocean, with a general uplift of the ocean floor and tectonic stress changes at the ocean margins. This tectonic event has been explained by a major change in mantle
