Abstract. The Aptian–Albian interval is characterized by significant paleoclimatic, paleoceanographic, and paleogeographic changes, which in turn affected the distribution evolution of marine ecosystems. Despite importance such studies, there have been few correlations between sections Tethys Sea those South Atlantic Ocean. This interval, including transition, preserved deposits Riachuelo Formation (Sergipe–Alagoas Basin, Brazil) located Ocean; therefore, this location was chosen for...
SUMMARY During the Jurassic and Early Cretaceous, Earth's magnetic field experienced a high frequency of polarity reversals. This hyperactivity period is followed by ∼38 Myr prolonged stable normal from Aptian until Santonian, known as Cretaceous Normal Superchron (CNS; chron C34n, 121.4 to 83.65 Ma). However, CNS might have been characterized more variability than previously thought, but current database uneven in its spatial temporal distribution. In this study, we integrate paleomagnetic...
<p>The Early Cretaceous was dominated by greenhouse conditions and increases in ocean crust production rate, with critical climate, geography oceanography changes abrupt shifts redox the oceans. Prior to Aptian, regarding Earth’s magnetic field, a high rate of polarity reversals dominated. However, thereafter, period stability, known as Normal Polarity Superchron (CNPS), established for 34 Myr. Although, there are debates on causes consequences these extreme...
