Due to their large heat and moisture storage capabilities, the tropics are fundamental in modulating both regional and global climate. Furthermore, their thermal response during past extreme warming periods, such as super interglacials, is not fully resolved. In this regard, we present high-resolution (analytical) foraminiferal geochemical (δ18O and Mg/Ca) records for the last 1800 kyr from...

Carbonate mounds of the Moroccan Mediterranean margin: Facies and environmental controls

Terhzaz, Loubna ; Hamoumi, Naima ; Spezzaferri, Silvia ; El Lotfi, Mostapha ; Henriet, Jean-Pierre

In: Comptes Rendus Geoscience, 2018, vol. 350, no. 5, p. 212–221

Sedimentological and geochemical studies of boxcores from the Brittlestar Ridge I and Cabliers carbonate mounds, along the Moroccan Mediterranean margin, show that sediments are composed of cold water scleratian corals and micritic mud, muddy micrite or muddy allochem limestone matrix, outlining seven different facies that can be attributed to “cluster reefs”. The mixed...
