XRF results of B4 sediments. Depth profiles of Zirconium (Zr), Sodium oxide (Na2O), Potassium oxide (K2O), Hafnium (Hf), Niobium (Nb), Zirconium/Rubidium (Zi/Rb), Zirconium/Silica oxide (Zr/SiO2), Zirconium/Titanium oxide (Zr/TiO2) and of the chemical proxy of alteration (CPA = Al2O3/(Al2O3 + Na2O), inversed scale. The light orange color shows dryer events while orange color indicate desiccation layers developed during Heinrich Event 1(H1) and the hiatus. Blue color indicates the African Humid Period (AHP) and other humid episodes while dark green color indicates the event characterized as humid and arid according to pollen and geochemical results, respectively
