• who: Shlomy Vainer from the Amalgamated sand samples of ~, gr were sieved in the lab and quartz was separated and purified from the, u03bcm fraction to determine in-situ Al and Be concentrations (Supplementary Data, ) The procedure involved sample leaching by aqua regia solution (3:, of HCl:HNO3) at , u00b0C, magnetic separation, and sequential HF + , etching. Be and Al spikes at known isotopic ratios were added prior to quartz digestion in HF, HClO4, and , mixture. Aliquots were extracted from the dissolved fraction for native Al measurements by ICP-MS at the Hebrew University of Jerusalem. Al+, and . . .
