Basalts 55 Cs 0.1125           µg/g Rock samples taken from DSDP Hole 418A, which in this particular case is taken to represent all oceanic crust. The fact that Hole 418A was drilled to 550m made it a prime candidate since at the time it was one of the deepest holes drilled. Along with its depth, Hole 418A has also been measured for K, Rb and Cs by other sources and found to have no active alteration processes. Hart & Staudigel 1982

Extrusive Section Oceanic Crust 55 Cs 0.0131           µg/g Average compositions of DSDP Leg 34 Basalts to compare with other Upper Crust alkali fluxes from other sites and sources given in Hart & Staudigel 1982. The ultimate goal in comparing and contrasting these alkali fluxes is to find whether Oceanic Crustal alteration processes are relevant sinks for alkalies input into the ocean by riverine processes. Hart & Staudigel 1982 Hart 1976
