摘要: The Agadir Basin is a mixed siliciclastic-volcaniclastic deepwater turbidite system derived from several sedimentary sources. Estimating the influence of these sources requires detailed geochemical profiles sediment cores. This achieved using an ITRAX µXRF core scanner that normally produces elemental in units counts or count rate. Improved insights are if data calibrated to produce concentration data. Turbidite geochemistry can then be used more reliably infer flows and identify primary sources, which Moroccan slope for siliciclastic beds western Canary Islands volcaniclastic turbidites. Cross-plots discriminate variations between different beds. For example, differences two distinctive marker beds, named A2 A14, reflect their respective Island indicate primitive basaltic source bed evolved A14. Compositional deposits potential failed location failure on continental slope.
