Notes: Data are self consistent, whereby CO2 + CaO = CaCO3, see "Hard Rock Sampling and Geochemical Analyses" in "Geochemistry" in the "Explanatory Notes" chapter. * = (Al/[Al]PAAS) x 100. † = SiO2 - (3 x Al2O3). ‡ = Fe/Al. BDL = below detection limit. Use caution if using absolute values. Only a portion of this table appears here. The complete table is also available in ASCII.
