Figure F24. A. Comparison of mean of major and minor element abundances in the suite of Atlantis II basalts analyzed by Johnson and Dick (1992) and the mean major and minor element abundances of Hole 1105A plutonic samples. The best fit line closely follows the 1:1 line, suggesting a one to one relationship between the mean major and minor element compositions of both volcanics and plutonics. B. Comparison of the mean abundance of rare earth elements (REEs) in Atlantis II basalts and 148 Hole 1105A plutonic samples. The observed trend is close to the 1:2 line, suggesting that mean REE concentrations in Hole 1105A plutonics is almost half of that present in the mean of volcanics. All samples including granophyres were used in computing means.
