The coral cross-sections exhibit tree ring-like concentric growth bands, prompting the selection of two growth directions for testing in samples SY067-7 and SY268-10 to examine the reproducibility of elemental distribution across different growth axes. The main line corresponds with the magnesium isotope testing path, while position represents the measurement points' distance relative to the growth central axis.110.71117.1216.5517.64
