摘要Isotopic compositions of boron (delta B-11(c) value) and elemental concentrations of B, Ca, Mg, Fe and Al in growing corals from Sanya Bay, China and Kavaratti Lagoon, India along with delta B-11(sw) values and pH values of the coexisting sea water have been measured in this study using TIMS. The delta B-11(c) values of growing corals behave inconsistently and are not related to the concentrations of Fe and Al in corals. The higher delta B-11(c) values of corals imply additional amount of trigonal species of boron to be incorporated into corals. Based on the measured delta B-11 values of growing corals and coexisting sea water as well as the pH of co-existing sea water, a new isotopic fractionation factor alpha(43) between two boron species, B(OH)(4)(-) and B(OH)(3), has been measured to be 0.980, consistent with the well accepted alpha(43) of 0.981 established by earlier workers.
