영문 초록

Equations of the linear relationship including zero age depths between the basement depth and the square root of age for 6 active back-arc basins, were obtained from the statistical analysis of a great number of underway bathymetric profiles. Active back-arc basins show a large variety of zero age depths ranging from the shallowest Manus Basin to the deepest Mariana Trough. Variations in zero age depth appear to show good correlations with the dipping angle of slab, convergence rate, spreading rate, and cooling coefficient. The dipping angle of subducting slab increases with the increase of the zero age depth. As the convergence rate decreases, the zero age depth also becomes deeper. The variation in zero age depth of active back-arc basin seems to be caused by the mechanical supporting of the subduction slab. Zero age depths are deeper with the decrease of spreading rates and cooling coefficients.
