Our results are best matched by a basalt-enriched mantle transition zone, with higher basalt fractions near 660 (~40%) than 410 (~18–31%). ... Mapping the distribution of compositional heterogeneity is challenging, because in much of the mantle, seismic waves, our best deep Earth probes, are most sensitive to variations in temperature.

Prediction of chloride ion concentration distribution in basalt
The distribution of points on the plot reveals the direction and magnitude of the overall influence of the feature on the prediction results. The analysis shows that the BPFRC-CC is negatively correlated with the depth, basalt fibers, and polypropylene fibers, whereas age, water-cement ratio, and environment exhibit a positive correlation.
