From bottom to top, the average total rare earths of the JL125-S17 core decreases because the hydrothermal components are more concentrated in the upper part of the core
From the bottom up, the average amount of rare earths in the JL125-S17 core decreased because the thermal fluid groups were more intensive at the top of the core.
From bottom to top, the average total REE content of jl125-s17 core decreases because the hydrothermal components are more enriched in the upper part of the core<br>
