REE Spider Plot

 

Figure 1:  Spider plot highlighting different PAAS-normalized
REE patterns representing natural environments and minerals that display the anomalous features of REE.  Seawater patterns are typically universal while other patterns (like pore waters) tend to vary on a local scale (Tostevin et al., 2016).

  1. Hi Matt, you gave a great explanation of this plot. It is a lot to take in and I think you broke it down into smaller parts really well. While the pattern of each reservoir is different, I think it would be good to offer a bit more explanation to the y-axis, as each reservoir is on several different orders of magnitude some description as to why some reservoirs are much higher than others could have been helpful. Great talk!
