Yeah, that would do it!

So, where and how has it since been re-sequestered? Hard to imagine subduction as an adequate mechanism for all of it.

the number of hypotheses about the PT crisis fast approaches the number of workers on the problem.

The article itself is paywalled?

I like interdisciplinary research and something on both element cycling during subduction and the PT event is kinda interesting to me

Do the authors pose storage in the subcontinental lithospheric mantle?
