how to calculate the effictive bulk rock composition (SM89)?
Hi everyone,
 
I am a graduate student from China University of Geoscience (Beijing). I have a question to ask you for help.
 
I fail to calculate a pseudosection in the NCKFMASHTO system with MORB composition of Sun & McDnough (1989) used in the article (Green et al., 2016, JMG,https://onlinelibrary.wiley.com/doi/pdf/10.1111/jmg.12211). could you tell me how to obtain the effictive bulk rock composition (SM89) in this article?
 
 
 
best wish

Shilin,

Here is T-D input for SM89 MORB with Fe3+/Fetotal = 10% and 10 moles of H2O:


SI(48.21)AL(16.73)CA(11.23)MG(11.69)FE(7.49)K(0.41)NA(4.81)TI(0.97)H(18.11)O(165.91)

Thanks,

Richard
