Re: how to calculate the effictive bulk rock composition (SM89)?

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

The strongest zoned phase seems to be amphibole, which goes from a more pargasitic composition to hornblende in the rim. I guess I am a little bit confused on the pr...
