The calculated mineral proportions are olivine:cpx garnet = 63.3 22.8 13.9 (in wt%).
The mineral proportions of such cumulates are ∼ 41% plagioclase, ∼ 39% clinopyroxene, ∼ 8% olivine and ∼ 12% Fe Ti oxides, consistent with crystallization at 2 8 kbar.
In reality, the mineral proportions do change as partial melting progresses, and Π i is the partition coefficient of element i obtained from the proportion of minerals entering the melt (Shaw 1970).
Already, more than 80% of its exports are minerals, a proportion expected to rise in a few years to 95%.
These effects have been studied in specimens made with different mixes trying to represent a wide range of mineral addition proportions.
The mineralogical characteristics that affect gold recoveries are: identities of gold-bearing minerals, identities of associated metallic and non-metallic minerals, and the proportion of gold occurring in minerals that are soluble in alkaline cyanide solutions.
If the EER originated from a melt, then the difference in Sm/Nd ratios between chondrites and the ASE should reflect the melting conditions under which the EER formed, such as the degree of melting, mineral assemblage and proportion of the residual solid, and partition coefficients.
Related to mineral composition, the proportion of Fe and Mg in olivine and pyroxene plays a central role with regard to mineral stability and the extent to which H2 may be produced.
To ease the interpretation of the different ballast Ccs we obtained, we calculated the flux of POC associated with each mineral and the proportion of total POC flux associated with each mineral.
