Compatible element plots

Figure 22 Schematic plot of concentration versus distance for compatible versus incompatible elements in a mineral that is resorbed and regrown. Solid line shows final profile. Dashed line shows original profile for compatible element, prior to dissolution. If trace element zoning is radially distributed, this process would lead to an annulus and moat in compatible and incompatible elements, respectively (source Yang and Rivers, 2002).

Figure 10 Mg/Si versus Al/Si for chondritic meteorites and the Earth s mantle. Carbonaceous chondrites are on the right side of the solar ratio (fuU star), ordinary and enstatite chondrites are on the left side, reflecting depletion of refractory elements. The Earth s mantle plots above CTchondrites. Putting 5% Si into the core of the Earth leads to a PM composition compatible with CV-chondrites (after O Neill and Palme, 1998).

Figure 4.23 Trace element concentrations normalized to the composition of the primordial mantle and plotted from left to right in order of increasing compatibility in a small fraction melt of the mantle. The normalizing values are those of McDonough et aL (1992) — Table 4.7, column 4. (a) Upper and lower continental crust from Weaver and Tamey (1984) — data in Table 4.8 (b) Average N-type MORE from Saunders and Tamey (1984) and OIB from Sun (1980) -— data in Table 4.8.

Primitive mantle Brugraann et al. (1987) present a primitive mantle-normalized PGE (Pd, Ru, Os, Ir) normalization — Au - Cu - Ni plot (Figure 4.28). The elements are broadly arranged in order of increasing compatibility in the primitive mantle from left to right across the diagram. Primitive mantle values are listed In Table 4.11. Also shown are estimated values for the Archaean mantle (Sun, 1982) and the fertile mantle (Sun, et al. 1991) to illustrate the observation of Bnigmann et al, (1987) that the estimated... 

Fig. 13. EOS data for the actinides at ambient temperatures, taken from Benedict (1987 and references therein) and plotted in the form of normaUzed stress, tj, versus scaled radii, r,. It can be noted that a common curve fits, within the experimental spread, all the data for Pa, U, and Np. Furthermore, one common value, tj = —4.8(2), seems to be compatible with all the low-pressure data of Am, Cm, Bk, and Cf. Only the deviation for Bk may be significant. The individual curves (dashed lines) for the collapsed phases of these elements can be shifted to the common curve (solid lines) by the use of individual values for the extrapolated ambient-pressure volumes of these phases.
