Summary Trace-element data for mid-ocean ridge basalts (MORBs) and ocean island (OIB) are used to formulate chemical systematics oceanic basalts. The suggest that the order of trace-element incompatibility in is Cs ≈ Rb (≈ Tl) Ba(≈ W) > Th U Nb = Ta K La Ce Pb Pr Mo) Sr P Nd (> F) Zr Hf Sm Eu Sn Sb) Ti Dy (Li) Ho Y Yb. This rule works general suggests overall fractionation processes operating during magma generation evolution relatively simple, involving no significant change...
'Reduce, reuse, and recycle' urge environmentalists; in other words, do more with less order to minimize damage. But as architect William McDonough chemist Michael Braungart point out this provocative, visionary book, approach only perpetuates the one-way, 'cradle grave' manufacturing model, dating Industrial Revolution, that creates such fantastic amounts of waste pollution first place. Why not challenge belief human industry must damage natural world? In fact, why take nature itself our...
A mass imbalance exists in Earth for Nb, Ta, and possibly Ti: continental crust depleted mantle both have subchondritic Nb/Ta, Nb/La, Ti/Zr, which requires the existence of an additional reservoir with superchondritic ratios, such as refractory eclogite produced by slab melting. Trace element compositions minerals xenolithic eclogites derived from cratonic lithospheric show that rutile dominates budget Nb Ta imparts a Ti/Zr to whole rocks. About 1 6 percent weight is required solve silicate...
Eight silicate glasses were prepared by directly fusing and stirring 50‐100 g each of basalt, andesite, komatiite, peridotite, rhyolite, quartz‐diorite. These are referred to as MPI‐DING made for the purpose providing reference materials geochemical, in‐situ microanalytical work. Results from various analytical techniques indicate that individual glass fragments well homogenised with respect major trace elements at μm mm scale. Heterogeneities due quench crystallisation olivine have been...
