His name originates fromwebsterite, an igneous rock. Tattle[edit] "That's Websterite... He's a Cragnon who likes anything new and trending. The lives of Cragnons recently changed dramatically... Like Websterite, many are enjoying lives of convenience now..." ...
Whole rock major and trace element abundances in aluminous garnet–spinel websterite, sapphirine-bearing Mg–Al granulite and hibonite-bearing Ca–Al granulite xenoliths from the Chyulu Hills volcanic field, Kenya, suggest that the samples represent a meta-igneous suite linked by fractionation. The...

Instead, the calculated composition of the liquid in equilibrium with the websterite's most magnesian minerals and the bulk-rock composition are more akin to those of a poorly differentiated T-MORB than of N-MORB parental magma. Phase relations and mineral compositions produced by anhydrous melting...
The wall rock depletion of the first transition type is interpreted as caused by melt extraction induced by intrusion of melts derived from deeper mantle (garnet-facies), whereas the LREE and Sr variation is interpreted in terms of diffusive redistribution of trace elements after emplacement of the...
These two rock types share at least one stage of their history. This is in particular highlighted by the major and trace element compositions of their clinopyroxenes but also by the continuum of composition observed for olivine, orthopyroxene and spinel. Indeed the clinopyroxene major element ...

Melt/rock reactionTextural evolutionSpinel peridotite and associated olivine websterite form an ultramafic massif at the base of the Purang ophiolite complex of western Tibet. The spinel peridotites consist chiefly of harzburgites with lesser amounts of lherzolite and dunite. All of the peridotites ...
