The Roles of Lherzolite and Garnet Pyroxenite
Textural, major element and trace element data for xeno-liths from Salt Lake Crater, Hawaii indicate that typical four phase lherzolite inclusions (olivine, orthopyroxene, chrome diopside and spinel) found worldwide in basalts are not samples of primitive upper mantle. Rather, lherzolite may be the recrystallized residue left after a basaltic melt extracts the easily fused components from pre-e...
متن کاملSheared lherzolite xenoliths revisited
[1] The microstructures of sheared lherzolite xenoliths from South African kimberlites are investigated using new microstructural analysis techniques and new rheological data. By applying electron backscatter diffraction (EBSD) methods and the M-index technique for quantifying the strength of lattice preferred orientation (LPO), it is demonstrated that olivine and orthopyroxene, after an initia...
متن کاملSamarium-neodymium systematics in kimberlites and in the minerals of garnet lherzolite inclusions.
The initial ratios of neodymium-143 to neodymium-144 in kimberlites ranging in age between 90 x 10(6) to 1300 x 10(6) years from South Africa, India, and the United States are different from the corresponding ratios in the minerals of peridotite inclusions in the kimberlites but are identical to the ratios in the basaltic achondrite Juvinas at the times of emplacement of the respective kimberli...
متن کاملToward Developing a Garnet Lherzolite Saturation Model for Lunar Low-ti, Ultramafic Green Glass Compositions
Introduction: The petrogenesis of the low-Ti lunar ultramafic glasses is critical to the understanding of volcanic processes on the Moon. Popular petrologic models developed to explain the formation of these glasses involve high pressure melting of a variety of sources, including primordial, garnet bearing, lunar mantle and depleted lunar magma ocean (LMO) cumu-lates [1,2,3,4]. Following the hi...
متن کاملMelting Behaviour of Model Lherzolite in the System CaO–MgO–Al2O3–SiO2–FeO at 0·7–2·8 GPa
Fe–Mg exchange is the most important solid solution involved in for Fe–Mg exchange between the coexisting crystalline phases and melt, KdFe–Mg, show a relatively simple and predictable behaviour partial melting of spinel lherzolite, and the system CaO– MgO–Al2O3–SiO2–FeO (CMASF) is ideally suited to explore with pressure and temperature: the coefficients for olivine and spinel do not show signi...
