Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

This textbook is a complete rewrite, and expansion of Hugh Rollinson's highly successful
1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and …

The origin of enriched mantle (EM) sources remains an unsolved problem for constraining
the composition and chemical evolution of the Earth's mantle, because a wealth of different …

Geochemical and isotopic data suggest that the source regions of oceanic basalts may
contain pyroxenite in addition to peridotite. In order to incorporate the wide range of …

It is now well established that lithospheric thinning of the eastern North China Craton (NCC)
occurred during the Phanerozoic. The cause and extent of the thinning, however, remains …

Mineralogical variations in the Earth's mantle and the relative proportions of peridotitic
versus enriched and potentially crustally-derived pyroxenitic domains within the mantle have …

Isotope systematics of basalts provide information on the distribution of mantle components
and the length scale of mantle heterogeneity. To obtain this information, high data and …

In order to better constrain the Mg isotopic composition of the mantle, we have analysed
twenty-eight samples of both oceanic and continental peridotite using a high-precision …

The isotopic composition of radiogenic systems is a powerful tool to investigate Earth's
evolution through time. Most of our understanding of the processes that affect the isotopic …
