Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

A definition for ultrapotassic rocks is introduced using the chemical screens K 2 O> 3 wt.%,
MgO> 3 wt.% and K 2 O/Na 2 O> 2 for whole-rock analyses. On this basis a data base of …

Trace-element data for mid-ocean ridge basalts (MORBs) and ocean island basalts (OIB)
are used to formulate chemical systematics for oceanic basalts. The data suggest that the …

Theory of the Earth is an interdisciplinary advanced textbook on the origin, composition, and
evolution of the Earth's interior: geophysics, geochemistry, dynamics, convection …

Mid-ocean ridge basalts (MORB) are a consequence of pressure-release melting beneath
ocean ridges, and contain much information concerning melt formation, melt migration and …

Splitting or thinning of lithosphere above a mantle plume can result in voluminous melt
generation, leading to the formation of large igneous provinces, or LIPs. Examples of LIPs …

This monograph was begun with two objectives in mind. The first was to provide a review of
research involving the application of neodymium isotopic measurements to pro blems in …

This is a book about the petrology of kimberlites. It is not about upper mantle xenoliths,
diamonds, or prospecting for kimberlites. The object of the book is to provide a …

The anhydrous melting behaviour of two synthetic peridotite compositions has been studied
experimentally at temperatures ranging from near the solidus to about 200° C above the …

Back-arc basins are formed by extensional processes similar to those occurring at mid-
ocean ridges. However, whereas the magmas erupted along the major ocean ridges are …
