The Lesser Antilles volcanic arc is related to subduction of the American plate under the
Caribbean plate. The rate of subduction is low, 2–4 cm a− 1, and this has been reflected, at …

This paper attempts to review those salic eruptives in which Si0 2> 60%, but specifically
excluding peralkaline and silica-undersaturated types. The approach is based on a …

Students of a phenomenon as common but complex as andesite genesis often are
overwhelmed by, or overlook, the volume and diversity of relevant information. Thus there is …

Abstract Analytical data for Sr, Rb, Cs, Ba, Pb, rare earth elements, Y, Th, U, Zr, Hf, Sn, Nb,
Mo, Ni, Co, V, Cr, Sc, Cu and major elements are reported for eocene volcanic rocks …

A map of the ocean basins (Fig. 5.1) shows that their most conspicuous topographic feature
is the system of mid-oceanic ridges, the crests of which rise on average 1000-3000 m above …

Abstract Analyses for Ti, Zr, Y, Nb and Sr in over 200 basaltic rocks from different tectonic
settings have been used to construct diagrams in which these settings can usually be …

Use of some petrologic diagrams applied to analyses of volcanic rocks is unnecessarily
difficult due to lack of data for construction of discriminant lines between rock series …

Utilization of scientific terms in geology has several inherent problems, particularly when
contemplating both process and description. Ophiolite has had a particularly notorious …

This substantially revised edition includes recently published information relating to plate
tectonics and continental origin. A large number of new figures have been added, and new …

Five minor and trace elements have been variously combined to produce a set of binary
diagrams in addition to total alkali-SiO 2 diagrams, that discriminate between fresh tholeiitic …
