Geochemical characteristics of basaltic volcanism within back-arc basins

AD Saunders, J Tarney - Geological Society, London, Special …, 1984 - lyellcollection.org
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 …

[KNYGA][B] Orogenic andesites and plate tectonics

JB Gill - 2012 - books.google.com
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 …

Chromian spinel as a petrogenetic indicator in abyssal and alpine-type peridotites and spatially associated lavas

HJB Dick, T Bullen - Contributions to mineralogy and petrology, 1984 - Springer
The composition of chromian spinel in alpine-type peridotites has a large reciprocal range of
Cr and Al, with increasing Cr#(Cr/(Cr+ Al)) reflecting increasing degrees of partial melting in …

[KNYGA][B] Pyroclastic rocks and tectonic environment

RV Fisher, HU Schmincke, RV Fisher, HU Schmincke - 1984 - Springer
The close proximity of continental borderlands, active and ancient tectonic regions, and
modern and ancient volcanoes has long been known. Pre-plate tectonic ideas about this …

Origin and history of the South China Sea basin

B Taylor, DE Hayes - Geophysical Monograph Series, 1983 - ui.adsabs.harvard.edu
Magnetic anomaly data acquired on R/V Vema cruises in the South China Sea in 1979 have

Water in Earth's mantle: the role of nominally anhydrous minerals

DR Bell, GR Rossman - Science, 1992 - science.org
Most minerals of Earth's upper mantle contain small amounts of hydrogen, structurally bound
as hydroxyl (OH). The OH concentration in each mineral species is variable, in some cases …

JA Pearce, RJ Stern - Back‐arc spreading systems: Geological …, 2006 - researchgate.net
The compositions of back-arc basin basalts (BABB) can usefully be viewed as products of
four factors:(1) the composition of inflowing mantle and its preconditioning during flow to the …

The role of water in the petrogenesis of Mariana trough magmas

E Stolper, S Newman - Earth and Planetary Science Letters, 1994 - Elsevier
Most variations in composition among primitive basalts from the Mariana back-arc trough
can be explained by melting mixtures of an NMORB-type mantle source and an H 2 O-rich …
