TL;DR: High-resolution determinations of crustal properties along the spreading center were made to gain knowledge of the source of new oceanic crust and marine magnetic anomalies, the nature of the axial magma chamber, and the depth of hydrothermal circulation.

Sherman H. Bloomer,Brian Taylor,Christopher J. MacLeod,Robert J. Stern,Patricia Fryer,James W. Hawkins,Lynn E. Johnson +6 more
TL;DR: In this paper, it was shown that the initial phases of volcanism in these subduction zones developed nearly synchronously in the middle to late Eocene over a zone up to 300 km wide and thousands of kilometers long.
Journal ArticleDOI
Evolution of intra-oceanic arc-trench systems
TL;DR: The Izu-Bonin, Mariana, Tonga, Yap and Palau trench-arc systems are examples of different stages in a dynamic process which starts when subduction begins along old fracture zone traces as mentioned in this paper.
Journal ArticleDOI
Petrology of the axial ridge of the Mariana Trough backarc spreading center
TL;DR: The axial ridge of the Mariana Trough backarc basin, between 17°40′N and 18°30′N rises as much as 1 km above the floor of a 10-15 km wide rift valley as discussed by the authors.
Journal ArticleDOI
Petrology and geochemistry of boninite series volcanic rocks from the Mariana trench
TL;DR: Boninite series volcanic rocks have been recovered from three dredge hauls on the inner slope of the Mariana Trench as discussed by the authors, including olivine boninites, boninite andesites and dacites, which are characterized by very low abundances of high-field strength cations and heavy-rare-earth elements.
