The role of the subducting lithospheric slab in the genesis of mantle-derived (primitive) magmas is investigated through a study of volcanic rocks formed in the tectonically strike-slip–dominated…
Along‐Strike Variation in the Aleutian Island Arc: Genesis of High Mg# Andesite and Implications for Continental Crust

Based on a compilation of whole rock geochemistry for approximately 1100 lava samples and 200 plutonic rock samples from the Aleutian island arc, we characterize along-strike variation, including…
The Role of Water in Generating the Calc-alkaline Trend: New Volatile Data for Aleutian Magmas and a New Tholeiitic Index
The origin of tholeiitic (TH) versus calc-alkaline (CA) magmatic trends has long been debated. Part of the problem stems from the lack of a quantitative measure for the way in which a magma evolves.…
Geochemical evidence for the melting of subducting oceanic lithosphere at plate edges

Geochemical data from the Kamchatka peninsula and the Aleutian islands are presented that reaffirms the slab-melt interpretation of adakites, but in the tectonic context of the exposure to mantle flow around the edge of a torn subducting plate.

Author(s): Bryant, J.A.; Yogodzinski, G.M.; Hall, M.L.; Lewicki, J.L.; Bailey, D.G. | Abstract: Whole-rock geochemical data on basaltic to rhyolitic samples from 12 late Pleistocene-Holocene centers…
A record of spontaneous subduction initiation in the Izu–Bonin–Mariana arc

- 1 September 2015
The initiation of tectonic plate subduction into the mantle is poorly understood. If subduction is induced by the push of a distant mid-ocean ridge or subducted slab pull, we expect compression and…
