A Metastable Aluminosilica Compound for Aluminum and Water Transport to the Upper Mantle by Frans J. M. Rietmeijer, Joseph A. Nuth

“…If so, metastable phases play a role in subduction zones and it then follows that the processes and resulting conditions in these environments can be nonuniform and discontinuous at least at micrometer scales.…”

Mélange dehydration and melting beneath South Sandwich Islands arc by Yunchao Shu, Sune G. Nielsen, Veronique Le Roux, Danielle Santiago Ramos, Jerzy Blusztajn, Maureen Auro, Phil T. Leat, Tristan J. Horner

“…While a comparison of barium isotope data from four additional arcs indicates mantle wedge metasomatism remains visible in several cases, mélange mobilization is consistent with available data across all of these subduction zones.…”

Whole-rock geochemistry and crystal chemistry of apatite at intrusive suites of the Qeynarjeh-Angouran district (west of Zanjan): an approach to the identification of skarn-causati... by Afsoon Dastour, Ebrahim Tale Fazel, Ashraf Torkian

“…These intrusive suites with zircon saturation temperature (TZr) less than 900 °C and meta-aluminous to slightly peraluminous nature (A/CNK = 0.5-1.2) belong to the calc-alkaline series, which is evidence of I-type granitoids (Na2O/K2O = 0.8-2.0) in subduction zones (enrichment of LILE compared to HFSE along with P, Nb and Ti anomalies). …”

Coseismic Deformation Responses due to Geometrical Structure and Heterogeneity of the Accretionary Wedge: Study Case 2010 Mentawai Earthquake, West Sumatra, Indonesia by Alvina K. Kuncoro, Wahyu Srigutomo, Umar Fauzi

“…The 2010 tsunami earthquake was located at the Mentawai segment, which is a part of the accretionary wedge in the Sumatra subduction zone. This active accretionary wedge is identified as the most complicated structure on earth and lies along the Sumatra subduction zone, at which most destructive earthquakes happen in this region. …”

Petrology of Oligocene Lalehzar igneous rocks in the southeast of Saveh-Naein-Jiroft magmatic belt by Fatemeh Sepidbar, Bahareh Borouzi Niyat

“…The geochemistry and isotopic results show that they are formed during partial melting of the lower crust (amphibolite) which is impelemented by inherited mantle source components in a subduction zone. Introduction The magmatism at the convergent margins changes in response to processes related to the subduction zone. …”
