“…The tephra record starts in the Oligocene (33–24 Ma) and comprises 18 dacitic to rhyolitic ash beds that can be tentatively correlated with the compositional signals of Chichijima volcanism on the Bonin Ridge (Figures , and ). These ash beds differ compositionally from the Neogene and Pleistocene Izu‐Bonin ash layers as they represent a transitional composition between the typical Izu‐Bonin island arc signature and that of the more continentally influenced Japan arc (Figure ), similar to the compositions found at the Kyushu‐Palau‐arc (e.g., Brandl et al, ). Since boninitic, tholeiitic, and calc‐alkaline volcanism at the Bonin Ridge encompasses an age interval of ∼48 to ∼42 Ma (Ishizuka et al, ), the Oligocene marine tephras in the Expedition 352 sediments that were recovered close to the Bonin Ridge are likely to represent highly evolved late‐stage Kyushu‐Palau‐arc volcanism in this area that has not previously recognized.…”

Provenance studies of widely distributed tephras, integrated within a well‐defined temporal framework, are important to deduce systematic changes in the source, scale, distribution, and changes in regional explosive volcanism. Here, we establish a robust tephrochronostratigraphy for a total of 157 marine tephra layers collected during IODP Expedition 352. We infer at least three major phases of highly explosive volcanism during Oligocene to Pleistocene time. Provenance analysis based on glass composition assigns 56 of the tephras to a Japan source, including correlations with 12 major and widespread tephra layers resulting from individual eruptions in Kyushu, Central Japan, and North Japan between 115 ka and 3.5 Ma. The remaining 101 tephras are assigned to four source regions along the Izu‐Bonin arc. One, exclusively assigned to the Oligocene age, is proximal to the Bonin Ridge islands; two reflect eruptions within the volcanic front and back‐arc of the central Izu‐Bonin arc, and a fourth region corresponds to the Northern Izu‐Bonin arc source. First‐order volume estimates imply eruptive magnitudes ranging from 6.3 to 7.6 for Japan‐related eruptions and between 5.5 and 6.5 for IBM eruptions. Our results suggest tephras between 30 and 22 Ma reflect a subtly different Izu‐Bonin chemical signature compared to the recent arc. After a ∼9 Ma gap in eruption, tephra supply from the Izu‐Bonin arc predominated from 15 to 5 Ma, and finally a subequal mixture of tephra sources from the (palaeo)Honshu and Izu‐Bonin arcs occured within the last ∼5 Ma.

“…It resulted from ~52 Ma of subduction of the Pacific Plate beneath the eastern margin of the Philippine Sea plate (Reagan et al, ). IODP expedition results were published recently, notably concerning the magmatic evolution (Brandl et al, ; Yogodzinski et al, ; Hickey‐Vargas et al, ; Shervais et al, ), and the age of IBM volcanic rocks (Barth et al, ; Ishizuka et al, ; Reagan et al, ). In addition, the drilled cores provided (hemi)pelagic sedimentary‐volcaniclastic successions and tectonic structures that bear information on the tectonic evolution of the outer IBM forearc.…”

International Ocean Discovery Program Expedition 352 recovered sedimentary-volcaniclastic successions and extensional structures (faults and extensional veins) that allow the reconstruction of the Izu-Bonin forearc tectonic evolution using a combination of shipboard core data, seismic reflection images, and calcite vein microstructure analysis. The oldest recorded biostratigraphic ages within fault-bounded sedimentary basins (Late Eocene to Early Oligocene) imply a~15 Ma hiatus between the formation of the igneous basement (52 to 50 Ma) and the onset of sedimentation. At the upslope sites (U1439 and U1442) extension led to the formation of asymmetric basins reflecting regional stretch of~16-19% at strain rates of~1.58 × 10 −16 to 4.62 × 10 −16 s −1 . Downslope Site U1440 (closer to the trench) is characterized by a symmetric graben bounded by conjugate normal faults reflecting regional stretch of~55% at strain rates of 4.40 × 10 −16 to 1.43 × 10 −15 s −1 . Mean differential stresses are in the range of~70-90 MPa. We infer that upper plate extension was triggered by incipient Pacific Plate rollback 15 Ma after subduction initiation. Extension was accommodated by normal faulting with syntectonic sedimentation during Late Eocene to Early Oligocene times. Backarc extension was assisted by magmatism with related Shikoku and Parece-Vela Basin spreading at~25 Ma, so that parts of the arc and rear arc, and the West Philippine backarc Basin were dismembered from the forearc. This was followed by slow-rift to postrift sedimentation during the transition from forearc to arc rifting to spreading within the Shikoku-Parece-Vela Basin system. Plain Language SummaryThis study examines the stress and deformation conditions and timing of extension in the Izu-Bonin forearc subsequent to subduction initiation by combining seismic images and microstructure analyses on veins and fault zones. By that we also examine a hiatus of 15 Ma between the formation of igneous forearc crust and the formation of sediment basins by forearc extension. This is implemented into an overall tectonic model at lithospheric scale.

“…This started at about 44 Ma (e.g. on Chichijima, Hahajima and Saipan) (Ishizuka et al 2006;Reagan et al 2008), as also documented during Expedition 351 (Brandl et al 2017). From 42 to 25 Ma, the front of the active magmatism was located 20 km east of the present arc (Taylor and Fujioka et al 1992;Ishizuka et al 2006).…”

“…Widespread FAB volcanism also took place within the Amami Sankaku Basin, c. 250 km to the west of the Expedition 352 sites (pre-Shikoku Basin opening), as drilled at Site U1438 during IODP Expedition 351 (Arculus et al 2015c). A late Palaeocene-early Eocene age for this volcanism is possible based on radiolarians and other evidence (Arculus et al 2015c;Ishizuka et al 2016;Brandl et al 2017). The 52-48-Ma age range of volcanic rocks recovered from the Bonin forearc (Ishizuka et al 2011a;Reagan et al 2017) is comparable to the basaltic basement of the Amami Sankaku Basin drilled at Site U1438 (Arculus et al 2015c(Arculus et al , 2015a(Arculus et al , 2015bReagan et al 2017).…”

New biostratigraphical, geochemical, and magnetic evidence is synthesized with IODP Expedition 352 shipboard results to understand the sedimentary and tectono-magmatic development of the Izu-Bonin outer forearc region. The oceanic basement of the Izu-Bonin forearc was created by supra-subduction zone seafloor spreading during early Eocene (c. 50-51 Ma). Seafloor spreading created an irregular seafloor topography on which talus locally accumulated. Oxide-rich sediments accumulated above the igneous basement by mixing of hydrothermal and pelagic sediment. Basaltic volcanism was followed by a hiatus of up to 15 million years as a result of topographic isolation or sediment bypassing. Variably tuffaceous deep-sea sediments were deposited during Oligocene to early Miocene and from mid-Miocene to Pleistocene. The sediments ponded into extensional fault-controlled basins, whereas condensed sediments accumulated on a local basement high. Oligocene nannofossil ooze accumulated together with felsic tuff that was mainly derived from the nearby Izu-Bonin arc. Accumulation of radiolarian-bearing mud, silty clay, and hydrogenous metal oxides beneath the carbonate compensation depth (CCD) characterized the early Miocene, followed by middle Miocene-Pleistocene increased carbonate preservation, deepened CCD and tephra input from both the oceanic Izu-Bonin arc and the continental margin Honshu arc. The Izu-Bonin forearc basement formed in a near-equatorial setting, with late Mesozoic arc remnants to the west. Subduction-initiation magmatism is likely to have taken place near a pre-existing continent-oceanic crust boundary. The Izu-Bonin arc migrated northward and clockwise to collide with Honshu by early Miocene, strongly influencing regional sedimentation. ARTICLE HISTORY
