Subduction initiation is a key process for global plate tectonics. Individual lithologies developed during subduction and arc inception have been identified in the trench wall of Izu–Bonin–Mariana (IBM) island but continuous record this has not previously described. Here, we present results from International Ocean Discovery Program Expedition 351 that drilled single site west Kyushu–Palau Ridge (KPR), chain extinct stratovolcanoes represents proto-IBM arc, active ∼25 Ma following...
The magmatic character of early subduction zone and arc development is unlike mature systems. Low-Ti-K tholeiitic basalts boninites dominate the Izu-Bonin-Mariana (IBM) system. Basalts recovered from Amami Sankaku Basin (ASB), underlying located west IBM's oldest remnant arc, erupted at ~49 Ma. This was 3 million years after inception (51-52 Ma) represented by forearc basalt (FAB), tipping point between FAB-boninite typical magmatism. We show ASB are low-Ti-K, aluminous spinel-bearing...
The study of pressure stimulated current (PSC) changes rocks is significant to monitor dynamic disasters in mines and rock masses. existing studies focus on change laws mechanism currents generated under the loading rocks. An electrical mechanics test system was established this paper explore impacts rates PSCs. results indicated that PSC curves different had low/high rates. When rate relatively low, firstly changed gently then increased exponentially. Under high rates, experienced rapid...
The driving forces of plate motion, especially that its sudden change over time, has long been debated. During the closure an old ocean, subduction process mid-ocean ridge provides valuable clues to quantitative evaluation tectonics. Here we show drifting rates Indian were correlated with a Late Cretaceous adakitic event hosting abundant adakites and charnockites in Gangdese belt, southern Tibetan Plateau. While form through slab melting, ultra-high temperatures dry nature indicate major...
Abstract A‐type granite is a favorable rock for the study of crustal evolution, crust‐mantle interaction and metallogenesis. However, origin remains controversial. In this study, we report high‐precision Ca isotopic compositions co‐genetic suite granites from Lower Yangtze River Belt (LYRB) in eastern China. Our results show that δ 44/40 ranges 0.55 ± 0.11‰ to 1.44 0.06‰, negatively correlated with CaO, Sr Ba contents Eu/Eu*, indicating isotope fractionation dominated by plagioclase...
Wearable pressure sensors capable of adhering comfortably to the skin hold great promise in sound detection. However, current intelligent speech assistants based on can only recognize standard languages, which hampers effective communication for non-standard language people. Here, we prepare an ultralight Ti
Abstract International Ocean Discovery Program (IODP) Expedition 351 ‘Izu–Bonin–Mariana (IBM) Arc Origins’ drilled Site U1438, situated in the northwestern region of Philippine Sea. Here volcaniclastic sediments and igneous basement proto-IBM volcanic arc were recovered. To gain a better understanding magmatic processes evolution arc, we studied melt inclusions hosted fresh minerals sampled from 30–40 Myr old deposits, reflecting maturation volcanism following subduction initiation at 52 Ma....
Abstract The oldest known, intact sedimentary record of a nascent intraoceanic arc was recovered in ∼100-m-thick unit (IV) above ca. 49 Ma basaltic basement at International Ocean Discovery Program Site U1438 the Amami Sankaku Basin. During deposition Unit IV site located ∼250 km from plate edge, where Izu-Bonin-Mariana subduction initiated 52 Ma. Basement basalts are overlain by mudstone-dominated subunit (IVC) with thin basal layer dark brown metalliferous mudstone followed sparse, graded...
