Tracing the subducting Pacific slab to the mantle transition zone with hydrogen isotopes by Takeshi Kuritani, Kenji Shimizu, Takayuki Ushikubo, Qun-Ke Xia, Jia Liu, Mitsuhiro Nakagawa, Hajime Taniuchi, Eiichi Sato, Nobuo Doi

“…However, further quantitative understanding is hindered due to a lack of observations about the changes in D/H ratios of a slab during subduction. Here, we report hydrogen isotope data of olivine-hosted melt inclusions from active volcanoes with variable depths (90‒550 km) to the subducting Pacific slab. …”

Venus’ light slab hinders its development of planetary-scale subduction by Junxing Chen, Hehe Jiang, Ming Tang, Jihua Hao, Meng Tian, Xu Chu

“…The simulation of slab buoyancy in 2-D models shows that Venus’ light slabs, due to a less eclogitized crust, experience more resistance to subduction. Thus, plate tectonics might have been more difficult to develop on Venus than on Earth.…”

Cold deep subduction recorded by remnants of a Paleoproterozoic carbonated slab by Cheng Xu, Jindřich Kynický, Wenlei Song, Renbiao Tao, Zeng Lü, Yunxiu Li, Yueheng Yang, Miroslav Pohanka, Michaela V. Galiova, Lifei Zhang, Yingwei Fei

“…Here, Xu et al. report a cold thermal-gradient recorded in an eclogite xenolith in Paleoproterozoic carbonatite from orogen, and propose that modern-style subduction has operated since at least the Paleoproterozoic.…”

Holocene Sedimentary Record and Coastal Evolution in the Makran Subduction Zone (Iran) by Raphaël Normand, Guy Simpson, Frédéric Herman, Rabiul Haque Biswas, Abbas Bahroudi

“…The western Makran coast displays evidence of surface uplift since at least the Late Pleistocene, but it remains uncertain whether this displacement is accommodated by creep on the subduction interface, or in a series of large earthquakes. …”

Heterogeneous slab thermal dehydration driving warm subduction zone earthquakes by Ye Zhu, Yingfeng Ji, Lijun Liu, Weiling Zhu, Rui Qu, Chaodi Xie, Haris Faheem, Shoichi Yoshioka, Lin Ding

“…Therefore, slab thermal dehydration plays a greater role than slab temperature condition in influencing the subduction earthquake distribution in warm subduction systems.…”

Barium content of Archaean continental crust reveals the onset of subduction was not global by Guangyu Huang, Ross N. Mitchell, Richard M. Palin, Christopher J. Spencer, Jinghui Guo

Subducted oceanic crust as the origin of seismically slow lower-mantle structures by Timothy D. Jones, Ross R. Maguire, Peter E. van Keken, Jeroen Ritsema, Paula Koelemeijer

“…We use existing global geodynamic models in which dense oceanic crust forms at divergent plate boundaries and subducts at convergent ones. The model suite covers the predicted density range for oceanic crust over lower mantle conditions. …”

Calcium isotope evidence for early Archaean carbonates and subduction of oceanic crust by Michael A. Antonelli, Jillian Kendrick, Chris Yakymchuk, Martin Guitreau, Tushar Mittal, Frédéric Moynier

“…Phase equilibrium modelling combined with Ca isotope measurements in ancient granitoids demonstrates that subduction of oceanic crust occurred repeatedly throughout the Archaean and that carbonate sediments were present in early Eoarchaean oceans (>3.8 billion years).…”
