Rodingite‐Derived Melt as a Recipe for Ultra‐Calcic Magmas

Mingdi Gao, Yu Wang, Shi-Dong Guan, Yi‐Xiang Chen et autres

Abstract Rodingite is a high‐CaO rock formed by Ca‐rich fluid metasomatism on mafic protoliths. It typically occurs within serpentinite and represents an often‐overlooked constituent of the altered oceanic lithosphere that may be subducted into the mantle. However, the fate of rodingite in …

Oxygen‐Deficient Magnetite in Chang’e‐6 Sample as Evidence for Impact Induced Deoxygenation of the Moon

Shengdong Chen, Xiaoju Lin, Haiyang Xian, Jianxi Zhu et autres

Abstract The Moon’s highly reduced nature contrasts with recent findings of ferric iron (Fe 3+ )‐bearing phases, suggesting an active redox cycle on the Moon. While solar wind proton reduction and impact‐vaporization oxygen loss from minerals are proposed drivers for lunar reduction, …

Heterogeneous stagnant slab controls focused crustal recycling and volcanic clustering

Sheng Zhu, Yangfan Deng, Yi‐Gang Xu, Yun Chen et autres

Stagnant slabs transport cold, hydrous, and compositionally distinct materials into the mantle transition zone (MTZ). Intraplate volcanism above these slabs documents the geochemical imprints of recycled subducted components. Yet the recycled mechanism remains elusive, largely because slab geometry and thermochemical state within …

The bombardment history on the lunar farside revealed by 40 Ar/ 39 Ar geochronology of Chang’e-6 impact melt rocks

Wanfeng Zhang, Le Zhang, Mang Lin, Fred Jourdan et autres

The reconstruction of the lunar bombardment history is pivotal to understanding the evolution of Earth-Moon system. So far, it heavily depends on geochronological studies of lunar nearside samples but lacks direct sample constraints from the lunar farside. Here, we present 28 single-clast …

Modulation of intra-oceanic trench bending and along-trench thermochemical transport by mantle toroidal flow

Liang Liu, Zebin Cao, Jason P. Morgan, Lijun Liu et autres

Oceanic trench bending over 1000 km occurs globally, with notable along-trench variations in mantle wedge thermochemistry. However, the mechanisms influencing both shallow trench geometry and deep mantle state remain unclear. Here we focus on the Mariana Trench as a representative case. Our …

Hydrogen peroxide on Mars and icy moons: Implications for the search for extraterrestrial signatures of prebiotic chemistry

Mang Lin, Ruiqin Yi, Albert C. Fahrenbach, H. James Cleaves et autres

ABSTRACT Hydrogen peroxide (H 2 O 2 ) is increasingly recognized as an important molecule in prebiotic chemistry that potentially had a large impact on life’s early evolution. We highlight recent examples of H 2 O 2 in prebiotic syntheses that model …

Transformation of Refractory Oceanic Lithospheric Mantle by Reactive Melt Infiltration: An Experimental Study on the Roles of Temperature, Melt Volume and Ascent Velocity

Yong-Sheng Hou, Hongyan Li, Chao Zhang, Yu Wang et autres

Abstract Reactive melt infiltration critically modifies the physical and chemical properties of the oceanic lithospheric mantle (OLM). This process, involving melt‐rock reactions and in situ crystallization, exhibits substantial spatial and temporal variability driven by melt volume and ascent velocity. To explore how …

KREEP‐Bearing Noritic Lower Crust Under Apollo Basin: Constraints From High‐Mg Impact Glasses in Chang'e‐6 Soil

Le Zhang, Jingyou Chen, Zexian Cui, Yuqi Qian et autres

Abstract The Moon's crust is proposed to be composed of an anorthositic upper crust and a noritic lower crust. While the upper crust was the result of the floatation of plagioclase crystallized at the late‐stage of lunar magma ocean (LMO), the petrogenesis …

Seismic Constraints on the 3‐D Magma Conduit System of Mount Etna

Siwen Zhang, Yuanyuan Hua, Dapeng Zhao, Yi‐Gang Xu et autres

Abstract Mount Etna, one of the most active volcanoes in the world, provides an excellent natural laboratory for investigating magma plumbing systems. However, previous models of Etna's volcanic structure have not adequately resolved the distribution of deep magma conduits. In this work, …
