Tectonic escape from the Pangean megamonsoon via oceanic isolation modulated low-latitude hydroclimate

Qiang Ren, Huaichun Wu, Anqing Chen, Jian Zhang et autres

The assembly of the Pangea supercontinent during the late Paleozoic ice age drove Earth’s most intense megamonsoon. Although climate models predict a humid low-latitude eastern Pangean margin, widespread red-bed records indicate extreme seasonal oxidation, creating a conspicuous “model-sediment” paradox. Located directly on …

Reversed marine phosphorus gradient in the Ediacaran Ocean

Matthew S. Dodd, Chao Li, Meng Cheng, Jun Hu et autres

The Ediacaran Period (635–539 Ma) witnessed the emergence of early animals, rapid oceanic oxygenation, and rising oceanic P availability. However, the relationships among these developments remain intensely debated. Here, we present high-resolution carbonate-associated phosphate (CAP) data from seven Ediacaran sections spanning diverse …

An auto-prompting Segment Anything Model for dual-modal grain segmentation in rock images

Yijun Wang, Dongyu Zheng, Mingcai Hou, Hongjun Li et autres

Accurate segmentation of particles in rock thin sections is essential for provenance reconstruction and sedimentary environment interpretation. The Segment Anything Model (SAM), a large-scale foundation segmentation model, has demonstrated strong performance and generalization across diverse domains. However, its application to petrographic image …

Subduction modulated the long-term oxygenation of Earth’s surface

Wei Shi, Chao Li, Benjamin J. W. Mills, Michael Brown et autres

On Earth, atmospheric oxygen is inferred to have risen over three major intervals before reaching modern levels, with each interval having a profound impact on the evolution of the biosphere. However, the principal driver behind these stepwise increases remains elusive. Here, we …

Tight regulation of Earth’s long-term temperature over Phanerozoic time

Dongyu Zheng, Alex G. Lipp, Alexander Farnsworth, Shufeng Li et autres

Knowing the past temperature of the Earth is crucial for understanding the mechanisms driving climate change and biosphere evolution, but there is significant debate about the range of past temperature variation. Previous interpretations, largely based on oxygen isotope records, suggest that global …

Arsenic substitution and galvanic coupling in pyrite trigger uranium mineralization in sandstone

Huijie Yu, Hao Song, Guoxiang Chi, Zhengqi Xu et autres

Abstract Sandstone-hosted uranium (U) deposits account for the majority of global U production. In these deposits, pyrite is widely considered one of the most common reducing agents playing a crucial role in ore formation. However, it has been shown that pyrite is …

An abrupt drop in weathering flux amplified the Artinskian Warming Event during the Late Paleozoic Ice Age

Shi Sun, Anqing Chen, James G. Ogg, Karem Azmy et autres

Contemporary glaciers are retreating at an alarming rate, an irreversible trend closely associated with ongoing global warming. Approximately 290 million years ago, Earth experienced a comparable large-scale glacial retreat, marking a pivotal transition of the Late Paleozoic Ice Age (LPIA) toward a …
