The heat released from the Earth’s interior to the surface has a significant impact on the future of our planet. Owing to the secular cooling of Earth, surface heat flux has gradually decreased throughout Earth’s history. The average surface heat flux would be subject to fluctuations in accordance with the supercontinent cycle on the order of 100 million years because the average age of the oceanic

Paleomagnetic consequence of thermal evolution of the North American Passive Margin: The Jurassic APWP controversy Gondwana Res. (IF 7.2) Pub Date : 2025-01-19 Masoud Mirzaei, Russell F. Burmester, Bernard A. Housen, Vadim A. Kravchinsky
This study revisits the long-standing controversy in selecting Jurassic paleomagnetic data to define the North American (NA) craton APWP. Data from igneous rocks in the eastern part of NA and select global data rotated into NA coordinates define a high-latitude path. In contrast, the data from mostly sedimentary rocks in the NA Southwest interior (southwestern group) describe a lower-latitude path

Impact of coastal industrialization and urbanization on marine phosphorus cycle: Insights from Daya Bay and Zhelin Bay Gondwana Res. (IF 7.2) Pub Date : 2025-01-19 Yang-Guang Gu, Ya-Su Wang, Richard W. Jordan, Yan-Peng Gao, Hong-Hui Huang, Shi-Jun Jiang
Coastal sediments serve as an important sink for phosphorus from terrestrial sources, yet the impact of coastal industrialization and urbanization on marine phosphorus cycling remains poorly understood. This study employs the Dual-Mode Diffusive Gradients in Thin Films (DGT) technique to investigate the interplay between dissolved reactive phosphorus (DRP), dissolved sulfide (S2−), and iron (Fe2+)

Enhancing long-term prediction of non-homogeneous landslides incorporating spatiotemporal graph convolutional networks and InSAR Eng. Geol. (IF 6.9) Pub Date : 2025-01-18 Zongzheng Li, Jianping Chen, Chen Cao, Wen Zhang, Kuanxing Zhu, Ji Bai, Chenyang Wu
Accurately predicting landslides is critical for effective warning and management, but remains challenging due to unpredictable triggering events and the spatial heterogeneity of soil and slope structures. Existing prediction methods often rely on point-sampled data, neglecting the heterogeneity in landslide evolution. To address this, we propose integrating Spatiotemporal Graph Convolutional Networks

Research and monitoring on the water-heat-gas behavior and frost heaving characteristics of coarse-grained fillers under unidirectional freezing conditions Eng. Geol. (IF 6.9) Pub Date : 2025-01-16 Haihua Zhang, Haojin Zhang, Zhenghao Liu, Xianfeng Ma, Jiangu Qian
Gaseous water migration is a crucial factor in the development of frost heaving in coarse-grained fillers. The goal is to study the gaseous water migration and frost heaving characteristics of coarse-grained fillers. Based on the law of light reflection and refraction, Polymer optical fiber (POF) sensors are proposed to monitor the light intensity in the fillers during the freezing process, so that
