Global radium (Ra) isotope data from ∼27 brine systems reveal Ra occurrence, transport, and applications. Elevated Ra activities exhibit spatial covariation with total dissolved solids (TDS), with significant proportions exceeding World Health Organization (WHO) standards and industrial limits. Quadruple Ra isotopes (²²⁶Ra, ²²⁸Ra, ²²⁴Ra, ²²³Ra) revealed salinity-dependent “ridge” patterns, indicating sequential desorption-precipitation controls. Global-scale Ra co-precipitation thresholds were determined as 102.33–128.82 g/L TDS through nonlinear logarithmic regression analysis. Short-/long-lived Ra ratios further decode dynamics governed by recoil, weathering and aquifer lithology. Elevated ²²⁸Ra/²²⁶Ra and ²²⁴Ra/²²⁸Ra ratios in coastal brines (∼40.8% and 65.0%, respectively) signal active seawater intrusion, whereas depleted ratios in inland system (∼59.8% and 36.0%, respectively) denote stable paleo-brine preservation. We design dual Ra mass-balance models quantifying modern intrusion rates (via ²²⁴Ra/²²⁸Ra) and paleo-brine ages (via ²²⁸Ra/²²⁶Ra), coupled with enhanced strategies. Despite model parameters and colloidal Ra transport uncertainties, this Ra-centric approach establishes a transferable framework for managing strategic brine resources in the Anthropocene.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"148 ","pages":"Pages 43-52"},"PeriodicalIF":7.2,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144764174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these gaps, this study employed a Deep Tabular Learning algorithm, specifically TabNet (Attention interpretable tabular learning), optimized using three metaheuristic algorithms: Particle Swarm Optimization (PSO), Cuckoo Search (CS), and Whale Optimization Algorithm (WOA) and land subsidence detection in Kurdistan Province, Iran, from 2015 to 2022, utilizing Interferometric Synthetic Aperture Radar (InSAR) time analysis. The spatial database for modeling integrated land subsidence occurrence areas was derived from InSAR data with 15 critical criteria, including topographic, climatic, geological, and land-cover information. The modeling results and susceptibility maps revealed that the TabNet-CS model exhibited the highest accuracy in predicting land subsidence susceptibility, with a Root Mean Square Error (RMSE) of 0.223, Mean Absolute Error (MAE) of 0.125, and Area Under the Curve (AUC) of 0.956.

This study systematically investigates newly discovered Neoproterozoic granites from the South Yellow Sea, integrating geochronological, geochemical, and isotopic data with published records from the Yangtze Block and the Gyeonggi Massif to decipher the origins and tectonic implications of Neoproterozoic extension-related magmatism within these blocks. The basement granites from the South Yellow Sea, dated to ca. 813–804 Ma, exhibit geochemical characteristics typical of A₂-type granites and are coeval with ca. 830–790 Ma A₂-type granitic magmatism in the Yangtze Block and Gyeonggi Massif. Geochemical and isotopic evidence suggests that most A₂-type granites in these regions originated from the partial melting of Paleoproterozoic metasedimentary rocks, with minor crust-mantle interaction and significant fractional crystallization. Some A₂-type granites in the Gyeonggi Massif, however, were derived from the melting of Paleoproterozoic mafic lower crust. These findings indicate that the ca. 830–790 Ma A₂-type granitic magmatism was closely associated with continent arc extension, likely triggered by slab rollback. The South Yellow Sea and Gyeonggi Massif likely represent the eastern extension of the Yangtze Block, forming part of a marginal arc system along the periphery of Rodinia.

While polarimetric synthetic aperture radar (PolSAR) data have been utilized to detect inundated regions, the information contained within PolSAR features remains severely underutilized. We introduce a novel approach that involves extracting a large number of PolSAR features through various PolSAR decomposition techniques, selecting the most important ones using the decision tree–recursive feature elimination (DT-RFE) method, and ultimately detecting inundation using a convolutional neural network (CNN) model. The hybrid DT-RFE–CNN model was trained and tested over a region in southeastern North Carolina during Hurricane Florence on September 18, 2018, using PolSAR features derived from the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). In terms of flood-mapping efficacy, the DT-RFE–CNN model outperformed a CNN model that used only PolSAR data across all metrics in both the training and testing stages. The performance of the trained DT-RFE–CNN model was evaluated by testing it over the same region for four more days (September 19, 20, 22, and 23, 2018); it achieved an average accuracy, precision, recall, F1 score, and intersection-over-union of 0.9304, 0.9089, 0.9584, 0.9324, and 0.8738, respectively outperforming both the classical Otsu method and the FT-Transformer model using features selected by DT-RFE. Finally, we assessed the model’s generalizability by mapping another significant flood event, caused by Hurricane Harvey in Texas between August and September 2017.
