We report new chemical and Mg–O isotopic data on high-MgO mantle eclogites from the Obnazhennaya kimberlite, Siberia craton. Obnazhennaya high-MgO eclogites have lower bulk δ<sup>26</sup>Mg isotopes (-1.47– -0.36‰) and mantle-like garnet δ<sup>18</sup>O isotopes (+5.18–+6.39‰). A bulk mixing calculation among oceanic crust, carbonate sediment and kimberlite, and its effects on Mg isotopes and MgO content indicate that metasomatism can only increase the MgO content but not δ<sup>26</sup>Mg, and more than 50% dolostone by mass is needed, under conditions with no kimberlitic melt metasomatism, to account for both high-MgO contents, which is unrealistically high for natural settings. The ternary mixing model on both O–Mg isotopic compositions and MgO–Mg isotopic compositions suggest that subducted oceanic crusts modified by mantle metasomatism (e.g., kimberlite-like melt) as well as carbonate sediments involvement collectively provides the best explanation for such a high magnesian origin. This model is also compatible with global mantle eclogite observations, where there is also a clear chemical composition distinction between high- and low-MgO eclogites globally. In light of our new results and global compilation, we propose that mantle eclogites represent a spectrum of metasomatized subducted oceanic crust with variable amounts of the involvement of carbonate sediments, the latter of which represents a novel ingredient in the recipe for making previously enigmatic high-MgO eclogite xenoliths in kimberlites.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"153 ","pages":"Pages 60-72"},"PeriodicalIF":7.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145759822","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}

The current understanding of forearc deformation is largely based on numerical models with limited, field-based input data from small areas. This paper therefore presents a reconstruction of tectonic deformation in this region based on two topographic profiles across the entire continental forearc. The forearc overlying the ridge crest and leading edge hosts the large Quaternary Nazca Peneplain (QNP), which has registered uplift and deformation since the onset of ridge subduction. We developed a Conditional Variational Autoencoder (CVAE) deep learning model to reconstruct the QNP to its pre-eroded state and used this surface as input for two retrodeformed topographic profiles. The QNP and adjacent marine terraces were then dated using cosmogenic nuclide exposure and luminescence methods and used to calculate deformation rates. Forearc deformation involves uplift primarily due to folding, with basal thrusting or buoyancy of the Nazca Ridge acting as secondary drivers. Shortening rates since 1.85 ± 0.18 Ma to the present range from 0.32 to 0.36 mm a<sup>-1</sup>, and surface uplift rates up to 0.37 mm a<sup>-1</sup>. The 1.85 ± 0.18 Ma age combined with a regional bounding surface between shallow marine and fluvial gravels, provides an estimate for the timing of Nazca Ridge-overriding plate coupling. These results align with, and refine, previous numerical predictions on forearc deformation due to buoyant ridge subduction and offer a high-resolution dataset for future studies.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"153 ","pages":"Pages 323-343"},"PeriodicalIF":7.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145893890","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}

Drawing on robust methodologies—including principal component analysis, correlation analysis, and regression models with Driscoll-Kraay and panel-corrected standard errors—the analysis identifies energy transition, population density, freshwater withdrawals, industry value added, and GDP per unit of energy use as critical determinants of energy efficiency. The results reveal that a progressing green energy transition significantly enhances energy efficiency, indicating the positive role of clean energy integration and grid modernization. Grid modernization upgrades the power grid with technologies like smart meters, energy storage, and real-time monitoring to manage renewables more efficiently and reduce energy losses. Similarly, higher population density modestly improves energy efficiency, likely through urban economies of scale and compact infrastructure. Increased freshwater withdrawals lower energy efficiency, linked to water-intensive processes like cooling systems and manufacturing. Industrial development boosts efficiency, emphasizing the need for technological upgrades and process optimization. However, GDP per unit of energy use shows a negative relationship with energy efficiency, indicating a disconnect between economic productivity and technical energy performance. The findings underscore the importance of holistic and cross-sectoral policy approaches that simultaneously address energy, water, and urban planning challenges.

These models also generate future climate projections based on shared socioeconomic pathways (SSPs), aiding in risk assessment and the development of costly “Net-Zero” climate mitigation strategies. Yet, as this study discusses, the CMIP GCMs face significant scientific challenges in attributing and modeling climate change, particularly in capturing natural climate variability over multiple timescales throughout the Holocene. Other key concerns include the reliability of global surface temperature records, the accuracy of solar irradiance models, and the robustness of climate sensitivity estimates. Global warming estimates may be overstated due to uncorrected non-climatic biases, and the GCMs may significantly underestimate solar and astronomical influences on climate variations. The equilibrium climate sensitivity (ECS) to radiative forcing could be lower than commonly assumed; empirical findings suggest ECS values lower than 3 °C and possibly even closer to 1.1 ± 0.4 °C. Empirical models incorporating natural variability suggest that the 21st-century global warming may remain moderate, even under SSP scenarios that do not necessitate Net-Zero emission policies. These findings raise important questions regarding the necessity and urgency of implementing aggressive climate mitigation strategies. While GCMs remain essential tools for climate research and policymaking, their scientific limitations underscore the need for more refined modeling approaches to ensure accurate future climate assessments.

The obtained spillover effects reveal a significant total connectedness within the system. Notably, domestic aviation is identified as the leading contributor of spillover shocks to all other sources, demonstrating its pervasive influence across the CO<sub>2</sub> emission network. Furthermore, the transmission of return spillovers is more pronounced in the left and right tails of emissions from residential, transportation, industrial, and domestic aviation sectors, indicating increased interconnectedness during periods of extreme market events. The results specifically show that at lower quantiles, transportation (domestic aviation) serves as a contributor (receiver) of spillover shocks, while at the 90th quantile, domestic aviation becomes the sole contributor of shocks to all other variables, and they switch positions. These insights are crucial for policymakers, as they underline the need for targeted and flexible climate policies that take into account the varying roles of emission sources under different conditions of market volatility.
