Moreover, the imperative to adapt to frequently changing climate is at the heart of sustainable development goals. Understanding the dire need for adaptation technologies as an essential tool for building resilience and enhancing the load capacity factor to raise environmental quality, the present study focuses on the group of eight (G8) industrialized countries over the period from 1990 to 2020, to explore the role of adaptation technologies (ATEC) and green energy (REC) on the environmental quality (LCF). The empirical outcomes generated through Panel Quantile Regression (PQR) verify the existence of the LCC hypothesis in highly industrialized economies. The results show that ATEC positively and significantly affects LCF with an increasing rate from middle to upper quantiles. In contrast, REC has continuously an increasing impact throughout the quantiles with high significance. The robust outcomes are also endorsed by employing Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS). The study takes into consideration several Sustainable Development Goals (SDGs) like SDG 09 (adoption of technologies), SDG 07(green energy and renewable energy consumption), SDG 13 (climate action), SDG 14 (life below water), SDG 15 (life on land), SDG 03 (good health and well-being), SDG 06 (clean water and sanitation), SDG 11 (sustainable cities and communities), SDG 12 (responsible consumption and production), and SDG 17 (partnership for goals) while formulating policy implications, particularly for G8 economies.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"139 ","pages":"Pages 230-242"},"PeriodicalIF":7.2,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935472","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}

Energy R&amp;D expenditures can ensure that low-carbon energies are used at a rate close to their potential by increasing energy efficiency and reducing losses during the production and consumption phases. The positive environmental impacts of low-carbon energy and energy R&amp;D expenditures can be accelerated by political globalization. As an example of political globalization, the Kyoto Protocol has enabled the adoption of clean technologies and low-carbon energies by providing various obligations to many countries, especially developed countries. Although some countries have withdrawn from the obligations embodied in the protocol, they are taking measures to ensure environmental sustainability through individual efforts in their own interests. The USA is the example that best reflects this. The environmental impact of energy security may vary depending on the energy sources that provide affordable and accessible energy. This study examines the effects of energy R&amp;D expenditures, political globalization, energy security, and low-carbon energy consumption on the USA’s load capacity factor and ecological footprint from 1980 to 2018 using Fourier-based FMOLS and CCR estimators. The robust results of this study show that low-carbon energy consumption, energy technology R&amp;D expenditures, and political globalization increase environmental sustainability. Policymakers should allocate more resources to developing low-carbon energy sources, increasing energy efficiency, and encouraging the adoption of clean energy technologies.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"139 ","pages":"Pages 221-229"},"PeriodicalIF":7.2,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905673","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}

However, the activity in these areas was not synchronous, and the potential connection between both sectors along the Gondwana margin and its meaning is still poorly understood. U-Pb geochronology performed on detrital zircon grains of the Ediacaran Serie Negra Group (SW Iberia) show a maximum depositional age between 619 and 559 Ma for its Montemolín and Tentudía formations, respectively. The obtained Hf data from the same zircon grains supports significant crustal input. Meanwhile, U-Pb performed on detrital zircon grains of the Cambrian Betanzos Unit (NW Iberia) exhibit essentially mantle-derived Hf signature at 544–537 Ma (Maximum Depositional Age). Based on these data, a dynamic model for the Gondwana margin at c. 500 Ma has been proposed, comparable to the current processes operating on the Pacific edge of the North American plate.

Sedimentologic and U-Pb detrital zircon geochronological results for the Silurian Rinconada Formation and Carboniferous Jejenes Formation of the eastern Precordillera provide insight into sediment provenance, drainage reorganization, and climatic/tectonic interactions during Paleozoic deformation and glaciation. Measured sections and lithofacies analyses indicate sediment gravity flow and mass-transport deposition in a Silurian submarine fan during shortening in the adjacent Famatinian orogenic belt. This foreland basin was deformed during the Late Devonian Chanic orogeny, prior to glacial incision of remnant topography during the Late Paleozoic Ice Age. Analyses of unconformities, cross-cutting relationships, and lithofacies within a Carboniferous paleovalley (Quebrada Grande, Sierra Chica de Zonda) indicate four facies associations (fjord-head delta, distal fjord, fan delta, and subglacial fan) within a fjord setting governed by glacial advance and retreat. U-Pb results for Carboniferous sandstones (7 samples, 840 analyses) indicate derivation from Western Pampean basement with progressive drainage expansion to include the Famatinian magmatic arc and Eastern Sierras Pampeanas. Evolution from a Silurian marine foreland basin to an isolated Carboniferous fjord reflects major orogenic and climatic transitions in SW Gondwana. Ordovician-Silurian (Famatinian) and Late Devonian (Chanic) shortening generated topography that was subsequently beveled by glacial erosion during the Carboniferous. We suggest that Paleozoic deformation related to subduction and terrane collision helped drive changes in sediment dispersal and basin configuration, while climate changes during regional glaciation regulated erosion/deposition and the spatial extent of sediment accommodation.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"139 ","pages":"Pages 179-203"},"PeriodicalIF":7.2,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results show that the Moho depth gradually increases from ∼35 km beneath the Songliao basin to ∼40 km beneath the Great Xing’an Mountains. In the vicinity of the North-South gravity lineament, the Moho is slightly inclined with a continuous depth of ∼5 km, which forms a transition zone from the basin to the orogenic belt. A middle crustal discontinuity, or the Conrad discontinuity, is imaged beneath the Songliao-Xilinhot block and the northern margin of the North China Craton. The Conrad and Moho discontinuities beneath the suture zones show traces of bidirectional subduction of the Paleo-Asian Ocean plate. Meanwhile, we find subtle changes in the receiver functions due to variations in the sedimentary layer thickness. The sedimentary layer beneath the southern Songliao basin is estimated to be ∼1.2 km thick and it thins toward its edge. Moreover, we find a middle lithospheric discontinuity below the Moho under the Songliao-Xilinhot block.
