To address this research gap, the main objective of the study is to examine the three perspectives of sustainability across the US, China, and Indonesia to reveal their most dominant sustainability perspective. To this end, it maps the spatial spillovers of sustainability pillars, including social, environment, and economy, within the sample countries. For this mapping, this approach estimates the sustainability elasticities using the SEY model, which involves the Vector Autoregression (VAR), simultaneous equations system, and causal examination, within 1974–2020. The results indicate that the elasticities of sustainability are mainly high and synergistic, meaning that the sustainability pillars mainly have considerable and synergistic spillover effects. This finding accepts the integrated sustainability while refusing the perspectives of strong and weak sustainability. Moreover, the findings denote that the flowing patten of spillovers have a spatially symmetric distribution between the US and China, attaching equal importance to the relationships with the western and eastern economies of the world. The theoretical implication of the findings is that they introduce spillovers as the 4th dimension of sustainability, completing the three classical dimensions of economy, environment, and social in the context of the weak and strong perspective of sustainability. From the perspective of policy recommendation, the findings suggest decision-makers in Indonesia to promote peaceful, strong, and balanced ties with the great economic powers in the west and the east like the US and China.","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"51 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515691","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 Urucum and Itatiaia pegmatites exemplify this late-stage magmatic evolution, displaying distinct geochemical and isotopic signatures reflecting their different fractionation degrees, crustal contamination, and parental melt evolution. We investigate their petrogenesis through U-Pb geochronology, trace element geochemistry, and Sm-Nd isotope analyses of apatite, cassiterite, and zircon to refine their genetic relationships with associated granitic systems and assess the role of partial melting, fluid-rock interaction, and post-collisional magmatism in pegmatite genesis. Our results indicate a temporal and genetic decoupling between the pegmatites and their associated granites, with pegmatite crystallisation occurring ∼ 50 Ma after granite emplacement. The EBPP cannot be explained solely by fractional crystallisation but rather involves partial melting and crustal remobilisation during the post-collisional stage. The Itatiaia pegmatite exhibits an evolved geochemical signature, suggesting a distinct melt evolution influenced by crustal contamination, while the Urucum pegmatite retains geochemical characteristics similar to the G3 S-type granites. Nd isotopic data support a Paleoproterozoic crustal source, with pegmatites forming during the post-collisional stage of the Araçuaí orogen (∼530 Ma).

However, it remains enigmatic how backarc basins contribute to crustal reworking. The Hongliuhe–Xichangjing Ocean (HXO), as a significant Early Paleozoic branch of the Paleo-Asian Ocean, has sparked considerable debate regarding the timing and processes of its formation and closure. This study proposes a Wilson cycle for the HXO, based on sedimentary sequences and provenances from two accretionary complexes along its margins. On the southern margin, the detrital zircon age spectra of Cambrian to Early Ordovician strata are bimodal with age peaks at ca. 980 and 2440 Ma derived from the Dunhuang and Shuangyingshan blocks. The age spectra of Late Ordovician strata are unimodal with age peaks at 472–458 Ma, showing derivation from a juvenile arc on the Shuangyingshan block. On the northern margin, the age spectra of Cambrian strata are bimodal with the age peaks at 558 Ma and 671 Ma sourced from volcanic arcs near the Tuva-Mongolia block. In the Silurian, the age spectra shift to unimodal pattern with age peaks at ca. 441–451 Ma, showing their derivations from the Gongpoquan arc. The differences in source areas of both margins in the Cambrian indicate the existence of HXO, while the provenance shift from Cambrian to Middle-Late Ordovician reveals that they both transformed from passive margin to active continental margins. The Wilson cycle involves backarc spreading during the Early Cambrian, oceanic extension from the Middle Cambrian to Early Ordovician and bipolar subduction from the Middle Ordovician to Late Carboniferous. The formation of HXO and subsequent backarc expansion resulted from its bipolar subduction fragmented the uniform continent, which is a key mechanism for crustal reworking in the Altaids. Resurrected subduction of the HXO produced accretionary complexes, leading to lateral crustal growth.","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"27 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515593","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}

Spatial isotopic variations are particularly evident in the western front of the orogen (western H.U. Sverdrupfjella) in contrast to other regions. The former exhibits a wide range of isotopic compositions, with the majority showing highly evolved signatures, indicating that the orogenic crust developed through the reworking of pre-existing Archean–Paleoproterozoic continental crust. In contrast, most other regions of the Maud Belt are characterized by relatively juvenile Hf and Nd isotopic compositions, which are interpreted to be derived from a mixture of juvenile magmas and Paleoproterozoic crust. The Hf isotopic evolution from 1180 Ma to 950 Ma indicates significantly less reworking of pre-existing continental crust compared to other contemporaneous Rodinia-forming orogens, including the Grenville Orogen itself, and emphasizes a predominant addition of juvenile material, implying a continuous subduction process. The isotopic investigation in this study, combined with the geological and paleomagnetic evidence, indicates that the Maud Belt most likely represents an exterior accretionary orogen along the eastern margin of the Proto-Kalahari Craton, rather than being part of the continental collision zones that led to Rodinia amalgamation.</div></div>","PeriodicalId":12761,"journal":{"name":"Gondwana Research","volume":"146 ","pages":"Pages 235-251"},"PeriodicalIF":7.2,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515594","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}
