In rifts developed in relatively cold lithosphere (e.g. East African Rift) inherited fabrics are predominantly old (Precambrian), widely separated in time from rifting. Rift location is strongly linked to where lithospheric mantle strength is reduced by deep mantle processes. Conversely, in Thailand (SE Asia) Cenozoic rifting developed in hot lithosphere (upper plate of major subduction zones), inherited fabrics comprise a highly diverse range of types (folds, thrusts in Phanerozoic sequences, gneiss domes, granite plutons, metamorphic foliations, strike-slip faults) that formed primarily during the Triassic (Indosinian Orogeny), Late Cretaceous and Paleogene. The orogenic development of gneiss domes in Thailand has parallels with Caledonian structures below the northern North Sea rifts. Rift location is controlled by the area of weakest crust, i.e. the Indosinian Paleotethys suture zone. Rift mode in Thailand varies from wide to narrow to core complex not only in response to crustal conditions (temperature, thickness), but also to local magmatism and fabric inheritance (major Indosinian detachment zones). The wealth of fabrics in Thailand influenced the location, dip direction, dip value, strike orientation, propagation and linkage history, fault length-displacement characteristics, fault population size distribution and map-view patterns of normal faults. Fabric influence on Thailand's rift basins is important to identify for a variety of reasons including: 1) as an extra factor to crustal thickness and geothermal gradient that influences rift mode, 2) as a major control on rift location, 3) as means of explaining atypical fault patterns in rift basins, and thereby supporting an extensional origin, rather than an escape-tectonics related strike-slip origin, 4) as a major influence on the characteristics of individual rift basins and how structures of economic importance have developed. 5) Causing fault populations to evolve in a variety of ways during the rift initiation phase.

Despite the impact of BCEs as natural climate solutions, the mechanisms responsible for carbon retention have not been clearly summarised, limiting our chance to manage BCEs for maximum carbon storage. Here, we explore a great mystery of the blue carbon cycle by reviewing existing published literature: Why is some coastal carbon remineralised into CO₂ and CH₄ by microbes within seconds/min while other carbon escapes microbial attack and becomes sequestered for millennia? The answer to this question will help predict and manage the global blue carbon cycle. We find that microbial communities are fundamental drivers of carbon mineralisation in BCE sediments, with their metabolic pathways dictating the fate of sequestered organic matter. Contrary to earlier notions, microbial diversity and composition are shown to significantly impact carbon stabilisation, with distinct microbial taxa targeting different organic compounds. Furthermore, anthropogenic disturbances such as habitat alteration and eutrophication can disrupt microbial communities, leading to increased carbon mineralisation and CO₂ and CH₄ emissions. Environmental parameters such as temperature, salinity, and nutrient availability also exert considerable influence on carbon stability in BCEs. Changes in these factors can alter microbial activity and the degradation rate of organic matter, highlighting the importance of understanding their additive and synergistic effects. For instance, warming combined with oxygen exposure due to habitat disturbance can amplify microbial carbon mineralisation, particularly in submerged BCEs like seagrass beds. Future research directions include characterising carbon at molecular levels, understanding region-specific drivers of carbon stability, and prioritising conservation efforts based on physiographic and geomorphologic settings. This review underscores the need for a holistic approach to BCE management, considering both microbial processes and environmental factors. By elucidating the factors governing carbon stability, this study aims to enhance our understanding of the role of BCEs in climate change mitigation and inform conservation strategies.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"265 ","pages":"Article 105133"},"PeriodicalIF":10.8,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824119","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}

This review presents a methodology for comparing EGMS Ortho (Level 3) data, based on Sentinel-1, and calibrated with measurements from the Global Navigation Satellite System (GNSS) and long-term rates based on the markers of the Marine Isotope Stage (MIS 5.5; Late Pleistocene). This study examines the Italian and Greek coasts, encompassing a range of geodynamic settings. In stable crustal segments, such as Sardinia, the EGMS Ortho (Level 3) data roughly align with both GNSS and post-MIS 5.5 rates. However, long-term based observed variations are considerably below the current 1 mm/yr EGMS precision. Conversely, in foreland basins, EGMS maps show higher values than GNSS data, which reflect regional interactions between ongoing tectonics and compaction. Local discrepancies between EGMS and GNSS in industrialized areas are attributable to industrial activities, as evidenced by the EGMS subsidence rates (8 mm/yr) observed in Ravenna, which exceed regional long-term estimates (0.8 mm/yr). In seismically active regions, such as Calabria and Sicily (e.g. the Messina Strait), the data reveals complex short- and long-term interactions linked to the seismic cycle. Conversely, in volcanic areas, like Campi Flegrei, Mt. Etna, Santorini and Nisyros, the EGMS data proves most valuable for highlighting complex volcano-tectonic movements.

The mechanisms of this so-called <em>necking phase</em> are incompletely understood, and yet they have major implications on the structural, thermal and isostatic evolution of rift systems. One major difficulty in studying the necking phase arises from its transient character in the framework of continental rifting, and from the subsequent extension and thermal relaxation that may overprint it. Consequently, the fingerprints of the necking process are partially dismembered and overprinted in present-day rifted margins, and hence are poorly constrained.</div><div>In this contribution, we synthesize data from the best calibrated necking domains worldwide to define general recognition criteria and identify the processes controlling the necking phase. We show that the necking domain of rifted margins usually displays the following body of evidence: (1) deformed basement directly overlain by undeformed syn-rift sediments; (2) exhumation of relatively deep continental crust; (3) syn-rift basement erosion and adjacent sandstone deposition; and (4) syn-rift and <em>syn-tectonic</em>/<em>syn</em><em>-kinematic</em> shallow-water sediments directly overlain by syn-rift but <em>post-tectonic/post-kinematic</em> deeper-water deposits. We assert that the combination of these fingerprints cannot be explained by the classical high-angle normal fault model by itself and discuss the possible additional and/or alternative processes.

The TFTB includes accreted oceanic sediments and magmatic rocks, supra-subduction ophiolites and fore-arc and back-arc siliciclastic rocks of Cambrian to Silurian ages. There remains a deficiency in data from magmatic rocks of the TFTB and, as a result, the timing of magmatism, mantle sources and tectonic settings are still debatable and the general early Paleozoic evolution of the TFTB is not fully understood. In this paper we review previous geological and age data (U-Pb, microfauna) and present new geological, geochronological (U-Pb zircon ages) and geochemical data and first isotope data (Sm-Nd, Pb-Pb, Lu-Hf). We discuss these new results and the previously reported, but still limited data from both magmatic and clastic rocks. Granite and rhyolite yielded middle-late Ordovician U-Pb zircon ages, 462 and 449 Ma, respectively. There are three main groups of volcanic/subvolcanic and plutonic rocks: (1) high-Ti, (2) mid-Ti, and (3) low-Ti. The high-Ti basalts and andesites are enriched in high-field strength elements (HFSE) and light rare-earth elements (LREE); they were derived at 2–4 % melting of an enriched garnet-bearing peridotite (εNd_t = +2.1… +6.8; ²⁰⁶Pb/²⁰⁴Pb = 19.2–22.8) and erupted on an oceanic island or seamount. The mid-Ti gabbro is N-MORB formed from a 15 % melted depleted mantle source (εNd_t = +8.1; ²⁰⁶Pb/²⁰⁴Pb = 18.9). The low-Ti group is depleted in HFSE, but not LREE, and formed at high degrees of melting (15–30 %) of depleted and ultra-depleted mantle sources (εNd_t = +6.1… +10.8; εHf_t = +17.6… +19.3) suggesting their emplacement in a supra-subduction setting. Based on all the available data, we present a model of double-sided subduction in this part of the PAO, which generated four intra-oceanic arcs at its opposite sides: early-middle Cambrian and Early Ordovician on one side and Early and Late Ordovician on another side. The early-middle Cambrian and Early Ordovician arcs were tectonically eroded and their fragments have been preserved in blocks of mélange and greywacke sandstones only. The pieces of all arcs were tectonically juxtaposed in the TFTB during the processes of subduction and accretion in the PAO.

This study established a new dataset including 200 high-quality Northern Hemisphere records focused on the 4.2 ka event, selected based on chronological control points, temporal resolution, and proxy significance. According to the amplitude and duration of hydroclimatic change of individual records within the 4.2 ka event, 130 of the 200 records experienced hydroclimatic excursions. While slight overall drying (73 out of 130 records) is observed in the Northern Hemisphere, evident spatial heterogeneity of hydroclimatic change is detected, with North-South dipole patterns over the East Asian monsoon and Europe-circum Mediterranean regions, as well as an East-West dipole pattern over North America. This emphasizes that drying and wetting both represent hydroclimatic characteristics of the 4.2 ka event. Furthermore, this study assessed the intensity of hydroclimatic change during the 4.2 ka event across different regions in the Northern Hemisphere for the first time, which weakened from western to eastern Eurasia. Given that the Pacific forcing shifted only after the onset of the 4.2 ka event, we propose that the event was initially triggered by North Atlantic forcing, with Pacific forcing subsequently amplifying its impact. These two forcings jointly contributed to the pronounced spatial heterogeneity of hydroclimatic change during the event, highlighting a fundamental characteristic of hydroclimatic variability.

Reconstructing the BNTO's evolution is crucial for understanding the accretionary history of the constituent blocks of the Tibetan Plateau prior to Cenozoic India-Asia collision. This paper reviews Mesozoic magmatism in the southern Qiangtang block (SQB) (north of the BNSZ) and beyond, as well as ophiolites and oceanic plateau material within the BNSZ, to assess the BNTO's evolution from its opening to closure. Combined with the ∼285 Ma southern Qiangtang-Panjal large igneous province, ∼278 Ma embryonic oceanic crust, and stratigraphy and biotas, we suggest that the BNTO opened during the Early Permian. This opening was the result of the rifting of East Cimmerian continental fragments from Gondwana's northern margin. After the Lhasa block separated from Gondwana, the BNTO was located between SQB to the north and the Lhasa block to the south. The widespread arc-related magmatic rocks in SQB indicate that the BNTO was subducted northwards. The initial subduction of the BNTO likely occurred during the Late Triassic, as strongly evidenced by the Mugagangri Group accretionary wedge. An integrated study of stratigraphy and magmatism suggests that the BNTO probably underwent a diachronous closure: the middle segment may have closed in the Early Cretaceous (133–120 Ma) while the western segment may have closed in the Albian (113–105 Ma). The intra-oceanic subduction and oceanic-continental subduction likely occurred during Early Jurassic. Then the widespread subduction-related ophiolites indicate that a late Early Jurassic (∼177 Ma) collisional orogeny occurred between the oceanic plateau and southern Qiangtang, resulting in intra-oceanic subduction. However, the oceanic plateaus in the BNTO have two contrasting fates: they were either accreted to SQB in the middle segment to clog the oceanic-continental subduction zone, or were subducted beneath SQB in the western segment to induce the 177–169 Ma flat-slab subduction. The 169–145 Ma magmatism and 145–125 Ma magmatic gap in western SQB can be explained by the second subduction of the oceanic plateau or/and ridge subduction. The &lt;125 Ma renewed magmatism may be the result of slab rollback and breakoff.&lt;/div&gt;&lt;div&gt;This oceanic plateau subduction may contribute to the formation of the Early Cretaceous porphyry Cu deposits in SQB but this requires more research.
