The new data reveal three units of rocks formed at different stages of the Akitkan orogen evolution. Unit 1 includes mainly leucocratic gneisses derived from 2.7–2.5 Ga polymictic sandstones or graywackes. These sediments were deposited upon the basement of the Sarma terrane composed of 2.88 Ga TTG granitoids that became the source of clastic material. Unit 2 consists of quartzite and schists produced by metamorphism of quartz and polymictic sandstones and siltstones. Judging by the ages of detrital zircons from mica-quartz schists, along with the age of metamorphism, the deposition of the sedimentary protoliths lasted from 2.15 to 1.95 Ga. It was maintained by destruction of felsic rocks within the Sarma terrane prior to the collisional event that led to the formation of the Akitkan orogen. Unit 3 likewise includes quartzites and schists but those derived from more mature sediments. The clastic material predominantly originated from 1.88–1.84 Ga rocks of the South Siberian magmatic belt and was deposited in intracontinental basins between 1.00 and 0.72 Ga, after the assembly of the Siberian craton.

Our results reveal two Holocene earthquakes, corresponding to the E2 and E3 events identified in previous studies along the Mondy, Tunka, and Main Sayan faults. These three faults have been interpreted as having produced seismic clusters at least four times in the Late Pleistocene-Holocene times. Our radiocarbon data allow constraining more tightly the ages of the E2 and E3 events to 3170–3399 and 8453–8540 cal yr BP, respectively.

In this study, we integrate sedimentological, structural, geophysical, and thermochronological approaches to examine the Jurassic tectonic activity of the eastern segment of the ATF. Analyses of soft-sediment deformation structures indicate that the Altyn Tagh Range experienced incipient, submarine uplift without the development of significant surface topography. The recognition of Jurassic stratigraphic contacts and flower structures in seismic profiles further suggests localized uplift and strike-slip deformation. Detrital zircon U-Pb age spectra exhibit near-source signatures, implying restricted lateral displacement along the fault during the Jurassic. Moreover, aeromagnetic anomaly interpretation combined with low-temperature thermochronology indicates that the ATF operated within a dynamic framework involving pre-Jurassic southward deep subduction of the Tarim Block and northward shallow subduction of the Qaidam Block, mediated by a deep lithosphere-mantle ductile shear zone. Under this tectonic configuration, the fault experienced limited strike-slip motion, segmented activity, and localized uplift during the Jurassic.</div></div>","PeriodicalId":50253,"journal":{"name":"Journal of Asian Earth Sciences","volume":"297 ","pages":"Article 106899"},"PeriodicalIF":2.4,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145749809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the mineralogical, sedimentological, and geochemical characteristics of thick bedded dolostones of the Ordovician Majiagou Formation (Member 5) in the eastern Ordos Basin, China. These dolostones consist of stacked meter to submeter scale thin bedded cycles, characterized by three key facies: cryptocrystalline dolostone with spherical gypsum molds, microcrystalline dolostone with nonplanar crystal boundaries and lath shaped gypsum pseudomorphs, and fine crystalline dolostone with planar boundaries lacking gypsum. The vertical distribution of these facies correlates with sea level cyclicity and geochemical variations in dolomite stoichiometry, indicating that dolomitization was controlled by high frequency sea level oscillations. The preservation of horizontal gypsum pseudomorphs, together with diagnostic Th/U ratios and bell-shaped REE patterns, supports a low energy, restricted cratonic setting. We apply a syndepositional model wherein evaporative concentration in a warm, shallow greenhouse sea led to calcite and gypsum precipitation, elevating the Mg/Ca ratio and triggering dolomitization. The resulting dense brine percolated downward, replacing unconsolidated calcareous precursors to form the observed dolostone types. This case demonstrates that high frequency sea level oscillations and their resultant thin bedded cycle stacking can constitute an efficient formation mechanism for thick bedded dolostones in cratonic basins.</div></div>","PeriodicalId":50253,"journal":{"name":"Journal of Asian Earth Sciences","volume":"297 ","pages":"Article 106889"},"PeriodicalIF":2.4,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145694598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The platy Mag1 is mushketovite, replacing early hematite. The granular Mag2, with well-defined 120° triple junction textures, formed through fluid-assisted recrystallization processes. Mag1 has a trace element composition very similar to the precursor hematite, indicating that the trace element characteristics of Mag1 were inherited from hematite and do not reflect the trace element composition of the fluid at the time of its formation. Mag2 has higher contents of Ti, V, Al, Mg, Si, Mn, Co and Ni, reflecting the trace element characteristics of the fluid in equilibrium with Mag2 during its formation. The early precipitation of magnetite and hematite can effectively inhibit the premature incorporation of Co into sulfides, thereby promoting pre-enrichment of Co in the fluid. While the precipitation of magnetite and hematite can increase the Co/Fe ratio in the residual fluid, it does not directly cause the high Co enrichment in sulfides within the Jinchang deposit.
