In this study, we comprehensively assessed the organic matter abundance, type, maturity, and trace element characteristics of oil shale by collecting and analyzing oil shale samples from the Lower Permian region in the western part of the southern margin of the Junggar Basin, and by applying pyrolysis analysis and rock pyrolysis analysis. The study showed that the average value of total organic carbon (TOC) of the oil shale in the study area was 10.26%, of which 41.67% was medium-grade oil shale and 58.33% was low-grade oil shale, reflecting the overall abundance of medium-low organic matter. The average value of hydrocarbon potential was 40.83 mg/g. The hydrogen index of the oil shale samples ranged from 77 to 861.06 mg/g, with an average value of 405.56 mg/g. The organic matter type was mainly of the II₁ type (humic-sapropelic type), which accounted for 75% of the total, and the analysis of the highest pyrolysis peak temperature showed that 83.33% of the samples were in the low maturity-mature stage. Trace element analyses revealed that the oil shales in the study area were formed in a terrestrialweakly reduced depositional environment. Especially, the analysis of Sr/Ba, Th/U and B/Ga ratios indicated that the oil shale was mainly formed in freshwater-semi-saline environment. In addition, the analysis of V/(V+Ni) and U/Th ratios supports the reduced environment in which the oil shale was formed. The shale in the Dalongkou area has greater salinity values and higher organic matter productivity in the water body at the time of formation compared to the oil shale in the Cangfanggou area. The results of this study are important for understanding the geochemical properties and mineralization potential of the Lower Permian oil shales in the western part of the southern margin of the Junggar Basin.</p>","PeriodicalId":9908,"journal":{"name":"Chemistry and Technology of Fuels and Oils","volume":"21 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141741904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carotid revascularization techniques [carotid endarterectomy (CEA) and carotid artery stenting (CAS)] may benefit cognition, though there are opposing findings, reporting an apparent decrement in cognitive function, no effect, or an apparent improvement after revascularization. A great number of studies are trying to evaluate the effect of carotid revascularization (CEA, CAS) on patients' cognitive functions, as well as on their psychological condition and quality of life through a baseline and follow-up neuropsychological examination. Recent reviews refer only to the narrow limits of cognitive deficits that may be attributed to carotid stenosis, rather than elucidating the outfit of all aspects of mental and cognitive correlations. Most of those findings depict controversy in current literature as far as the neuropsychological effects of carotid revascularization techniques are concerned, while clinical entities of \"vascular dementia\" and \"vascular depression\", as well as intercurrent vascular risk factors are also addressed. This might be taken into consideration, when determining the optimal therapeutic strategy for tackling carotid artery occlusive disease, while best practice clinical decisions should be still focused on stroke prevention and symptoms alleviation, until further research on the field of neuroangiology presents undisputable conclusions regarding the underlying effects of revascularization on mood and cognition.

The progradational reflection seismic facies can be divided into two types: S-shaped and oblique progradational reflection facies. The oblique progradational reflection seismic facies representing the rapid filling environment of sediments are mainly distributed in the southeast of the study area, while the northwest mainly develops relatively low-energy sedimentary mechanisms of S-shaped seismic facies. The incised valley seismic facies are mainly distributed in the eastern and southeastern parts of the work area. On the plane, the incised valley seismic facies have a trend of gradually widening and shallowing towards the northwest direction. In addition, the distribution of sedimentary facies was analyzed using seismic attributes. The southeastern and central parts of the study area are mainly composed of proximal sand-rich braided river alluvial plains, while the northwestern part is mainly composed of distal mud-rich braided river alluvial plains.

The method in which CO₂ is stored depends on its phase state and the depth at which it is injected. In this study, the fault-reservoir system is constructed to elucidate the fault leakage behaviors and CO₂ migration in different geological storage environments. Whether CO₂ is buoyant or sinking depends on the fluid density difference between CO₂ and H₂O. When carbon dioxide is injected into deep saline aquifer, CO₂ would preferentially migrate upward along the fault plane due to CO₂ buoyancy forces, and CO₂ plume accumulates beneath the caprock and floats at the top of the reservoir eventually. For CO₂ storage in deep ocean reservoir and volcanic basalt, no upward migration of CO₂ plume is observed during carbon storage. Fault plane is the preferential pathway for carbon downward transportation during ocean-based CO₂ storage, providing a virtually unlimited environment. Compared with deep ocean storage, the much shorter sinking times makes volcanic basalt for carbon storage safer and more effective. It is illustrated that the fluid density difference between CO₂ and H₂O is the decisive factor in determining CO₂ sinking velocity.
