This article presents a pioneering tectono-stratigraphic examination of Miocene Formations in the Fars and Bandar Abbas Hinterland, Southern Iran. The study meticulously explores five locations—Bastak, Taghdis-e Bahar, Dasht-e Arzhan, Saedi Mountain, and Yasuj—analyzing stratigraphic sections of the Miocene Formation. The Isopach map exposes variations in Miocene Formation thicknesses across these sites. In the Arjan plain, significant facies change unfolds, transitioning from Gachsaran Formation’s evaporitic sedimentary rocks to Rzak Formation’s marine sedimentary rocks and Asmari Formation’s calcareous rocks along a northwest–southwest border. These facies change correlates intricately with subtle movements of fault zones—Kareh–Bas, Sabzpooshan, Sarvestan, and Kazerun. The tectono-stratigraphic journey unveils a profound connection between changes in sedimentary basin depth and nuanced alterations in sedimentary rocks’ facies, orchestrated by the interplay of various basement faults, some following the Arabian trend, others aligning with the majestic Zagros trend—a symphony of geological forces shaping the Miocene narrative in the Fars and Bandar Abbas Hinterland.</p>","PeriodicalId":11352,"journal":{"name":"Doklady Earth Sciences","volume":"56 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper combines TerraSAR-X and RADARSAT-2 heterogeneous SAR images employing MSBAS technology to obtain the three-dimensional time-series of deformation of the 132 610 working face in the Fengfeng mine from December 2015 to February 2016. The monitoring results show that the maximum surface subsidence and the subsidence rate during the monitoring period were –243 mm and 4.42 mm/day, and the maximum east-west horizontal movement was –80~30 mm. The surface subsidence basin is in the active stage, which is prone to pose a threat to the safety of the surrounding structures. Comparison with the leveling data shows that the root-mean-square deviation of the vertical deformation obtained by MSBAS technology is 10.7 mm, and the accuracy can reach the centimeter level. Meanwhile, based on the vertical deformation obtained by MSBAS technology, combined with the proportionality relationship between horizontal movement and tilt, the north-south horizontal movement was estimated as –80~70 mm, which provided a solution for obtaining the north-south horizontal movement of the mining area by InSAR. Analysis of the three-dimensional time-series of the surface deformation at the main sections shows that the surface deformation features during the mining process of the 132610 working face match well with the general model of mining subsidence, but the working face inclination angle has an influence on the surface deformation.</p>","PeriodicalId":11352,"journal":{"name":"Doklady Earth Sciences","volume":"6 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together with the other Au, W, and Cu deposits and occurrences, they are parts of the extended metallogenic belt of Tien Shan. The concordant isotopic U–Pb age data for zircon autocrysts from the rocks of the consecutive intrusive phases span over the interval of approximately 325 to 302 Ma. This interval comprised the crystallization of monzogabbro (321 ± 4 Ma), monzonite (319 ± 4 Ma), camptonite (306 ± 4 Ma), syenite (307 ± 6 Ma), quartz syenite (305.5 ± 2 Ma), and quartz monzonite (305 ± 3 Ma). Zircon antecrysts dated at 316–325 Ma to 335–345 Ma have also been identified. The age data obtained are consistent with the age of subduction processes defined for the western part of the Middle Tien Shan. However, both geochemical characteristics of the rocks from the Kensu pluton and a distinct W–Mo mineralization related to this pluton contradict the subduction-related setting of the pluton emplacement but, instead, point out the post-collisional setting of the intrusion emplacement. This discrepancy can be explained by a “scissor-like” (from east to west) closure of the Turkestan paleoocean that has resulted in the post-collisional regime in the eastern part of the “Nikolaev Line,” whereas subduction continued in its western part. The rocks also contain zircon xenocrysts with a much older age (in to order of 1.9 Gb) that probably represents the age of the Tarim craton basement rocks; this indicates an involvement of the ancient material in the magma generation. </p>","PeriodicalId":11352,"journal":{"name":"Doklady Earth Sciences","volume":"73 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
