“…Generally, Ordovician to Early-Middle Devonian magmatic activities in different parts of Iran are interpreted as rift-related magmatic events that led to the formation of the Paleotethys Ocean (e.g., Jenny, 1977;Stampfli, 1978;Berberian and King, 1981;Boulin, 1991;Stampfli et al, 1991;Alavi, 1996;Lasemi, 2001; Ghasemi and Derakhshi, 2008;Bagheri and Stampfli, 2008;Ghasemi, 2014, 2015;Ayati, 2015;Hosseini et al, 2015). Also, study of Paleozoic ophiolites of Iran by Shafaii Moghadam and Stern (2014) indicates that all of them are remnants of Paleotethys Ocean and have a range of ages from Devonian to Permian.…”

Geochemistry and petrogenesis of Soltan Maidan basalts (E Alborz, Iran): Implications for asthenosphere-lithosphere interaction and rifting along the N margin of Gondwana

Soltan Maidan Basaltic Complex with thickness up to about 1300 m is located in the eastern Alborz zone, north of Iran. This complex is dominantly composed of transitional to mildly alkaline basaltic lava flows, agglomerates and tuffs, together with a few thin sedimentary interlayers. Field geological evidence and study of palynomorph assemblages in the shale interlayer show Late Ordovician to Early Late Silurian ages. Chondrite-and primitive-mantle normalized multi-element patterns of Soltan Maidan basalts demonstrate enrichment in highly incompatible elements relative to less incompatible ones and their patterns are most similar to

“…The subsequent passive margin sequence would comprise a more or less continuous carbonate platform development until the Mid Triassic when the margin was involved in the Eocimmerian tectonic cycle (Meinhold et al, 2020). Similar Silurian-Carboniferous rift-related events have been suggested throughout the so-called Turkish-Iranian-Afghan segment of Gondwana, changing subsequently into passive-margin conditions and the final opening of the Palaeotethys Ocean (e.g., Berberian and King, 1981;Stampfli et al, 1991;Lasemi, 2001;Bagheri and Stampfli, 2008;Ghasemi and Derakhshi, 2008;Bagheri and Stampfli, 2008;Ghasemi, 2014, 2015;Hosseini et al, 2015).…”

“…However, the evolution of the Proto-Tethys Ocean along the northern margin of the entire Gondwana is different. A large number of rock formations related to the subduction of the Proto-Tethys Ocean have been found along the northern margin of the West Gondwana, such as 576-536 Ma granitic rocks and 579-536 Ma metabasic rocks in Kuh-e-Sarhangi area, central Iran (Rossetti et al 2015;Hosseini et al 2015) (Vermeesch, 2013). The MDS plot based on the Kolmogorov-Smirnov (K-S) statistical method (Fig.…”

During the existence of Proto-Tethys Ocean (550–430 Ma), microcontinents in northern East Gondwana merged with the northern margin of India-Australia, completing the assembly of Gondwana. Ongoing controversy surrounds the disappearance of the Proto-Tethys Ocean, the dynamic mechanisms of suturing and the palaeogeographic relationships among microcontinents in northern East Gondwana, contributing to the uncertainty about the tectonic evolution of the region. This paper concerns the lower Silurian Zusailing Formation in the Hainan Island and focuses on the affinity between Hainan Island and various microcontinents in northern East Gondwana during the early Silurian. We use detrital zircon geochronology to reconstruct the closure process of the Proto-Tethys Ocean and show that the detrital zircon U–Pb age groups of the lower Silurian Zusailing Formation are 2800–2200, 2100–1350, 1250–950, 600–480 and 480–430 Ma, with a significant age peak of ca. 449 Ma. Furthermore, the analysis of detrital zircon geochemistry and europium anomalies shows that the Hainan Island crust continued to thicken during 600–434 Ma. Comparing the age spectrum of early Palaeozoic detrital zircons from Hainan Island and various microcontinents in northern East Gondwana, as well as the affinity among them during the Silurian, we conclude that the closure of the eastern Proto-Tethys Ocean evolved from unidirectional subduction (600–480 Ma) to bidirectional subduction (480–430 Ma).
