title: Geochemical signature, detrital zircon U–Pb, and mica Ar–Ar age systematics from the Karadere Basement Unit of the İstanbul-Zonguldak Terrane (NW, Türkiye): evidence for an Avalonian-Cadomian active continental margin

description: The İstanbul-Zonguldak Terrane is located in northwest Anatolia and includes several outcrops with pre-Cambrian basement units. The Karadere Basement Unit represents the easternmost basement of this terrane and is composed of paragneiss, quartzite, and orthogneiss. The paragneiss and quartzite are cut by orthogneisses and disconformably overlain by Lower Ordovician to Middle Devonian cover units. Its pre-Cambrian to Palaeozoic tectonic evolution remains poorly understood, and therefore, this study reports whole-rock trace element signatures, detrital zircon U–Pb, and muscovite Ar–Ar age data for samples of paragneiss, quartzite, amphibolite, and orthogneiss. The whole-rock geochemical data indicate that the protoliths of the paragneiss and quartzite samples investigated here could have been derived from arc-related felsic magmatic units located in an active continental margin. The protoliths of amphibolites and orthogneiss samples are gabbro and granite, respectively, and their geochemical signatures are akin to those from continental arc igneous suites. The detrital zircon U–Pb data are characterized by predominantly Mesoproterozoic (84%) and lesser amount of Palaeoproterozoic and Neoproterozoic ages and suggest an early Tonian (youngest peak age of 915 ± 18 Ma) maximum depositional age. Moreover, zircon U–Pb dating analyses from an orthogneiss sample yielded an age of 603 ± 2 Ma, indicating the occurrence of mid-Ediacaran arc magmatism. This represents one of the oldest Ediacaran ages obtained from the metamagmatic basement rocks of the İstanbul-Zonguldak Terrane. Ar–Ar dating of muscovite from ortho- and paragneiss samples yielded ages of 533 ± 25 Ma and 530 ± 9 Ma, respectively, which are interpreted as early Cambrian cooling ages. Overall, the combined results reported here reveal that the Karadere Basement Unit is markedly different from NE African basement units but displays similarities to the basement rocks of both Avalonian and Amazonian terranes. It may have been formed and metamorphosed in an Avalonian–Cadomian active continental margin during the mid- to late Neoproterozoic and early Cambrian.

title: Episodic metamorphism of the central Gondwana revealed by zirconology of pegmatites and regional granulites from Sri Lanka and its peripheral terranes

description: Reconstructing ancient continents hinges on deciphering polymetamorphic records. Here, we integrate new U–Pb zircon ages with <i>pressure–temperature–time–deformation (P–T–t–D)</i> constraints to resolve the late Cryogenian–Ordovician evolution of the Highland Complex (HC), Sri Lanka (~660–460 Ma). Our results reveal a reworked crust comprising Palaeoarchean to Neoproterozoic (&gt;700 Ma) sedimentary sequences and magmatic additions at ~2500 Ma, 2000–1650 Ma, 1050–810 Ma, 730–670 Ma, 620–570 Ma, 560–520 Ma, and ~490–460 Ma, with possible ~1800 Ma metamorphism. Four episodic metamorphic phases (MP1–MP4) overprinted these lithologies during Gondwana amalgamation. MP1 (~660–640 Ma) reflects early prograde metamorphism during crustal thickening. MP2 (~630–550 Ma), peaking at 590–570 Ma and followed by near-isobaric cooling (570–550 Ma), records high-temperature metamorphism during major collision. MP3 (~550–510 Ma) marks retrograde metamorphism, deep crustal exhumation (~550–545 Ma), and subsequent extension (545–510 Ma). MP4 (~490–460 Ma) represents a later thermal overprint, likely linked to post-collisional extension. These events correlate with the East African (MP1), Kirwan (MP2), and Kuunga (MP3), while the responsible tectonothermal event for MP4 is not confirmed. Pegmatitic intrusions dated at 560–550 Ma, 550–510 Ma, and 490–460 Ma capture late- to post-orogenic reworking. The temporal and thermal alignment of MP1–MP4 with metamorphic histories in the Trivandrum Block (southern India) and Lützow–Holm Complex (East Antarctica) supports their interpretation as once-contiguous fragments of central Gondwana. This integrated study refines the tectonometamorphic framework of the HC and highlights its significance in reconstructing crustal architecture shaped by the formation of central Gondwana.
