Late Triassic rifting and Jurassic–Cretaceous passive margin development of the Southern Neotethys: evidence from the Adıyaman area, SE Turkey

摘要: Evidence of rifting and continental break-up to form the S Neotethys is found within volcanic-sedimentary Kocali Complex. This a folded, thrust-imbricated succession that includes lavas, volcaniclastic sediments, pelagic carbonates, radiolarites manganiferous deposits. Interbedded ribbon cherts contain radiolarians Late Triassic Jurassic age. The lower part Mid?-Late age (Tarasa Formation) dominated by enriched mid-ocean ridge basalt (E-MORB). overlying Mid-Jurassic interval (Konak characterised intercalations ocean island E-MORB. Taking account structural position, basalts erupted outer continent–ocean transition zone. Continental probably occurred during (Carnian–Norian). Early lavas sediments record volcanism after break-up. In addition, Karadut Complex broken formation located at relatively low position just above Arabian foreland. Pelagic redeposited carbonates predominate. Radiolarians are dated as Cretaceous in include planktic foraminifera resulted from accumulation calcareous gravity flows, carbonate proximal, base-of-slope setting. After break-up, MORB ophiolitic rocks formed further north. Tectonic emplacement onto platform took place earliest Maastrichtian time. Regional interpretation facilitated comparisons with examples eastern Mediterranean region elsewhere.
