LA-ICP-MS U-Pb geochronology of zircons, whole-rock (main, trace, and REE) geochemistry, and mineral chemistry (feldspars) are constrained for felsic dikes and intermediate volcanic rocks of the Mersin ophiolite in the Inner Tauride Suture Zone (Southern Turkey). The geochronological research, dependent on LA-ICP-MS U-Pb zircon analyses from examined rocks, has yielded a concordia age of 87.38 ± 0.32 Ma for a microgranular felsic dike, stating a Coniacian (Late Cretaceous) age. The felsic dikes show mainly hemicrystalline, aphanitic, porphyritic textures and petrographic analyses from the felsic dikes, and volcanic rocks exhibit that they are mainly dacite, rhyodacite, andesite and basaltic andesite, which are poor in mafic minerals. The mineral chemistry of the dacite and rhyodacite dikes present that plagioclases have a wide range of contents, from andesine (An_31.1–497) to albite (An_03–28.15) and K-feldspars represented by sanidine (Or_42.5–93.3). Dacite/aplite dikes cutting mainly andesitic volcanic rocks present island arc tholeiite-like geochemistry. These felsic intrusive rocks are depleted in HFSE (high-field-strength elements), enriched in LILE (large-ion lithophile elements) and present flat-type REE trends; these patterns furthermore verify their supra-subduction zone geodynamic setting. The initial phase of arc-type volcanics formed above, as can be observed in most of the ophiolites in the Inner Tauride Suture Zone. The arctype volcanics and SSZ-type slab (of metamorphic rock and ophiolite) are cut by dacitic rocks (Coniacian). From the geochronology, field relations, and geochemical evidence from the felsic dikes and volcanics, it can be concluded that the Mersin ophiolite occurred in a tectonic environment (subduction zone) in the southern branch of the Neo-Tethys, located in modern Southern Anatolia.

LA-ICP-MS锆石的U-Pb年代学，全岩（主，痕量和REE）地球化学和矿物化学（长石）被限制在Tauride内缝合带的Mersin蛇绿岩的长堤和中火山岩中（土耳其南部）。地质年代学研究依赖于对所检查岩石的LA-ICP-MS U-Pb锆石分析，得出微细粒长颈堤的共生年龄为87.38±0.32 Ma，表明柯尼西亚（白垩纪晚期）年龄。长笛岩岩脉主要表现为半晶质，甲壳岩，斑岩质和长岩岩脉的岩石学分析，而火山岩则以辉长岩，菱锰矿，安山岩和玄武质安山岩为主，镁铁质矿物含量较低。闪锌矿和流纹岩堤防的矿物化学表明，斜长石具有广泛的含量，_31.1–497）至钠长石（An _03–28.15）和以山定素代表的钾长石（或_42.5–93.3）。主要切割安山岩火山岩的达克特/磷灰石堤防呈现出岛弧状的似孔雀石的地球化学特征。这些长英质侵入岩中的HFSE（高场强元素）贫乏，而LILE（大离子的嗜石元素）富集，呈现出扁平型REE趋势。这些模式进一步验证了它们的超俯冲带地球动力学环境。上面形成的弧型火山的初始阶段，在内陶瑞德缝合带的大多数蛇绿岩中都可以观察到。弧形火山岩和SSZ型板岩（变质岩和蛇绿岩）被大山岩（Coniacian）切割。从地球年代学，田间关系以及从长石堤和火山的地球化学证据来看，可以得出结论：梅尔辛蛇绿岩发生在新特提斯南部分支的构造环境（俯冲带）中，
