Felsic tuff as a direct fallout deposit is known from one small area in the Kyrenia Range, north Cyprus, within deep-sea terrigenous turbidites. Nearby tuffaceous siltstones contain compositionally similar felsic volcanic rocks (c. 5–10%), mixed with terrigenous material. Sedimentary evidence indicates that the fallout tuff was variable reworked locally, whereas the tuffaceous siltstones are interpreted as turbidites mixed with terrigenous material derived from Anatolia. U–Pb dating of zircons that were extracted from a sample of relatively homogeneous tuff yielded a dominant age of 16.64 ± 0.12 Ma (Burdigalian). Zircon trace-element analysis indicates predominant derivation from within-plate-type felsic magma. Whole-rock chemical analysis of the tuffaceous sediments as a whole is compatible with a felsic arc source, similar to the post-collisional magmatism within Anatolia. Regional comparisons suggest that the nearest volcanism of similar age and composition is located c. 500 km away, within the Kırka area (Eskişehir region) of the Western Anatolia Volcanic Province. Evidence of tephra dispersal in the western Mediterranean region and climatic modelling suggests E-wards prevailing winds and therefore tephra transport over southern Anatolia and adjacent areas during early Miocene time. The north Cyprus tuffs could represent powerful Minoan (Plinian)-type eruptions in western Anatolia, coupled with SE-wards tephra transport during and soon after the onset of post-collisional magmatism.

早中新世钙碱性长英质凝灰岩位于塞浦路斯北部凯里尼亚山脉的深海浊积岩中，可能在安纳托利亚西部有一个碰撞后喷发中心

长英质凝灰岩是一种直接沉降沉积物，位于塞浦路斯北部凯里尼亚山脉的一个小区域，位于深海陆源浊积岩中。附近的凝灰质粉砂岩含有成分相似的长英质火山岩（C。5–10%)，与陆源物质混合。沉积证据表明，沉降凝灰岩在局部进行了可变改造，而凝灰质粉砂岩被解释为混有来自安纳托利亚的陆源物质的浊积岩。从相对均质凝灰岩样品中提取的锆石 U-Pb 测年产生的主要年龄为 16.64 ± 0.12 Ma（Burdigalian）。锆石微量元素分析表明主要来源于板内型长英质岩浆。整个凝灰质沉积物的全岩化学分析与长英质弧源相容，类似于安纳托利亚内的碰撞后岩浆作用。区域比较表明，最近的具有相似年龄和成分的火山位于C。500 公里外，位于安纳托利亚西部火山省的克尔卡地区（埃斯基谢希尔地区）。西地中海地区的火山灰散布证据和气候模型表明，在中新世早期，盛行东风，因此火山灰在安纳托利亚南部和邻近地区的运输。北塞浦路斯凝灰岩可能代表安纳托利亚西部强大的米诺斯（普林尼）型喷发，以及在碰撞后岩浆作用开始期间和之后不久的东南向火山灰输送。
