Abstract The Karadag stratovolcano (KS), located at the southern end of the Cappadocian Volcanic Province in Central Anatolia, Turkey, is a key volcanic vent for understanding the spatiotemporal association between adakitic and mafic potassic (absarokitic-shoshonitic-banakitic) magmas in a post-subduction intracontinental setting. Here, we present a comprehensive geochemical dataset consisting of mineral chemistry, major and trace elements, Sr–Nd–Pb isotopes and conventional K-Ar age data for the adakitic andesite-dacite series of the KS. KS was built up by the eruption of adakitic andesites (825 ± 17 ka), absarokite-shoshonites (393 ± 153 ka), adakitic dacites (45 ± 6 ka) and effusive deposits (

沉积物衍生的熔体相关交代地幔楔作为与来自 Karadağ 成层火山(Karaman,安纳托利亚中部,土耳其)的 absarokite-shoshonite 相关的第四纪埃达克质斑岩的来源

摘要 卡拉达格成层火山 (KS) 位于土耳其安纳托利亚中部卡帕多奇亚火山省的南端,是了解埃达克质和镁铁质钾质 (absarokitic-shoshonitic-banakitic) 岩浆时空联系的关键火山口。 -俯冲大陆内环境。在这里,我们提供了一个全面的地球化学数据集,包括 KS 埃达克安山英安岩系列的矿物化学、主要和微量元素、Sr-Nd-Pb 同位素和常规 K-Ar 年龄数据。KS 是由埃达克安山岩 (825 ± 17 ka)、absarokite-shoshonites (393 ± 153 ka)、埃达克英安岩 (45 ± 6 ka) 和喷发沉积物 (
