9317100 Whitney This research planning grant seeks to document the metamorphic history of two massifs (Kirsehir, Nigde) within the Central Anatolian Massif in Turkey. These metamorphic massifs have been interpreted as continental fragments rifted from Afro-Arabia, and currently they occupy a key tectonic position surrounded by suture zones in the Tethyan domain. Preliminary research will focus on (1) describing mineral assemblages in progressive metamorphic facies, (2) documenting mineral paragenesis and PTt paths using compositional information and reaction textures, (3) evaluating the physical conditions of metamorphism and emplacement of the massifs, and (4) determining how further study of these rocks might contribute to ongoing discussions of the role of metamorphic fluids in amphibolite-to- granulite transitions and ultrametamorphism. Planning activities will include both field and analytical work (mineral, whole-rock analysis, isotopic dating).

9317100 Whitney这项研究计划资助旨在记录土耳其安纳托利亚中部地块内两个盆地（Kirsehir，Nigde）的变质历史。 这些变质碎屑岩被解释为从非洲-阿拉伯大陆断裂的大陆碎片，目前它们在特提斯域中占据了缝合带所包围的关键构造位置。 初步研究将集中在（1）描述渐进变质相的矿物组合，（2）利用成分信息和反应结构记录矿物共生和PTt路径，（3）评价变质作用和侵位的物理条件，以及（4）确定对这些岩石的进一步研究如何有助于正在进行的关于变质流体在角闪岩-麻粒岩转变和超变质作用中的作用的讨论。 规划活动将包括实地和分析工作（矿物、全岩分析、同位素测年）。
