The Kashafrud Basin (NE Iran) during the Jurassic: A key for understanding the post-collisional history of the Iran Plate

伊朗东北部的Koppeh Dagh山脉和Binalud山脉之间的边界对应于古提斯纪的缝合线，古提斯纪是一个海洋，在今天的伊朗地区，在三叠纪末期已经完全俯冲到北部的图兰板块之下。在作为欧亚大陆的一部分的图兰板块和作为所谓的西米里亚微大陆拼合的一部分的伊朗板块之间的边界上，形成了一个强烈的沉降盆地，形成于中侏罗世，它被厚厚的（高达2000米）沉积物堆填满，从河流到深海浊积物（Kashafrud组）。研究的目的是在综合地层学、沉积学、技术和古生态调查的基础上，重建盆地的沉积环境及其时空格局。结合物源和沉降分析，这些综合数据将阐明Kashafrud盆地的起源、类型、演化和地球动力学背景。预期的结果将大大提高我们对伊朗板块与欧亚大陆碰撞后影响其复杂地质事件的理解。

The boundary between the Koppeh Dagh and the Binalud Mountains in northeastern Iran corresponds to the suture of the Palaeothethys, an ocean which, in the area of present-day Iran, had been completely subducted below the Turan Plate in the north towards the end of the Triassic. At this boundary between the Turan Plate as part of Eurasia and the Iran Plate as part of the so-called Cimmerian Microcontinent Collage, a strongly subsiding basin formed during the Middle Jurassic, which became infilled with a thick (up to 2,000 m) pile of sediments, ranging from fluvial to deep-marine turbidites (Kashafrud Formation). Aim of the study is the reconstruction of the depositional environments of the basin and of their temporal-spatial pattern based on integrated stratigraphic, sedimentological, ichnological and palaeoecological investigatons. Combined with a provenance and subsidence analysis these integrated data will elucidate the origin, type, evolution, and geodynamic context of the Kashafrud Basin. The expected results will significantly enhance our understanding of the complex geological events that affected the Iran Plate after its collision with Eurasia.
