The Baluti Formation is a lithostratigraphic unit defined at outcrop in the Zagros foldbelt in Kurdistan, North Iraq, where it consists of a thin, shale‐dominated interval between the thick carbonates of the overlying Sarki and the underlying Kurra Chine Formations. New biostratigraphic results presented in this study confirm that firstly, the Baluti shale marks the top of the Carnian at outcrop; and secondly, that the correlative subsurface shale occurs well above the base of the subsurface‐defined Butmah Formation. As such, the Butmah is not directly correlative to the Sarki as has previously been assumed, and its definition overlaps that of the Baluti and Kurra Chine Formations.

伊拉克库尔德斯坦，巴尔迪地层的年代和相关性：对一个区域性认识的“卡纳”“标志白云岩”意义，以及对阿拉伯板块三叠纪至早侏罗纪层序地层的回顾

Baluti地层是一个岩石地层单元，定义在伊拉克北部库尔德斯坦Zagros褶皱带的露头处，它由上覆的Sarki厚碳酸盐岩与下伏的Kurra Chine地层之间的页岩为主的薄层间隔组成。这项研究提出的新的生物地层结果证实，首先，Baluti页岩在露头处标明了Carnian的顶部。其次，相关的地下页岩发生在地下定义的Butmah地层底部之上。因此，Butmah与先前所假设的Sarki不直接相关，其定义与Baluti和Kurra Chine地层的定义重叠。
