The Late Cretaceous Pınarbaşı Ophiolite (PO), located at central Turkey is represented by distinct rock types (e.g., harzburgite, dunite, pyroxenite, gabbro) that can be observed in many ophiolites around the world. In this study, the classification of rock types of PO in the Eastern Tauride Belt (Turkey) was made using the advanced spaceborne thermal emission and reflection radiometer and Landsat‐8 satellite images. The developed colour–band ratio composite images together with principal component analysis and minimum noise fraction transformations implemented to the remote sensing data efficiently delineate the spatial distribution of pyroxenites, metamorphic sole rocks, and gabbros in the study area. In addition, a body of serpentinized dunites, pyroxenites, metamorphic sole rocks, and listwaenites that has not been recognized before was identified within PO using remote sensing techniques. The promising results of the image processing were verified by detailed field observations and petrographic analysis. The satellite‐based remote sensing approaches of this work can be applicable for mapping ophiolitic rock types in PO in particular as well as other ophiolites from similar geographical regions around the world.

基于ASTER和Landsat-8数据的分析，来自安那托利亚中部（土耳其）的Pnarnaráşı蛇绿岩中的岩石分布

位于土耳其中部的晚白垩世PınarbaşıOphiolite（PO）以独特的岩石类型（例如，哈兹伯格岩，榴辉岩，辉石岩，辉长岩）为代表，可以在世界各地的许多蛇绿岩中观察到。在这项研究中，使用先进的星载热发射和反射辐射计和Landsat-8卫星图像对东陶瑞德带（土耳其）中PO的岩石类型进行了分类。所开发的色带比合成图像以及对遥感数据执行的主成分分析和最小噪声分数转换，可以有效地描绘研究区域中的辉石岩，变质底岩和辉长岩的空间分布。此外，还有蛇纹石化的杜尼尔，辉石岩，变质的岩层，以及以前在PO中使用遥感技术识别的未曾发现的白云母。详细的现场观察和岩石学分析证实了图像处理的有希望的结果。这项工作的基于卫星的遥感方法可适用于绘制PO中的蛇绿岩类型以及来自世界各地类似地理区域的其他蛇绿岩的地图。
