Cekungan sedimen Kutai membentang dari dataran tinggi bagian tengah Kalimantan, melintasi pantai timur pulau ini dan menuju Selat Makassar. Dengan luas 60.000 km2, dan kedalaman hingga 1515 km, Cekungan Kutai merupakan cekungan usia Tersier terbesar dan terdalam di Indonesia.[1] Evolusi [tektonika lemepng]] dalam wilayah Indonesia Asia Tenggara telah menghasilkan berbagai formasi cekungan di Cenozoic.[2] The Kutai is an extensional basin in a general foreland setting. Its geologic evolution begins in the mid Eocene and involves phases of extension and rifting, thermal sag, and isostatic subsidence. Rapid, high volume, sedimentation related to uplift and inversion began in the Early Miocene.[1] The different stages of Kutai basin evolution can be roughly correlated to regional and local tectonic events.[2] It is also likely that regional climate, namely the onset of the equatorial ever wet monsoon in early Miocene, has affected the geologic evolution of Borneo and the Kutai basin through the present day.[3]
