Cekungan Kutai
Cekungan sedimen Kutai membentang dari dataran tinggi bagian tengah Kalimantan, melintasi pantai timur pulau ini dan menuju Selat Makassar. With an area of 60,000 km2, and depths up to 15 km, the Kutai is the largest and deepest Tertiary age basin in Indonesia.[1] Plate tectonic evolution in the Indonesian region of SE Asia has produced a diverse array of basins in the 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]
