摘　　要：The Devonian stratigraphy and tectonic evolution of the Karamaili collision zone is poorly studied. According to Late The Devonian Keankudouke Formation consists of coarse clastic deposits with Prelepidodendron fossils, poorly sorted and poorly rounded gravels, gravel rhythmic structures with carbonaceous mudstones, conglomerate rhythmic structures, and thick conglomerates. These deposits are interpreted as molasses, indicating that tectonic collision occurred in the Late Devonian, rather than in the Carboniferous as previously thought.
