The oldest strata in Kanbula Geopark are the Paleo-Mesoproterozoic Hualong Group metamorphic rocks, which are overlain by the Paleozoic Permian marine strata, with Changcheng System and Devonian System missing in the middle, and the sedimentary hiatus is nearly 1.5 billion years.  Kanbula Geopark is typically characterized by the Triassic strata, of which the Middle and Lower Triassic are marine strata, while the Upper Triassic is continental volcanic sediment, which records the closure of the Paleo-Tethys Ocean in the West Qinling and South Qilian Orogenic Belt of China caused by the Indosinian movement.  The Jurassic strata are influenced by the Yanshan movement, and only the volcanic sediment of the Middle Jurassic is preserved; the Cretaceous strata are relatively complete, but the Upper and Lower Cretaceous strata, influenced by the Late Yanshan movement at the end of the Early Cretaceous, show angular unconformity contact.  The Paleogene strata are affected by the Himalayan orogeny, and only the Xining Group are exposed.  The Neogene to Quaternary strata are relatively well exposed.
