Kitakami Mountains

Kitakami Mountains (Kitakami sanchi) is a mountain range in northeastern Honshu, in the Tōhoku region of northern Japan. The range extends for 250 kilometres (160 mi) from the southern border of Aomori Prefecture in the north to the northern border of Miyagi Prefecture in the south, and are bordered by the Kitakami River valley in the west and the Pacific Ocean to the east, with an average width of around 80 kilometres (50 mi).The Kitakami Mountains are thus mostly located within eastern Iwate Prefecture. The range is largely an eroded plateau with a thick granite bedrock, thus accounting for its other name: Kitakami Plateau (Kitakami-kōchi). In the north, the mountains are characterized by marine terraces at an altitude of around 300 meters, whereas in the south, the mountains are drowned to form a deeply indented rias coast. Geologically, the Kitakami Mountains are Paleozoic and Mesozoic formations, divided into northern and southern groups. the southern area has oldest previous Silurian foundation, which was once a shallow sea on the continental margin where the water temperature was high enough for coral growth from the Silurian to the Devonian periods; this region, later collided with the northern Kitakami mountainous area in the early Cretaceous period, and the whole was penetrated by the granite in various places. Until the Paleogene, the Kitakami Mountains were geologically part of Primorsky region of Siberia. About 30 million years to 15 million years ag
