This work presents a catalog of the products of the Cenozoic volcanism on mainland Asia, exclusive of the Koryak and Kamchatka Peninsulas. A synthesis of the available information illustrates that the dominant volcanic landforms are fissures and cinder cones. Some large composite volcanoes are found in Burma, western China, and the northeastern Soviet Union. Peaks of volcanic activity took place during Oligocene-Miocene and Pliocene-Pleistocene time. There is historic evidence for the eruption of fewer than 20 volcanoes; however, many volcanoes occur in isolated, uninhabited regions. In general, with increasing distance from the plate boundaries, there is an increase in alkalinity of the volcanic products, and a tendency for increasing alkalinity with decreasing age. A very small proportion of the rocks plot within the subalkalic field. The principal tectonic controls on volcanism were the early Cenozoic subduction along the eastern seaboard, the collision of the Indian continent, the development of back-arc basins, and interactions between the Asian and North American plates.
