摘要
Duringthe mapping of tectonic phases in Shandong Province, the authors found that there are two important Mesozoic collision events in eastern Shandong Province-Indosinian and Yanshannian collision. Indosinian collision orogeny was resulted from the subduction of the Yangtze plate beneath North China Plate, which led to the formation of the Sulu high pressure-ultra-high pressure metamorphic belt, synorogenic granites and post-orogenic high-alkali syenites; the Yanshannian collision orogeny originated from the transformation of central Asia-Tethyan tectonic region to the coastal Pacific tectonic plate, and the subduction of the Pacific Plate, which is demonstrated as three phases of orogeny and extensions in eastern Shandong Province.
