Study on the Orogenic Type Gold Deposits in Eastern Shandong Province
详细信息   
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.
