The juncture between the Yangtze Paleoplate and the Cathaysian Paleoplate extends from Qinzhou Bay to Hangzhou Bay, called "Qinzhou-Hangzhou juncture" for short. During the Sibao-Caledonian time the juncture became a compound collision melange belt; in the Mesozoic era it became source of Yanshanian movement in southern China, with intense compression. It has become one of the most important magmatic-metallogenic belts in the southeast China. Its metallization has characteristics of the multiple overprint and multiple sources melange, especially plutonic syn-tectonic intermediate-acidic porphyry.
