    Abstract
  • This article relies on the "Global Mineral Resources Information System" and related projects of the China Geological Survey. The spatial and temporal distribution characteristics of the porphyry Cu(Au-Mo) deposit in the Andean orogenic belt of South America is summarized: Influenced by the continuous subduction of the plate, the porphyry Cu(Au-Mo) deposit in the Andean belt is linear and multi-banded. It is characterized by a large number of deposits, concentrated distribution and large scale of deposits in the Central Andes section. At the age of mineralization, there were two periods of the Late Paleozoic Gondwana orogenic cycle and and four periods of the Mesozoic-Cenozoic Andean orogenic revolving cycle. The most important is the late Eocene-Oligocene and Miocene mid-Pliocene. It provides a reference for understanding the ore-forming geological characteristics and metallogenic regularity of porphyry deposits in the Andean belt.
