Abstract: Based on the theory of dissipative structures and moving character-parameters of elements, this paper examines the characteristics of the geological general field of volcanic belt in the Lancang rift valley, west Yunnan,China. with an open system and lower pressure environment, the volcanic belt is characterized by a large scale continuously graduating dissipative structure and three orders of concentrated minerogenetic material fields,and by the energy fields that influence the time and space structure of material Gelds. The research shows that the third order minerogenetic material fields which surround volcanic eruptive centers and have hydrothermal superposition and reconstruction after the magma stage possess favorable prognosis targets for copper polymetal.
