  Abstract:It’s sure that the main ore-controlling condition of the ore bodies in Ermi copper-gold deposit is   Songdingshan multiple volcanic apparatus by investigation.The multiple volcanic apparatus’center 1ocates in Songdingshan,controlled by the East-West a nd South-North trend cross structure.The center was intruded by early subvolcanic rock(diorite);subordinate volcanoes formed in the diorite contact belt,which were filled with late stage diorite subvolcanic laccoliths and   formed the volcanic apparatus’ circularity struture(inside circularity).The main copper ore bodies concentrate in the granite-porphyries and its neighborhood,the distribution and direction of copper ore bodies are controlled by the contact belt.Combining with the regional metallogenic rule,researches show that there is not only copper but also   gold mineralization prospect in the deposit.According to the geophysics and geochemistry exploration result,two Class I and one ClassⅡprospecting targets are put forward.
