Located at the compounding position between SidaoqiaoZhujiding fracture anticline and

SandaoqiaoQingda fracture anticline on the hanging wall of Chengxiang large fault, the Zhujiding

copper deposit is recently discovered in the central segment of Yidun island arc belt. Based on a study

of geochemical characteristics of ore bodies, ores, oreforming age and parent rocks, the authors hold

that the Zhujiding copper deposit is a magmatichydrothermalporphyry type ore deposit formed by

the extensional action of Yidun island arc belt after the collisionorogenic movement in late

Yanshanian period. An oreprospecting model for the Zhujiding copper deposit has been established

on the basis of integrated research.
