Analysis on Ore-Controlling Structures of Jiaojia Gold Deposit in Northwestern Jiaodong Area
Jiaojia is the biggest gold ore field in the northwest region of Jiaodong.Basing on the brief overview of the regional tectonic setting, and combining with the gravity anomaly, gravity extension characteristics and analysis of the ore field structure of Linglong granitic complex; this paper discusses the morphological characteristics of Guojiadian mantle branch structure and its controlling role in the mineralization.In this paper, we think that the multi-stage evolution of the mantle plume connects the deep mineral sources.A series of ductile-brittle shear zone, developing in the peripheral detachment of the Guojiadian mantle branch structure, control the deposits distribution of the Zhaoyuan-Pingdu district.After studying the gold ore-controlling structures, ore distribution, vertical extension and alteration characteristics, we summarize the gold mineralization of Jiaojia, and point out the direction of further exploration in this area.
