301矿田位于燕山期某花岗岩体的东部,外接触带为寒武、泥盆纪的变质岩层。两者呈侵入或构造接触。花岗岩具有多期多阶段侵入的特点。矿田内断裂构造发育。北西西、北东东和北北东三组构造控制了矿床的展布。东西向构造带是控矿的基础,新华夏构造是控矿的主导。已控制的80％矿床都集中在构造带的复合部位。矿化类型主要是碎裂岩带类型。矿体
The 301 ore field is located in the eastern part of a granite body in the Yanshanian period. The outer contact zone is a Cambrian and Devonian metamorphic rock formation. Both invaded or constructed contact. Granite with multi-stage multi-stage invasion. Fault structure development in the ore field. The structures of the North West, North Eastern, North and North East three groups control the distribution of the ore deposits. The east-west tectonic belt is the foundation of ore-controlling, and the new Huaxia structure is the dominant ore-controlling. Eighty percent of the controlled deposits are concentrated in the composite belt of the structural belt. The types of mineralization are mainly cataclasitic belt types. Ore body
