通过成矿地质条件分析，吉林省长春市二道区东风硫铁矿矿体呈斜列式分布于石英闪长岩与围岩接触带及围岩外带不同围岩界面上，矿石自然类型：主要为含铜磁黄铁矿，其次为黄铁矿、黄铜矿及磁铁矿；矿石工业类型为：高中温热液型、矽卡岩型。磁铁矿和磁黄铁矿在成矿作用上都与石英闪长岩体有关，矿床的成矿作用表现为多阶段性。
通過成礦地質條件分析，吉林省長春市二道區東風硫鐵礦礦體呈斜列式分佈于石英閃長巖與圍巖接觸帶及圍巖外帶不同圍巖界麵上，礦石自然類型：主要為含銅磁黃鐵礦，其次為黃鐵礦、黃銅礦及磁鐵礦；礦石工業類型為：高中溫熱液型、矽卡巖型。磁鐵礦和磁黃鐵礦在成礦作用上都與石英閃長巖體有關，礦床的成礦作用錶現為多階段性。

Through the analysis of the metallogenic geological conditions, Dongfeng pyrite ore body, located in Erdao District of Changchun City in Jilin Province, is echelon distribution in the contact zone between quartz diorite and surrounding rock with different rock interface, ore natural type: mainly is copper containing pyrrhotite and pyrite, chalcopyrite and magnetite is the second. Ore industry type is: high medium temperature hydrothermal type, skarn type. Magnetite and pyrrhotite are all related to the quartz diorite in the mineralization, and the mineralization of the ore deposit is a multi-stage.
