通过对司家营铁矿大贾庄矿段地质特征的研究,初步确定了主要的矿石类型为磁铁石英岩,矿石结构较复杂,多呈细纹状和条纹状,矿石性质相对简单。太古界滦县群司家营组的黑云变粒岩为重要的找矿标志,矿区构造以褶皱和断裂为主,控制着矿体的产出形态。矿区磁异常和重力异常与铁矿的规模大小密切相关,因此磁异常与重力异常均高区应为本区找矿勘探的重点区域。
Through the study on the geological characteristics of the Dagazhuang ore section in the Shijiaying Iron Mine, the main type of ore is initially identified as magnetite quartzite. The ore structure is complex, mostly finely striped and striated, and the ore properties are relatively simple. The Archean Silurian granulite in the Luanxian Group in the Archean is an important mineral prospecting indicator. The structure of the mining area is dominated by folds and faults, which control the ore body’s output pattern. The magnetic anomalies and gravity anomalies in the mining area are closely related to the size of the iron ore. Therefore, the areas with high magnetic anomalies and gravitational anomalies should be the key areas for prospecting and prospecting in this area.
