| 中文摘要: |
| 随着矿产勘查工作的持续深入，深覆盖区隐伏矿体的定位已成为关键研究课题。山东省近期的勘查实践揭示，该省覆盖区之下的矽卡岩型铁矿床具有巨大找矿前景。本研究以东阿县牛角店覆盖区为对象，系统分析了区域地质特征与重磁异常响应。通过解译重磁数据，构建了研究区的构造格架，并初步厘清了深部岩体的空间展布规律。在此基础上，综合地层形态、岩体分布、构造活动及物探异常等多源信息，与区域矽卡岩型铁矿综合预测模型进行对比分析。研究结果表明，该区具备矽卡岩型铁矿的成矿潜力，并据此圈定了北张、围子董、吕楼及洼里 4个成矿远景区，为后续勘查部署提供了找矿目标与科学依据。 |

| With the continuous advancement of mineral exploration, the targeting of concealed ore bodies indeep-covered areas has become a critical research focus. Recent exploration practices in Shandong Province reveal significant prospecting potential for skarn-type iron deposits beneath its coverage areas. This study systematicallyanalyzes the regional geological characteristics and gravity-magnetic anomaly responses in the Niujiaodian coveredarea of Dong′e County. By interpreting gravity and magnetic data, it establishes the structural framework of thestudy area and clarifies the spatial distribution patterns of deep-seated rock masses. On the basis of the study inte-grates multi-source information, including stratigraphic morphology, rock mass distribution, tectonic activity, andgeophysical anomalies, and compares them with a comprehensive predictive model for regional skarn-type iron de-posits. The results demonstrate that the area possesses favorable potential for skarn-type iron mineralization. Ac-cordingly, 4 prospective metallogenic areas—Beizhang, Weizidong, Lülou, and Wali—are delineated, providing clear targets and a scientific basis for subsequent exploration planning. |
