【摘要】：为了验证程家村航磁异常圈闭,对该异常圈闭进行了查证工作,针对该区域铁矿体均呈深部隐伏的赋存状态,以"物探先行,钻探验证"的工作方法开展工作,利用地面高精度磁测扫面确定磁异常圈闭平面形态及位置;对高精度磁测剖面数据进行切线法剖面反演,确定强磁性地质体位置和埋深,再结合重磁剖面联合反演方法,推断强磁性地质体的赋存状态,从而给钻探验证提供依据。通过上述工作,取得了良好的找矿效果,表明重磁方法是深部隐伏磁铁矿勘查中的重要工作手段。
[Abstract]:In order to verify the anomalous aeromagnetic traps in Chengjiacun, the abnormal traps are verified. In view of the occurrence of deep ore bodies in the area, the work is carried out with the method of "geophysical exploration first, drilling verification". The plane shape and position of the magnetic anomaly trap are determined by using the surface high-precision magnetic scanning surface, the tangent section inversion of the high-precision magnetic profile data is carried out to determine the location and buried depth of the strong magnetic geological body, and the joint inversion method of gravity and magnetic profile is combined with the method of joint inversion of gravity and magnetic profile. The occurrence of strong magnetic geological bodies is inferred, which provides a basis for drilling verification. The results show that the gravity and magnetic method is an important method in the exploration of deep concealed magnetite.
