归一化总水平导数垂向导数法在宁夏中卫M33异常解释中的应用
|
摘要
以宁夏中卫M33磁异常为研究目标,利用归一化总水平导数垂向导数方法区分岩体与地质体的平面范围,通过极大值的位置判断岩体的边界位置和水平分布。结合磁测井解释成果及相关资料得出,该方法对定性解释岩体分布范围具有较好的应用效果,为以后在此开展相关地质工作提供了依据。
The rock and the geological plane range is distinguished by the normalized total level derivative vertical derivative method and using the location of the maximum value judgment boundary position and horizontal distribution of the rock mass,which is taken the M33 magnetic anomaly of Ningxia Zhongwei as the research target. Combined with magnetic logging interpretation, results and related data prove that the normalized total horizontal derivative of the vertical derivative method has an effective application in qualitative explanation of rock mass distribution, which provide reference for later in the related geological work.
