标题： Depth to magnetic source estimation using TDX contour

摘要： 准确估算磁性源的深度在多种地球物理应用中起着至关重要的作用，包括矿产勘探、资源评估、区域油气勘探和地质测绘。 因此，本文提出了一种快速且简单的方法，用于利用总磁场的TDX导数来估算磁性体的深度。 TDX是磁场的一阶导数，除了边缘检测外，它受噪声影响较小，从而允许更好的深度分辨率。 对噪声的低敏感性使得深度估计更加清晰，并提高了深度确定过程的准确性。 作为相位导数的一种变体，TDX独立于磁化率，可用于识别磁性体的边缘。 除了擅长边缘检测外，它们还可以估算产生异常的磁性源的深度。 在这项研究中，我们探讨了使用TDX导数的等值线来估算深度，假设垂直接触源。 我们通过一个由两个棱柱块模型和一个均匀磁化率为0.001 cgs的简单主教模型验证了该方法的有效性。 结果与已知深度一致，提供了该方法可靠性的证据，尽管假设条件具有限制性，特别是对于主教模型，其中存在大量断层结构。 显示英文摘要

摘要： Accurate depth estimation of magnetic sources plays a crucial role in various geophysical applications, including mineral exploration, resource assessments, regional hydrocarbon exploration, and geological mapping. Thus, this abstract presents a fast and simple method of estimating the depth of a magnetic body using the TDX derivative of the total magnetic field. TDX is a first-order derivative of the magnetic field that, in addition to edge detection, is less affected by noise, allowing for better depth resolution. The reduced sensitivity to noise enables a clearer estimation of depth and enhances the accuracy of the depth determination process. The TDX, as a variant of the phase derivative, is independent of magnetization and can be used to identify the edge of a magnetic body. In addition to excelling at edge detection, they can also estimate the depth of the magnetic source producing the anomalies. In this study, we explore the utilization of contour of the TDX derivative for estimating depth, assuming a vertical contact source. We demonstrate the effectiveness of the method using a two-prism block model and a simple bishop model with a uniform susceptibility of 0.001 cgs. The results agree with the known depth, providing evidence of the reliability of the method despite the restrictive nature of the assumption, especially for the Bishop model, where there are numerous fault structures.
