Abstract

A new method is introduced to determine the top and bottom depth of a vertical line using gravity anomalies. For this, gravity at a distance x from the origin and horizontal derivative at that point are utilized. A numerical value is obtained dividing the gravity at point x by horizontal derivative. Then a new equation is obtained dividing the theoretical gravity equation by the derivative equation. In that equation, assigning various values to the depth and length of vertical line, several new numerical values are obtained. Among these values, a curve is obtained for the one that is closest to the first value from attending the depth and length values. The intersection point of these curves obtained by repeating this procedure several times for different points x yield the real depth and length values of the line. The method is tested on two synthetics and field examples. Successful results are obtained in both applications.
垂直有限线重力异常的一种简单解释方法
介绍了一种利用重力异常确定垂线上下深度的新方法。为此,利用距离原点x处的重力和该点处的水平导数。用x点的重力除以水平导数得到一个数值。然后用理论重力方程除以导数方程得到一个新的方程。在该方程中,对垂直线的深度和长度赋不同的值,得到了几个新的数值。在这些值中,通过参与深度和长度值,得到最接近第一个值的曲线。这些曲线的交点通过对不同的点x重复这一过程多次得到,从而得到线的实际深度和长度值。该方法在两种合成材料和现场实例上进行了验证。在两种应用中均获得了成功的结果。
