The gravity anomaly of two‐dimensional sources with continuous density distribution and bounded by continuous surfaces

摘要: The gravity anomaly of a complicated two‐dimensional (2-D) source having arbitrary surfaces and density varying in either horizontal or vertical direction is calculated using combination closed form solutions numerical integration. can be defined by continuous piecewise functions the integration interval. For example, anomalies for intrusions folded sedimentary units, an polynomial distribution direction, represented dimension. When modeling dipping layered beds are dimension which case function depth polynome coordinate. accuracy method user. gives simple general equations to calculate c...
