Gravity data are often used for delineation of the lateral and vertical extension of mineralized bodies buried at different depths. Various parameters associated with the buried bodies are the primary concern for mineral exploration purposes. Hence, a reliable and efficacious interpretation method is developed for the delineation of gravity anomaly data over the 2D vertical and horizontal sheet with finite length and width associated with mineralized bodies. The parameters viz. amplitude coefficient (k), location (x₀), depth to the top of the body (h), length of the sheet (L), and shape factor (q) for 2D vertical sheet-type structure and depth (h) and width (w) of the sheet for 2D horizontal sheet were resolved. Restricting x₀ and q has given very reliable results for the 2D vertical sheet, and the w for 2D horizontal sheet shows the problem of equivalence. However, in all cases, the delineated parameters are within the expected uncertainty. The present interpretation method was applied to synthetic and noisy data and three field examples from the USA, Canada, and Sweden for mineral exploration purposes. It has also been seen that the present study is more reliable in delineating the actual structure associated with mineralized bodies for the 2D vertical and horizontal sheet-type structure. The delineated parameters are in outstanding agreement with the earlier works, borehole information and also updated the actual subsurface structure.

长度和宽度有限的二维垂直和水平薄板上重力异常的解释

重力数据通常用于描绘埋在不同深度的矿化体的横向和纵向延伸。与矿藏相关的各种参数是矿产勘探目的的主要考虑因素。因此，开发了一种可靠而有效的解释方法，用于在二维垂直和水平方向上描述重力异常数据，该二维垂直和水平方向上具有与矿体相关的有限的长度和宽度。参数即。二维垂直薄片类型结构的振幅系数（k），位置（x ₀），到人体顶部的深度（h），薄片的长度（L）和形状因子（q）和深度（h）和宽度（解决了二维水平图纸的w）问题。限制x ₀和q对于二维垂直图纸给出了非常可靠的结果，而w2D水平图纸显示了等价问题。但是，在所有情况下，描绘的参数都在预期的不确定性范围内。本解释方法适用于合成和嘈杂的数据以及来自美国，加拿大和瑞典的三个现场实例，用于矿物勘探。还已经看到，对于二维垂直和水平片状结构，本研究在描述与矿化体相关的实际结构方面更为可靠。所描绘的参数与早期的工作，井眼信息以及更新的实际地下结构都非常一致。
