在金属矿重力工作中,已广泛应用由布伽异常换算垂直二阶导数(以下简称gzz)的方法。目前常用的计算公式有哈克公式,艾尔金斯公式及罗森巴赫公式,这样换算出的gzz在突出与矿有关的局部异常,研究与成矿有关的局部构造方面,均取得了较好效果。下面推荐一种计算gzz的九点法,其公式为:(为保持正文的连贯性,各公式的推证作为附注,放在文未)。
In the gravity work of metal mines, the method of calculating the vertical second derivative (hereafter referred to as gzz) by the Burgian anomaly has been widely used. At present, the commonly used calculation formulas are the Huck formula, the Alkins formula and the Rosenbach formula, so that the calculated gzz achieves better results in highlighting the local ore-related local anomalies and studying the local structures related to metallogenesis effect. Here is a recommended method of calculating gzz nine points, the formula is: (in order to maintain the consistency of the text, the formula of the proof as a note, on the text).
