Abstract
Many investigators have computed terrain corrections for gravity measurements made in vertical mine shafts (e.g., Rogers, 1952; Domzalski, 1954; Rische, 1957; Vaschilov, 1964) and on structures above ground (e.g., Hammer, 1938; Kumagai et al., 1960; Kuo et al., 1969; Fajklewicz, 1976). The need for a rapid method for calculating terrain corrections for borehole gravity surveys arose with the development of a high-precision borehole gravity meter (Howell et al., 1966; McCulloh et al., 1967). Hearst (1968) was the first to publish a reasonable scheme for rapid computation of terrain corrections to both tower and borehole gravity surveys. Beyer (1971) applied terrain corrections to both tower and borehole gravity measurements using a computational procedure that increased the versatility of Hearst's method. Specific procedures are given by Beyer and Corbato (1972).
