The theory of the Bouguer gravity anomaly; a tutorial

Although the corrections which bring about a Bouguer gravity anomaly are well established, the reasons for doing them are not well understood. One cause of this common misunderstanding is that the subject has been poorly presented in many of the basic texts. This claim was quantified by T.R. LaFehr, a major figure in gravity exploration for 30+ years, in 1991 when he wrote in Geophysics that nine of 15 English-language textbooks contain erroneous statements on this subject.
