Bouguer gravity anomalies in Wales
Geological Journal, 1965AbstractBouguer gravity anomalies in Wales are shown on a quarter‐inch to the mile scale and are described. Regional and residual anomalies are presented on maps, and the origin of the main residual anomalies is discussed.

The Leading Edge, 2004
Corrections to gravity data and the meaning of the term Bouguer anomaly still confuse many of us despite detailed discussions by such gravity practitioners as LaFehr (1991, 1998), Chapin (1996), and Talwani (1998). In his 1991 article, LaFehr pointed out that incomplete treatment of the subject by major exploration geophysics textbooks is a main reason

Geophysics, 1977
Abstract Although the Bouguer anomaly is the form of the gravitational field most commonly utilized for the investigation of geologic problems on land, the true significance of the combined free-air and Bouguer correction is frequently misunderstood by geologists, geophysical students, and many senior geophysicists with ...

On Ambiguities in Definitions and Applications of Bouguer Gravity Anomaly
2010Over decades diverse definitions and use of the Bouguer gravity anomaly found place in geodetic and geophysical applications. We discuss three distinct Bouguer anomalies. Their definitions vary due to the presence or absence of various effects (corrections), such as the geophysical indirect effect and the secondary indirect effects. Here we discuss the

Some 350,000 gravity observations have been compiled, edited and contoured by an automated computer procedure to produce a two colour edition of the Bouguer Anomaly Map of Canada. The intervals between gravity stations varied from a few hundred meters to a few tens of kilometers.

Density in Bouguer anomalies and its consequences
Journal of Applied Geophysics, 1994Abstract Bouguer anomalies are usually calculated considering the zones above sea level as masses with constant density, or varying according to the density of the outcropping rocks. This paper examines the density-induced errors which can result when calculating the Bouguer anomaly in areas of complex geology and morphology.

The theory of the Bouguer gravity anomaly: A tutorial
The Leading Edge, 1996Although 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.

Geology and Bouguer gravity anomalies of the Gulf of Tonkin and vicinity
Energy, 1981Abstract Outcrops of rock types around the Gulf of Tonkin range in age from Cambrian to Recent. The basement complex of the Gulf of Tonkin consists of Carboniferous carbonates and Lower Paleozoic metamorphic rocks. The Gulf of Tonkin and vicinity are comprised of three tectonic units: 1. (1) the Caledonian South China-North Vietnam Foldbelt, 2.
