Separation of Bouguer anomaly map using cellular neural network

Journal of Applied Geophysics, 2001
In this paper, a modern image-processing technique, the Cellular Neural Network (CNN) has been firstly applied to Bouguer anomaly map of synthetic examples and then to data from the Sivas-Divrigi Akdag region. CNN is an analog parallel computing paradigm

Bouguer gravity anomalies in Wales

Geological Journal, 1965
AbstractBouguer 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.

Relative Bouguer anomaly

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

Theory of the Bouguer anomaly

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

2010
Over 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

Density in Bouguer anomalies and its consequences

Journal of Applied Geophysics, 1994
Abstract 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.
