The Red Lake greenstone belt is Archaean in age (older than 2.5 billion years) and is located in the Superior province of the Canadian Precambrian Shield. It is a fairly typical greenstone belt, being composed of a complex assemblage of lavas, sedime

This paper reviews the literature in data processing and interpretation in gravity and magnetic methods for the period 1964–71. The topics that are covered include gravimetry, reduction of data, automatic contouring, map analysis and filtering, int

A set of gravity observations was taken at 3- to 4-mile intervals along a traverse through the Canadian Cordillera close to the international border. The isostatic reduction and interpretation of these measurements indicate that compensation beneath

In fitting simple models such as prisms or tabular bodies to magnetic anomaly patterns, certain dimensionless groupings of measurements from the anomaly—termed “characteristic estimators”—appear to be more effective than others in achieving s

A method is found for programming the calculation of gravity and magnetic profiles across two-dimensional bodies of arbitrary cross-section for high-speed computers. It is based upon an idea applied recently by Worzel, Landisman and Talwani, of appro

The principle of density profiling as a means of determining Bouguer densities is studied with a view to extending it to include all of the data in a survey. It is regarded as an endeavor to minimize the correlation between local gravity anomalies an

A new method for calculating anomaly patterns and type curves of apparent resistivity and apparent chargeability over three‐dimensional bodies imbedded in a half‐space is practicable. The solution of the boundary‐value problem for a point sourc

A mathematical basis for the application of power spectrum analysis to aeromagnetic map interpretation is developed. An ensemble of blocks of varying depth, width, thickness, and magnetization is considered as a statistical model. With the use of the

Gravity traverses were made along the Rivière aux Pékans and along the Mushalagan River in west-central Québec in 1964 and 1966 in order to make a closer investigation of the large, negative Bouguer anomaly discovered near the Grenville Front in w
