Abstract

A detailed high resolution ground magnetic survey was conducted over part of the Albion-Scipio Oil Field Trend. The purpose of the survey was to delineate any magnetic anomalies associated with the trend. A field method using two magnetometers was employed. Sixteen simultaneous readings were taken at a mobile and a base station, and the field operator read the total field values using a 'T ', or similar pattern. This method eliminated much of the noise associated with ground surveys. The resulting residual magnetic map indicates that the basement rocks consist of mafic and felsic, dikes and plutons. Several discontinuities are associated with the Albion- Scipio Trend, and anomaly offsets and truncations show an apparent left-lateral fault displacement of 2.5 miles (4.0 km.), thus giving strong and quantitative support to earlier hypothesis of some sort of basement faulting as the controlling factor in the localization of the Albion-Scipio Trend. A change in magnetic trend direction is also associated with the oil trend, and a possible lithologic boundary in the basement has been postulated.
