Statistical studies of magnetic anomaly patterns have been made as part of a continuing investigation of anomaly characteristics and their relation to intrabasement tectonic patterns. Surveys exceeding one million square miles in area are included in the study. Anomaly trends are shown to have statistical preference for E‐W, N‐S, NW‐SE, and NE‐SW directions. In individual basement provinces definable by magnetic character, the dominant trend is most often either NS‐SE or NE‐SW. E‐W and N‐S trends are persistent throughout all surveys. Statistical treatment of distances between adjacent parallel anomalies demonstrates that the commonest spacing is approximately 4 miles. Possible relationships to crustal forces and strength are discussed.
