作为对异常特征及其与基底内构造模式的关系的持续调查的一部分,对磁异常模式进行了统计研究。该研究包括面积超过一百万平方英里的调查。异常趋势显示出对 E-W、N-S、NW-SE 和 NE-SW 方向具有统计偏好。在由磁性特征定义的各个基底省中,主导趋势通常是 NS-SE 或 NE-SW。 E-W 和 N-S 趋势在所有调查中都是持续存在的。对相邻平行异常之间距离的统计处理表明,最常见的间距约为 4 英里。讨论了与地壳力和强度的可能关系。
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.
