A geophysical traverse across the Sierra Madera "Dome" indicates a negative gravity anomaly of 1(1/2) milligals over the zone of brecciation in the center and a residual positive anomaly of (1/2) milligal associated with a positive magnetic anomaly of 25 x 10(-5) oersted to the southeast of the zone of brecciation. Areal surveys are needed before any definite conclusions can be drawn concerning the origin of Sierra Madera. However, gravity and magnetic data can be extremely valuable in establishing criteria for classifying terrestrial and lunar features according to meteoritic and cryptovolcanic origin.
穿越塞拉马德雷“穹顶”的重力测量显示，在破碎带中心区域存在 1(1/2)毫伽的负重力异常，在破碎带东南方向与 25 x 10(-5)奥斯特正磁异常相关的残余正异常。在得出关于塞拉马德雷起源的任何明确结论之前，还需要进行面积测量。然而，重力和磁场数据对于根据陨石和隐火山成因对地球和月球特征进行分类具有极其重要的价值。
