Abstract

The natural remanent magnetization (3.7 x 10(4) electromagnetic units per cubic centimeter) and the susceptibility per cubic centimeter (6.3 x 10(-13)) of an 18.5-gram breccia specimen were determined with instrumentation and techniques currently used in paleomagnetism. The relatively low magnetic stability of the rock in the earth's field and in alternating demagnetizing fields precludes considering it as a reliable carrier of paleomagnetism. A magnetic balance study yields an unusually high Curie temperature (750 degrees C) which is possibly diagnostic of metallic Fe containing less than 5 percent nickel. The estimated relative abundance of the iron in the sample is about 0.5 percent.

摘要

用古地磁学中目前使用的仪器和技术，测定了 18.5 克角砾岩标本的天然剩余磁化强度（每立方厘米 3.7×10(4)电磁单位）和每立方厘米磁化率（6.3×10(-13)）。由于该岩石在地球磁场中和交变退磁场中的磁性稳定性相对较低，因此不能将其视为可靠的古地磁载体。磁天平研究得出的居里温度异常高（750°C），可能表明含有镍少于 5%的金属铁。样品中铁的估计相对丰度约为 0.5%。
