Determinations on 20-to 80-milligram portions of the rock samples and the -150 mesh fraction of the lunar dust show pronounced Curie points between 680 degrees and 780 degrees C. Remanent intensities of five rock fragments vary from 8.4 x 10(-5) to 0.30 X J0(-5) emu/gram. Upon demagnetization, two of the samples had only viscous magnetization and two other samples had stable magnetizations with remanent coercivities in excess of 50 oersteds. Partial thermal demagnetization suggests that these apparently stable moments may have been acquired in a magnetic field in excess of 1500 gammas. xsxs.
对 20 至 80 毫克的岩石样本和月球尘埃的-150 目部分进行的测定表明，居里点在 680 至 780 摄氏度之间。五个岩石碎片的剩余强度在 8.4 x 10(-5) 到 0.30 X J0(-5) emu/克之间变化。在退磁过程中，两个样本只有粘性磁化，另外两个样本则具有稳定的磁化强度，剩余矫顽力超过 50 奥斯特。部分热退磁表明，这些明显稳定的磁矩可能是在超过 1500 伽马的磁场中获得的。
