Magnetic field measurements made from orbit show that there are strong magnetic anomalies on the Moon, but many of these show no clear correlation with known geological processes. Given that the primary magnetic carrier on the Moon is metallic iron, which is considerably denser than the silicate minerals that make up the crust, we might expect that there would be a correlation between the magnetic field and gravity. If the magnetic anomaly were related to iron‐rich impact ejecta, there might also be a correlation between the magnetic field and topography. We use magnetic field, topography, and gravity data to test whether such correlations exist. Our results demonstrate that some magnetic anomalies show statistically significant positive correlations with free‐air gravity and topography, and the magnetic sources within these regions could potentially be iron‐rich impact ejecta. In a few cases, the magnetic anomalies show statistically significant positive correlations with Bouguer gravity, implying that the magnetic anomalies are associated with density anomalies within either the crust or upper mantle. The origin of the vast remainder of lunar magnetic anomalies remains enigmatic.

月球磁场是否与重力或地形相关？

从轨道进行的磁场测量表明，月球上有很强的磁异常，但许多磁异常与已知的地质过程没有明显的相关性。鉴于月球上的主要磁性载体是金属铁，它比构成地壳的硅酸盐矿物密度大得多，因此我们可以预期磁场和重力之间会存在相关性。如果磁异常与富铁撞击弹射有关，则磁场与形貌之间也可能存在相关性。我们使用磁场，地形和重力数据来测试是否存在此类相关性。我们的结果表明，某些磁异常与自由空气重力和地形在统计上呈显着正相关，这些区域内的磁源可能是富含铁的撞击弹射体。在少数情况下，磁异常与布格引力在统计上呈显着正相关，这意味着磁异常与地壳或上地幔内的密度异常有关。其余大部分月磁异常的起源仍然是个谜。
