Source: What Does the Dewar Magnetic Anomaly Reveal About the Moon’s Ancient Magnetic Field? · locator {} · excerpt hash sha256:266262d41fb60b21fc48f9f106ad2fa728cd159155a0f7020b291b41a8f16fc2

Exact excerpt

Their central estimate places the ancient magnetizing field above approximately 11 microtesla under their adopted assumptions. The paper also presents substantial uncertainty around that estimate, including plausible material properties that could lower it.

Using the average magnetization per unit mass of the strong anomaly, the authors obtain a minimum paleointensity of approximately 11.4 microtesla.

Using basin model ages of approximately 4.31 billion and 4.14 billion years, the paper assigns Dewar a formation age of approximately 4.22 billion years, with an uncertainty of about 80 million years.
