N and Ne–Ar abundances and isotope ratios are reported for 12 igneous lunar rocks.

Some mare basalts show low 15N/14N ratios, similar to Earth's primordial mantle.

The data suggest that the LMO acquired N from the assimilation of C chondrites.

The anorthositic crust might be N-free but highland breccias trap impact-derived N.
