Abstract

Magnetic measurements have shown that nondiamagnetic minerals in a lunar crystalline rock of type B are (free Fe2+ in paramagnetic pyroxenes) : (antiferromagnetic FeSiO3) : (antiferromagnetic FeTiO3) : (ferromagnetic iron) = 4.3 : 7 : 20 : 0.08 in weight percentage. The abundance of ferromagnetic Fe in the lunar fines is about 7.5 times its abundance in the crystalline rock. The natural remanent magnetization of the crystalline rock of 7.5 x 10-6 emu/ g in intensity may not be attributable to its thermoremanent magnetization.
