Eighteen minor or trace elelnents were detected and determined by emission spectroscopy. Direct d-c arc excitation of powdered samnples was used with three variations in the procedure. Thirteen lunar samples consisting of four finegrained igneous rocks, one medium-grained igneous rock, seven breccias, and one sample of fines were analyzed. The zinc and nickel concentrations in the breccias were approximately one order of magnitude greater than the concentrations of these elements in igneous rocks.
