Abstract
ABSTRACTThe occurrence of free copper in a new aërolite from Garnett, Kansas, and the aërolite itself are described. To the writer's knowledge, this is but the third time that free copper in a meteorite has been reported. It has been previously detected in specimens of the Richardton, North Dakota (aërolitic), and Xiquipilco, Mexico (sideritic), falls. The largest copper nodule discovered in the Garnett stone has about 25 times as great an exposed surface as had the most sizable fragment reported earlier, measuring 2.0 × 0.6 mm. Since the original writing of the paper, several small grains of free copper have been found in cutting a 9‐lb. individual of the Xiquipilco fall. As free copper is probably present in irons other than those from Xiquipilco, a method of searching for it is outlined. A chemical analysis of the Garnett stone, by F. G. Hawley, is included.
