A bstract In this paper are given details concerning a chondritic meteorite found in 1933 near the La Lande post office in De Baca County, New Mexico. Macroscopic and microscopic mineralogical examinations and chemical analyses are given. The meteorite is composed chiefly of olivine and enstatite (variety, hypersthene), lesser amounts of a dispersed metallic phase, and small percentages of enstatite‐clinoenstatite intergrowths and secondary hematite. On the basis of this investigation, the La Lande meteorite is classified as a hypersthene‐olivine chondrite (Chy). Evidence is presented to indicate that the La Lande aerolite may not be a distinct fall, but may be simply a member of the widely scattered Melrose, Curry County, New Mexico, shower. Three (3) figures and 2 tables are given.
