Name:
Named in 1955 by George Switzer and William Frederick Foshag in honor of Ezequiel Ordoñez [April 10, 1867 San Nicolás Peralta, Lierma, Mexico, Mexico - February 8, 1950 Mexico City, Mexico], professor of mineralogy and geology at the Escuela Nacional Preparatoria, where he also worked on the geologic map of Mexico published in 1889. Ordoñez became an expert in petroleum geology and greatly influenced the development of petroleum extraction. Ordoñez was eventually appointed head of the Instituto de Geología de Mexico.
