Cleaveland conducted some of the earliest studies of mineralogy in the United States and, in 1816, published Elementary Treatise on Mineralogy and Geology, the first volume on American mineral species and localities ever published, thereby becoming the "Father of American Mineralogy." This comprehensive work, and its revised 1822 edition, with its clear, concise mineral descriptions and useful classification system, was used as the mineralogy textbook in American colleges for many years and set the standard for subsequent works on the subject.
