Name:

Lindsleyite is named in honor of Donald Hale Lindsley (22 May 1934 - ), professor in the Department of Earth and Space Sciences, State University of New York at Stony Brook, in recognition of his contributions to mineralogy, to the development of the benchmark, Fe-Ti oxide geothermometer-oxygen geobarometer, and to his high pressure phase equilibria studies in oxide and silicate systems. He was awarded the 1996 Roebling Medal.
