About HortonoliteHide

Silas R. Horton
from (Fe1.5Mg0.5)2SiO4 to (Mg1.5Fe0.5)2SiO4
Named in 1869 by George Jarvis Brush in honor of Silas Ryneck Horton [June 26, 1820 Goshen/Craigville, New York, USA - July 31, 1881 Goshen/Craigville, New York, USA]. The father of Silas R. Horton was Dr. Willam Horton, also a well-known physician, mineralogist, and geologist who had hortonite named for him. (Note: There are three contemporaneous people named Silas Ryneck Horton in the Goshen region and all born within a few years of each other.)
A variety of Fayalite-Forsterite Series

An intermediate member of the Fayalite-Forsterite Series; also considered as a Mn- and Mg-bearing fayalite.
