An AGU Fellow, Yoder served on AGU's Council from 1966 to 1968, and as president of the Volcanology, Petrology and Geochemistry Section from 1961 to 1964.Born on 20 March 1921, Yoder was raised in Cleveland, Ohio, where he graduated from Lakewood High School. He obtained his bachelor's degree at the University of Chicago in 1940 and his Ph.D. in geology at the Massachusetts Institute of Technology in 1948. He received honorary doctorate degrees from the University of Paris VI, France, in 1981 and from the Colorado School of Mines in 1995.

Configurational heat capacity, C p conf , of liquids above their glass transition temperatures have been calculated from high-temperature structural data of liquids. By calibrating configurational heat capacity of individual structural units, the C p conf of the bulk melt was derived from temperature- and composition-dependent behavior of these units. This heat capacity is then used in conjunction with available molar free hindrance energy and frequency factors to compute the viscosity of silicate melts. The viscosities thus obtained concur, within experimental error, with experimentally determined viscosities. Because of the functional relationships between viscosity, diffusivity, and conductivity, the latter parameters can be computed from melt structure data.

Speciation within these glasses was estimated using a physically consistent method for the deconvolution of inhomogeneously
