Abstract

The Tuscarora Quartzite is the most important source of silica refractory raw material in Pennsylvania. Quantitative estimations of quartz %, silica cement %, Fe 2 O 3 and mean length of quartz grains, when applied in the form of a discriminant function, are found to differentiate between the refractory and nonrefractory occurrences.
