The feldspars are important minerals at Franklin and Sterling Hill, but have not been studied in detail. Of the eight feldspar species known to occur here, only microcline and hyalophane are widespread. The extant work is that of Frondel et al. (1966), which focused on the barium-bearing species, the major silicate hosts for Ba in the Franklin deposit; micas are subordinate hosts. Much more work needs to be done in terms of determining the feldspars’ structural state, trace-element concentrations, petrology, and role in the genesis of the deposits. Feldspars are the most understudied of all significant Franklin minerals. The locally occurring feldspar minerals are listed below.
