Oct 20, 2011 (A Wilson) - This map area is made up of several units of calcitic and dolomitic marble, with intercalated metasediments (Figure 88). Most of the marble is dolomitic, with only minor amounts of interbedded calcitic marble. The marble is for the most part grey, with varying amounts of pyrite, phlogopite, and calc-silicate material in clots. Metasedimentary units include hornblende amphibolite, hornblende-garnet amphibolite, and quartzite. These units are normally between 50 and 75 m wide, with some of the smaller units pinching out along strike.
Oct 20, 2011 (A Wilson) - Most of the samples from this belt are dolomitic in composition, with low trace and metallic element contents. Silica content is variable throughout the belt, ranging from nearly O to greater than 20 weight percent.
