Summary:Nodular chert (70% quartz, 20% dolomite, 10% calcite) reacted with dolostone to form mantles of calc-silicate minerals. In general, talc, tremolite, diopside, and forsterite occur in sequence as the granite is approached. The two prograde paths equilibrated at X(CO2) > 0.85 after the talc was consumed. [K.A.R.]
