Leading study on the partial melting chain reactions between different rock types in the lower crust

The occurrence of various rock types in the deep crust of continental collision zones show definite mutual interactions during partial melting, as revealed by the case study of high-temperature metamorphic rocks occurring near the Syowa Station, Antarctica. The "skarns" developed between pelitic rocks and marble are considered to be the products of the reactions among marble and partial melts of pelitic rocks, which were formed by the infiltration of fluid from the marble. In addition, blocks of Mg-Al-rich granulite containing graphite with spiral growth steps may have experienced partial fusion by the interaction with surrounding marble.
