Summary

Pelitic units in the eastern Great Smoky Mountains of the North Carolina Blue Ridge contain rutile grains only in kyanite and higher zones. Adjacent non-pelitic rocks do not contain rutile at kyanite grade but commonly contain sphene. Detrital rutile breaks down at metamorphic grades lower than those at which metamorphic rutile forms. Similarly, pelitic rocks in southeastern Connecticut contain rutile grains above, but not below, the sillimanite isograd. Most non-pelitic rocks there contain rutile only in the hypersthene zone. The slight difference in behavior of rutile in the two terranes is attributed primarily to a slight difference in calcium content of the pelites. In both areas, rutile commonly appears first as inclusions in [...]
