Summary:
Unit is named the Taliaferro Metamorphic Complex [also appears as Taliaferro Complex]. Consists of thin-bedded white and blue chert, mudstone, graywacke, and basalt. Exhibit evidence of high-grade metamorphism. Unit is exposed as a folded and faulted thrust sheet in an anticlinorium. Thickness is 1000 m. Is in low-angle thrust-fault contact with younger, less-metamorphosed facies of the Franciscan assemblage. Age is Late Jurassic to Late Cretaceous based on radiometric (K-Ar) dating of minerals and whole-rock samples. (B1520)
