Classification Principles: Metamorphic Facies versus Metamorphic Grade
It was a milestone in the understanding of metamorphic petrology when Eskola (1915) published his concept of metamorphic facies with the intention of replacing the earlier Becke (1913) and Grubenmann (1910) concepts of metamorphic depth zones. Nevertheless this concept of depth zones was elaborated and slightly modified by Grubenmann and Niggli (1924) and remained in use for decades. In the depth zone classification the physical factors of temperature, hydrostatic pressure, and directed pressure (stress) were believed to be strictly correlated in the manner demonstrated in Table 6-1.
