From the original catalog copy: Cordierite is common in the high-grade regional metamorphic rocks of Precambrian age in the central part of the Front Range of Colorado. It occurs in sillimanitic biotite gneisses, commonly associated with garnet and potassic feldspar, and to a lesser extent, in more mafic gneisses in association with gedrite. These occurrences of cordierite resemble those found in many other parts of the world. This study of the Front Range rocks was made to determine the main factors responsible for the assemblages, the degree to which the rocks represent equilibrium assemblages, and the environment in which they formed.
