Description
An account of the resource
A classic example of Barrovian-type metamorphism in Dutchess County, NY associated with the Taconic orogeny. A Barrovian metamorphic sequence displays gradual pressure and temperature increase along the metamorphic gradient, and occurs during regional metamorphism. These zones of pressure and temperature increase are recognizable by the characteristic minerals that accompany them. Dutchess County, NY contains an unusually complete sequence.
This collection contains metamorphic rocks from chlorite grade to sillimanite grade in a tight spatial window which records the regional metamorphic gradient increasing from WNW to ESE. This collection also contains some rocks that mirror the protoliths of the schists and quartzites of the sequence (shales and graywacke).
