Geological Setting: The Brevard is located within the Piedmont and represents a tectonic boundary |
|
Geology: Near Rosman the Brevard is located within the Henderson gneiss. The Henderson gneiss is an augen gneiss with the size and number of augens decreasing to the north within the zone proceeding to an ultramylonite. |

|
Further into the zone we reach mylonites with augens still visible. |

|
Another mylonite with the augens getting smaller |
|
Proceeding to an ultramylonite with almost no visible augens remaning |
|

|
The most fine grained ultramylonite we encountered with about one visible augen per square meter. |
