ⓘ Burlington mylonite zone

The Burlington mylonite zone is a 1.5 kilometer thick mylonite zone, resulting from the dynamic recrystallization and grain size reduction of rocks, running from Weston, Massachusetts to Lynnfield, Massachusetts and Danvers, Massachusetts. The deformation that formed the zone is believed to be related to the Bloody Bluff Fault. In 1976, R. O. Castle released information indicating that the Paleozoic Early Devonian Peabody Granite intruded the mylonite zone, giving a young age limit for the formation.

Rocks in the zone of the Burlington mylonite, mainly fine-grained, laminated mylonites ranging from gneiss with eye-shaped mineral grains. The area also includes smaller includes quartz schist and chlorite schist and layered air-mylonite the granite.
