Intrusion Margins and Associated Fractures:
No definition has been provided for this term.


Fractures caused by igneous activity creates permeability, allowing water to circulate deep beneath the surface thus becoming heated in the process. http://www.indiana.edu/~sierra/papers/2007/burnham.html

Hydrothermal circulation often occurs at the lithologic boundaries of igneous intrusions and along the fractures they induce in the country rock.
