Dear colleagues,
I think this problem not so great as it seems. In my view, the term "contact metamorphism" can
be used in all cases when relations between plutons and products of their activity are clear.
Necessary only to show the concrete geological situation and concrete P-T conditions, using,
for example, mineralogical thermobarometry. And after that the task will be solved if it is deep
seated contact metamorphism or not.
By the way I believe that transformations at contact processes can be recognized mostly in low-
grade host rocks because of temperature conditions of high-grade and contact metamorphism
are close. But it depends from concrete geological situation.
Cheers,
Vyacheslav.
