Apomagmatic
Definition
Pertaining to mineral deposits or hydrothermal solutions formed at great distances from the parent magmatic hearth or main intrusive body from which they originate; located at the extreme periphery of a zone of plutonic activity. In structural petrology, the term describes mineral precipitation processes occurring at low temperatures where residual fluids are highly diluted by groundwater.
