Chemical Potential Gradient between Magma and HostRocks, A Factor for Differentiation

Category Petrology
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 21 May 2008

Abstract:
      Migration of an assembly of ions in from of structural complexes from magma into the host rocks due to chemical potential gradient has not yet considered as a differentiation process in magmatic environment.
   In this article this phenomenon is discussed in term of ionic migration from magma into the host rocks which bring about new metasomatic paragenesis in host rocks and depletion of magma in those migrated ions. The ultimate consequence is a drastic change of path of crystallization of magma in contact zone and creation of special igneous rocks which can not be created by normal known differentiation processes. The chemical potential gradient can easily interpret the existence of these rocks.
