Research Abstract

This study has been carried out to understand the mechanism of the thermal and chemical evolution of magma chambers. Thus, the following conclusions were reached : 1)Chemical differentiation trend of magmas can be affected by the amounts of bubbles. 2)In basaltic magma chamber, boundary layer fractionation can be important relative to homogeneous fractionation when magmas are hydrous and the magma chambers are located at depth. 3)It took ~3000 yr for basaltic magma to evolve to andesite at Askja volcano, Iceland.
