Abstract

AbstractWe have made an attempt to reconstruct a pre-erosion structure of the Monchegorsk layered intrusion and to assess the parent magma (melt) composition and crystallization conditions. The problem has been solved by simple comparison of the Monchegorsk intrusion structure with a similar analog, that is, the Kivakka layered intrusion, and by modeling using the COMAGMAT software package.
