What is magma assimilation?

This trade-off ensures that assimilation can proceed without causing the melt to freeze (solidify). Any wall rock fragments that survive more or less intact, without completely melting or dissolving into the magma, are called xenoliths. Surviving wall rock crystals are called xenocrysts. read more

Geology: assimilation the rusult is that you end up with a different sort of rock than you would have, if the magma had not assimilated something into itself, which it could react with and produce something new. read more

Assimilation is that process of magmatic differentiation whereby ascending magmas evolve chemically by recruiting easily melted or dissolved components from the walls of their conduits. Under the agency of heat and magmatic fluids, ascending magmas pick up volatiles, silica, trace elements, and occassionally fragments of wall rock. read more

Igneous rock - Assimilation: Another method of creating different daughter magmas from a parent is by having the latter react with its wall rocks. Consider a magma that is crystallizing pyroxene and labradorite. read more
