If an intermediate igneous rock undergoes partial melting, a melt will form that is enriched in _________?

the chemical composition of those minerals with the lowest melting temperatures

the chemical composition of those minerals with the highest melting temperatures

iron and magnesium

both B and C

None of the above

Solution

When igneous rock starts melting different minerals magma is formed and different compositions evolve at differerent temperatures. Compositions are formed at lowest melting temperature as well as highest melting temperature in the process of partial melting. Hence the answer is d.
