WebIgneous rocks are formed when molten rock cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either the Earth's mantle or crust. Typically, the melting is caused by one or … Web10. apr 2024. · In conclusion, it is likely that the make-up of the mantle conduit exerts a significant effect upon the composition of ascending kimberlite melts at Koidu and Tonguma due to assimilation of highly enriched components from metasomatised mantle rocks by primary carbonate-bearing melts of asthenospheric origin.
