Our transcription: The effect of cooling rate, water content, and magma compositions on the resulting textures of intrusive igneous rocks can be investigated in a more complete and quantitative way using laboratory experiments.
But a lab alone cannot recreate the geologic processes that cause a magma to form.
These processes operate deep within the Earth's interior, and they're usually tied to tectonic processes and the movement of plates.
