How Does Pressure Change Gneiss

How Does Pressure Change Gneiss. Web regional metamorphism, which is the formation method of gneiss, occurs when the material is deeply buried under the ground, at depths of several miles. Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying composition, while other bands contain granular minerals with an interlocking texture.

What does granite rock turn into after. Web shale at first becomes slate, but given enough time, pressure and heat, it will continue to change into phyllite, schist and then gneiss. Web gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist.
