Towards a Creationist Explanation of Regional Metamorphism

Regional metamorphic rocks are believed to have been subjected to high pressures as well as high temperatures This in addition to the fact that they are always found over areas of hundreds of square kilometres has led geologists to believe that regional metamorphism occurs when the parent rocks are buried to great depths

Metamorphism Wikipedia

Metamorphism is the transformation of existing rock the protolith to rock with a different mineral composition or takes place at temperatures in excess of 150 to 200 °C 300 to 400 °F and often also at elevated pressure or in the presence of chemically active fluids but the rock remains mostly solid during the transformation
