Metamorphic Rock Transformation Sequence by sonusk777 is a document available to read on EtoBox.
Barrovian metamorphism transforms shale through a sequence of metamorphic rocks - slate, phyllite, schist, and gneiss - as temperatures and pressures increase deep within the Earth. If temperatures continue rising, the gneiss may partially melt into migmatite and eventually fully melt into magma, forming an igneiss plagiogranite upon solidification. This demonstrates how sedimentary rocks transform through metamorphic stages and can ultimately become igneous, representing one path in the rock cycle that has
