Question

Complete this identification chart for metamorphic rock using the chart below and find the following mineral present, texture, type of metamorphism, Portolith, and rock name 

Rock sample #32

The image shows a rock sample labeled with the number "32." The rock has a rough, speckled surface with a combination of gray, white, and darker mineral grains. It appears to be resting on a textured black background. There are no graphs or diagrams in the image, only the rock specimen. This type of rock might be an example used in geology studies to understand mineral composition and rock formation processes.
