Rock Identification (ESRT)

I am a rock with a clastic texture and a silt grain size.

I have a foliated texture with a mineral alignment. I am only composed of mica.

I have a clastic texture and the grain size of pebbles, cobbles, and/or boulders embedded in sand, silt and/or clay. My fragments are angular.

I have a nonfoliated texture and can have a grain size of fine to coarse. I am formed from the metamorphism of either limestone or dolostone.

I can come in grain sizes ranging from microscopic to very coarse and am composed of carbon.

I have a nonfoliated texture and can be formed from regional or contact metamorphism. My pebbles may be distorted or stretched.

I can be either crystalline or bioclastic. I am made up of precipitates of biologic origin or cemented shell fragments.

I can be either crystalline or bioclastic. I am made up of precipitates of biologic origin or cemented shell fragments.

I underwent regional metamorphism and have a foliated texture. My grain size ranges from medium to coarse.

I have a nonfoliated texture and a fine grain size. I am made up of various minerals that undergo contact metamorphism.
