1. Igneous rocks

2. Include the following: Chemical or Detrital/Fragmental Grain size: clay, silt, sand or pebbles and cobbles One grain size or many? Shape of grains (round or angular) Other properties

3. METAMORPHIC ROCKS Include the following: Foliated or Non-foliated Describe any foliation Minerals present Protolith (you may have to look these up!)

4. Other: Schists are often named for the larger recrystallized minerals in them. Ex. Garnet-Mica schist Sedimentary samples with abundant fossils are often referred to as “fossiliferous”. If rock fragments are present they are “lithographic” Other metamorphic rock types we have in lab: amphibolite (abundant prismatic grains), hornfels, many varieties of schist!
