Answer

Explanation:

Step1: Identify crystal size

Fine

Step2: Determine texture

Non - foliated (since no mention of banding or mineral alignment)

Step3: Decide type of metamorphism

Regional (as no information suggesting contact metamorphism)

Step4: Identify rock name using ESRT Page 7 (assuming knowledge of ESRT)

Quartzite (a common grey non - foliated metamorphic rock with fine crystals)

Step5: Identify parent rock

Sandstone (quartzite is typically formed from sandstone)

Answer:

Crystal size: Fine Texture: Nonfoliated Type of Metamorphism: Regional Rock Name: Quartzite Parent rock: Sandstone
