Quizplus · Accepted Answer

The presence of finely crystalline calcite and metamorphosed fossils, along with cleavage, indicates that this rock is marble. Greenstone is typically composed of mafic minerals, such as amphiboles and pyroxenes. Quartzite is composed mainly of quartz grains and lacks cleavage. Deformed granite would have a granular texture and visible crystals, and would not have cleavage.
