**Rock Classification Table** | **Rock Name** | **Texture** | **Composition** | **Extra** | |---------------|-----------------------------|------------------------------------------------------------|--------------------------------------------------------------------| | Gneiss | Foliated | Thick, dark, and light foliations of minerals | | | Schist | Foliated | Small, thin foliations of minerals | Sometimes, large mineral crystals form in the foliations (like Garnets) | | Phillite | Foliated | Very thin, and wavy foliations of minerals | | | Slate | Foliated | Very thin flat foliations of the same mineral (usually one color) | | | Graphite | Nonfoliated-Unfoliated | Dark gray carbon | Looks metallic | | Marble | Nonfoliated-Unfoliated | Large visible light colored minerals | | | Quartzite | Nonfoliated-Unfoliated | Small grains of sand fused together (usually smaller than grains found in Marble) | | **Explanation**: This table classifies various types of rocks based on their texture, composition, and any additional characteristics. - **Texture**: Describes whether a rock is foliated (layered appearance) or nonfoliated. - **Composition**: Details the mineral content and structure within the rock. - **Extra**: Provides additional features or characteristics that may be observed. For instance, "Schist" is a foliated rock with small, thin layers and may have additional large mineral crystals like garnets.

**Metamorphic Rock Samples** 1. **Sample 1**: This rock appears to have very thin, flat layers. 2. **Sample 2**: Similar to Sample 1, this rock also has very thin, flat layers. 3. **Sample 3**: This sample looks like it is composed of large grains. 4. **Sample 4**: The rock seems to be made up of grains similar in size to sand particles. 5. **Sample 5**: It has thin layers of shiny minerals with large crystals embedded in the layers. 6. **Sample 6**: This rock looks shiny, lacks visible grains, and leaves a grey metallic streak. **Note**: Metamorphic rocks are identified based on their [7] and [8].
