For "B" what type of general rock is it? - Sedimentary, igneous, metamorphic?

- Specific rock name? 

### Geological Cross Section Analysis: West to East This educational diagram provides a cross-sectional view of geological formations, emphasizing various stratigraphic and structural features. Here's an explanation of the elements presented in the diagram: **Labels and Features:** 1. **Units (A-J):** - The diagram has several geological units labeled from A to J, depicting different rock layers or formations. - These units are drawn with solid lines, showing their extent and contact with one another. 2. **Distances:** - The horizontal distance is depicted on the diagram, running from west to east, with a scale of 200 meters. - The vertical scale has a reference point of 800 meters, indicating significant depth and elevation differences among the geological units. 3. **Types of Boundaries:** - **Contact Metamorphism:** Represented by dotted lines, these are zones where rock has been altered by heat due to the intrusion of molten rock. - **Unconformity:** Shown by wavy lines, indicating a surface where rock layers are missing due to erosion or non-deposition, signifying a gap in the geological record. - **Marker Bed in Unit I:** Dash-dot lines mark a specific bed within Unit I, used for correlation or as a reference point. 4. **Structural Features:** - **Fault Line (H):** A solid, black line marked with an arrow, indicating a fault, a break in the Earth's crust where rocks have slipped past each other. - **Folds (L, K):** Symbols pointing to regions where rock layers have been deformed due to compressional forces, resulting in bends or folds. 5. **Directional Indicators:** - **E - E':** The cross-section line is marked by 'E' and 'E'', showing the lateral extent of this geological portrait from west (E) to east (E'). **Explanation of Specific Features:** - **Contact Metamorphism:** - Typically occurs near igneous intrusions, where the intense heat alters the surrounding rock. This process is detailed in the diagram near the marked dotted lines within several units. - **Unconformity:** - Unconformities are crucial in understanding the geological timeline. The presence of wavy lines between several units (like between units E and J, and units D, C, B, etc.) signifies periods where deposition stopped, and erosion removed
