Question

what is the crystal form of mineral b? mineral b equant tabular prismatic bladed acicular fibrous

Explanation:

To determine the crystal form of Mineral B, we analyze the visual characteristics:

• Equant: Crystals with roughly equal dimensions in all directions (e.g., cubes or octahedrons). Mineral B’s crystals are elongated, so this is incorrect.
• Tabular: Flat, plate - like crystals (e.g., mica). Mineral B’s crystals are not flat - plate - like, so this is incorrect.
• Prismatic: Elongated crystals with a prism - like shape (length greater than width, with flat, parallel faces). Mineral B’s crystals show elongated, prism - like forms, which fits this description.
• Bladed: Flat, blade - like crystals (e.g., some gypsum). Mineral B’s crystals are not flat - blade - like, so this is incorrect.
• Acicular: Very thin, needle - like crystals (e.g., some tourmaline). Mineral B’s crystals are more robustly elongated (not extremely thin/needle - like), so this is incorrect.
• Fibrous: Crystals arranged in long, thin fibers (e.g., asbestos). Mineral B’s crystals are individual elongated prisms, not fibrous, so this is incorrect.

Answer:

Prismatic (the option labeled "Prismatic" among the given choices)
