Question

what is the crystal form of mineral b? (both samples should have the same crystal form)
2 views of
mineral b
equant
tabular
prismatic
bladed
acicular
fibrous

Explanation:

To determine the crystal form of Mineral B, we analyze the visual characteristics of the mineral samples. The images show the mineral with long, thin, thread - like or hair - like structures that are arranged in a way typical of the fibrous crystal form.

• Equant crystals are roughly equal in all dimensions, which does not match the appearance here.
• Tabular crystals are flat and plate - like, not the case for Mineral B.
• Prismatic crystals have a prism - like shape with well - defined faces, but the mineral here is more thread - like.
• Bladed crystals are flat and blade - like, not matching.
• Acicular crystals are needle - like (long and thin but more rigidly needle - shaped), while the mineral here has a more fibrous, thread - like arrangement.

So, the fibrous crystal form is the best match.

Answer:

Fibrous
