Question

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

Explanation:

To determine the crystal form of Mineral E, we analyze the visual characteristics of the two samples. Equant crystals are characterized by having approximately equal dimensions in all directions, appearing more blocky or rounded - like polyhedrons. The crystals of Mineral E in both samples show a shape where the length, width, and height are relatively similar, with a more compact, block - like or rounded - polyhedral appearance, which is consistent with the equant crystal form. Tabular crystals are flat and plate - like (with one dimension much smaller than the other two), prismatic crystals are elongated (with one dimension much larger), bladed crystals are flat and blade - like, acicular crystals are needle - like (very elongated and thin), and fibrous crystals are in a fibrous or thread - like aggregate. The crystals of Mineral E do not show the characteristics of these other forms.

Answer:

A. Equant
