In these cases, halite is said to be behaving like a rheid. Unusual, purple, fibrous vein-filling halite is found in France and a few other localities. Halite crystals termed hopper crystals appear to be "skeletons" of the typical cubes, with the edges present and stairstep depressions on, or rather in, each crystal face. In a rapidly ...
Galena, also called lead glance, is the natural mineral form of lead (II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5] Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

Two commercially important halide minerals are halite and fluorite. The former is a major source of sodium chloride, in parallel with sodium chloride extracted from sea water or brine wells. Fluorite is a major source of hydrogen fluoride, complementing the supply obtained as a byproduct of the production of fertilizer.

Rubus parviflorus, commonly called thimbleberry, [2] (also known as redcaps) is a species of Rubus native to northern temperate regions of North America. The plant has large hairy leaves and no thorns. It bears edible red fruit similar in appearance to a raspberry, but shorter, almost hemispherical.
The upright cylindrical stems are 30 to 50 cm (12 to 20 in) long and 5 to 8 cm (2.0 to 3.1 in) in diameter, with 11 to 24 low, tuberculated ribs. The plant has four to nine central spines that are straight or curly, whitish to brownish, and 1 to 10 cm (0.39 to 3.94 in) long.
