There are over 100 different borate minerals.

More than one hundred borate minerals contain boron in oxidation state +3.

Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.

Boron most often occurs in nature as borates, such as borate minerals and borosilicates.

The borate minerals are minerals which contain a borate anion group.

Borate minerals include:

Ulexite is one of over a hundred borate minerals; it is a fibrous crystal where individual fibers can guide light like optical fibers.

Some four to six million years old, the Furnace Creek Formation is the primary source of borate minerals gathered from Death Valley's playas.

Many borate minerals, such as borax, colemanite, and ulexite, are salts: soft, readily soluble, and found in evaporite contexts.

In one experiment simulating early Earth conditions, pentoses formed from mixtures of formaldehyde, glyceraldehyde, and borate minerals such as colemanite (CaBO5HO) or kernite (NaBO).

Greisens appear as highly altered rocks, partly coarse, crystalline granite, partly vuggy with miarolitic cavities, disseminated halide minerals such as fluorite, and occasionally metallic oxide and sulfide ore minerals, borate minerals (tourmaline) and accessory phases such as sphene, beryl, topaz, etcetera.
