What does «rodocrosita» mean in Spanish?
- Semi-precious stone composed of manganese carbonate, which determines its pink or purple color, which lightens as manganese is replaced by other components in its composition. It occurs in layers or crusts of banded structure, superimposing pink bands of different light to dark shades, of a fibrous texture, and separated from each other by a white to grayish material (a mixture of carbonate of various calciums, magnesium, iron and very low concentration of manganese). They can also occur in the form of stalactites, in which the different layers are observed in a radial and concentric fibrous form. A stalactite can be formed by several growth centers, straight or curved, with a development of up to 30 cm and a diameter of 2 to 8 cm or more.
