2021-2-11 Hornblende, calcium-rich amphibole mineral that is monoclinic in crystal structure. Hornblende’s generalized chemical formula is (Ca,Na)2(Mg,Fe,Al)5(Al,Si)8O22 (OH)2. ... In South Africa, it was extensively mined in the beginning of the 20th century, but it became secondary to the mining of amosite and crocidolite.

The hornblende Mineral Group. Hornblende is frequently also used to describe any dark, opaque amphibole mineral without individual analysis. The individual Hornblende minerals appear very similar and can be virtually indistinguishable without complex analysis, and are often just grouped under a Hornblende label without further distinguishing.

Heavy mineral assemblages from the Calentura and Cayo formations are characterized by typical volcanic arc minerals, including diopsidic augite and brown hornblende. Heavy minerals from the Guayaquil Formation consist of green and brown hornblende, diopsidic augite, and a significant proportion of volcanic and authigenic apatite.

Potassium is a light, very soft, silvery-white metal. It is even more violently reactive with water than is sodium. It is so reactive with oxygen, that if exposed to air, it will tarnish to a grayish color in seconds. Potassium occurs with an abundant radioactive isotope, K40. Consequently, potassium metal is almost always faintly radioactive.
