Erythrite, also known as red cobalt, previously cobalt ochre [5]: 172 is a secondary hydrated cobalt arsenate mineral with the formula Co 3 (AsO 4) 2 •8H 2 O. Erythrite and annabergite, chemical formula Ni 3 (AsO 4) 2 •8H 2 O, or nickel arsenate form a complete series with the general formula (Co,Ni) 3 (AsO 4) 2 •8H 2 O. Erythrite crystals

Erythrite, also known as Red Cobalt or Cobalt Bloom, is a secondary hydrated cobalt arsenate mineral that crystallizes in the form of crusts, aggregates and tiny needle-like prismatic crystals. It's a member of the Vivianite family and usually occurs around other Cobalt varieties. It can also be associated with natural Silver.

Erythrite is a delicate transparent or translucent mineral, most commonly formed in magenta, red, or rosy pink colors, and may also be peach or gray. It is often found in combination with other minerals. It is considered a secondary mineral found within Cobalt deposits and used as an indicator mineral.

Erythrite: Mineral information, data and localities. Named in 1832 by François Sulpice Beudant from the Greek έρυθρος, "erythros" for "red". Vivianite Group, Annabergite-Erythrite Series. The cobalt analogue of annabergite and köttigite.

2024年10月13日 · Erythrite, also known as cobalt bloom, is a striking mineral with a vibrant pink to reddish hue. This mineral, part of the Vivianite group, often catches the eye of collectors and geologists alike. But what makes erythrite so special?

Erythrite, which is used as a guide to the presence of cobalt-nickel-silver ores because of its crimson or peach-red colour, occurs as radiating crystals, concretions, or earthy masses in the oxidized zone of cobalt and nickel deposits.

Erythrite is a deeply colored reddish or pink mineral, with its distinctive color caused by its cobalt content. Erythrite is the end member of a series with Annabergite, with Erythrite being the cobalt-dominant member and Annabergite being the nickel-dominant member.

Erythrite, or "Cobalt Bloom" as it is called by miners, is a weathering product of cobalt-containing minerals such as cobaltite. Where weathered cobalt and nickel ores are found, both annabergite, Ni 3 (AsO 4) 2 -8 (H 2 O) and erythrite become important markers.

Erythrite is known for its Crimson, peach, pale pink, pink, purple, and red, which is caused by the presence of cobalt in its chemical structure. It typically occurs as tiny monoclinic crystalline form crystals or crusts on rock surfaces and has a silky to dull luster.

Erythrite, also known as red cobalt, is a secondary hydrated cobalt arsenate mineral with the formula Co₃(AsO₄)₂·8H₂O. It's a member of the vivianite group and forms a complete solid-solution series with annabergite (nickel arsenate).
