chrysocolla

Intergrowth with other secondary copper minerals such as chrysocolla is also common.

Secondary minerals that can be seen include green malachite and blue-green chrysocolla.

Dioptase and chrysocolla are the only relatively common copper silicate minerals.

I felt a pretty piece of chrysocolla down in the shaft and I wanted to get it for you for your collection.

The primary copper minerals found here were the grayish chalcocite and the bright blue-green chrysocolla.

The dull grey-black color of tenorite contrasts sharply with the often intergrown blue chrysocolla.

This includes chrysocolla.

It occurs in association with hemimorphite, smithsonite, chrysocolla, coronadite and various iron oxides.

A 2006 study has produced evidence the blue mineral chrysocolla may be a microscopic mixture of spertiniite, amorphous silica and water.

It is associated with brochantite, malachite, atacamite, tangeite, chrysocolla, baryte and gypsum.

Tenorite commonly occurs with chrysocolla and the copper carbonates, azurite and malachite.

It occurs in association with cuprite, brochantite, linarite, caledonite, malachite, chrysocolla and its polymorphs.

Other associations are with chalcophyllite, chenevixite, pseudomalachite, bayldonite, tyrolite, azurite and chrysocolla.

It frequently occurs in association with native copper, azurite, chrysocolla, malachite, tenorite and a variety of iron oxide minerals.

Associated minerals include antlerite, molybdenite, powellite, brochantite, chrysocolla, iron oxides and quartz.

The copper deposits consist of malachite and chrysocolla as grain coatings in the Jurassic Navajo Sandstone.

Brochantite is often associated with minerals such as malachite, azurite, and chrysocolla, and may form pseudomorphs with these minerals.

It occurs in association with atacamite, chrysocolla, connellite, cuprite, dioptase, goethite, malachite, plancheite, and tenorite.

Ores most amenable to leaching include the copper carbonates malachite and azurite, the oxide tenorite, and the silicate chrysocolla.

Other associated minerals are apatite, azurite, chalcedony, chrysocolla, cornetite, cuprite, malachite, pyromorphite, tenorite, and iron oxyhydroxides.

Plancheite is a secondary mineral formed in the oxidized zone of copper deposits, associated with other copper minerals chrysocolla, dioptase, malachite, conichalcite and tenorite.

Associated minerals include azurite, malachite, brochantite, chrysocolla, spangolite, connellite, cuprite, cyanotrichite, strashimirite, parnauite, lavendulan, cornubite, langite, clinoclase, pharmacosiderite and mansfieldite.

It occurs in the oxidized zone of ore deposits and is associated with dioptase, wulfenite, hemihedrite, phoenicochroite, duftite, mimetite, shattuckite, chrysocolla, hemimorphite, willemite and fluorite.

Kohl was a dark-colored powder made of crushed antimony, burnt almonds, lead, oxidized copper, ochre, ash, malachite, and chrysocolla (a blue-green copper ore) or any combination thereof.
