Sign in to saveMineral aus der Gruppe der Carbonate
Malachite is a green mineral made of copper, carbon, and oxygen that typically forms banded patterns and grows in underground spaces where water and hot fluids cause it to crystallize. It has been valued throughout history for its distinctive appearance and has been used as a decorative stone, pigment, and source of copper.

Article · Deutsch
Malachit, auch als Kupferspat sowie Berg- oder Kupfergrün bekannt, ist ein häufig vorkommendes Mineral aus der Mineralklasse der „Carbonate und Nitrate“ mit der chemischen Zusammensetzung Cu2[(OH)2|CO3]. Er ist damit chemisch gesehen ein basisches Kupfercarbonat. Malachit kristallisiert im monoklinen Kristallsystem, entwickelt jedoch nur sehr selten mit bloßem Auge sichtbare Kristalle mit nadeligem bis prismatischem Habitus. Meist findet er sich in Form von massigen oder traubigen, gebänderten Aggregaten in ausschließlich grüner Farbe in allen Variationen von Blass- bis Dunkelgrün.
