Magnussonite

Named after Nils Harald Magnusson who was the former Director at the Geological Survey of Sweden and contributed greatly to the knowledge of the Langban mine in Sweden where the mineral finds its type locality. In addition to Sweden, Magnussonite can be found in only one other locality at the Sterling mine in Sterling Hill, New Jersey, USA. At Langban it occurs in a metamorphosed ion-manganese orebody, and in a metamorphosed stratiform zinc orebody at Sterling Hill.

Malachite

Named for the Greek word malachi, meaning “mallow,” after the plant’s leaves in reference to malachite’s green color. Malachite is a common secondary copper mineral with thousands of localities and is found in oxidized copper deposits and in some cases is used locally as a copper ore. Malachite is commonly associated with azurite, as well as with cupite, cerussite, chrysocolla, calcite, and limonite.

Malhmoodite

Commonly, and initially, misspelled Mahlmoodite, this mineral is named for Bertha K. Malhmood who was an Analytical Assistant at the United States Geological Survey. Malhmoodite is a rare mineral that occurs only in two localities: at the Wilson Springs Union Carbide mine in Arkansas, USA and in Kerriack Cove in Cornwall, England. It occurs as Wilson Springs as a secondary mineral in vugs within alkalic igneous rocks and at Kerriack Cove in a mineralized fissure vein.

Manasseite

Named for Ernesto Manasse who was an Italian chemist and mineralogist and Professor of Mineralogy at the University of Florence in Italy for his work on pyroaurite-related minerals. Manasseite is a secondary mineral in ultramafic rocks and can be found in Norway, Russia, the United States, Canada, and Brazil as well as in newer localities in Poland, Sweden, Hungary, and France.
