Named after the Greek words lampro and phyllo, meaning “shining” and “leaf,” respectively, I reference to the mineral’s lustrous, leaf-like sheets that make up its cleavage planes. Lamprophyllite is a rare, but widespread mineral and can be found in localities in Russia, Greenland, Norway, South Africa, the United States, Canada, and Brazil. In the Kola Peninsula rocks in Russia, it occurs in all the surrounding rock types and most of the pegmatites in the massifs.

Named after the type locality at the Susanna mine in the Leadhills in Lanarkshire, Scotland. An uncommon mineral that occurs in oxidized lead sulfide deposits. Localities include, additionally, England, Wales, Germany, Austria, France, Greece, Iran, South Africa, Australia, the USA, and Chile, among some others. Lanarkite fluoresces yellow under X-rays and long-wave ultraviolet light.

Named for its type locality at Langban in Sweden. Langbanite is a rare mineral that can be found only in its type locality and in Japan. It occurs “in crystalline  limestones and manganese-rich skarns in metamorphosed manganese deposits.” Associated minerals include manganoan aegirine, richterite, braunite, mangnetite, hausmannite, rhodonite, and hedyphane.

Named for Victor von Lang, a physicist, crystallographer, and Professor of Physics at the University of Vienna, in Austria. Uncommon, but wide spread, and can be found in England, Ireland, France, Slovakia, Germany, Italy, Namibia, Australia, the United States, Chile, among many others. Langite occurs as a secondary mineral in oxidized copper sulfide deposits, and may be of post-mine in origin.

Named in honor of Dan Lannon who was one of the first to stake claims in the Wilcox district of New Mexico in the United States where Lannonite gets its type, and one of its only two localities. The other locality for Lannonite is at the Anna mine in Germany. Lannonite is a post-mine mineral that is deposited from solutions from a zone of oxidized breccia.

Named for the lanthanum in the composition with the dominance of neodymium over the other rare earth elements. A rare mineral that occurs as a secondary mineral, typically formed by the alteration of weathering of rare earth element-bearing minerals. It can be found in Brazil, Japan, Russia, the United States, Japan, and Norway.
