About Loseyite
Formula:
(Mn2+,Zn,Mg)4Zn3(CO3)2(OH)10
Colour:
White to colorless, may be tannish- brown due to staining; colourless in transmitted light. Examination of the type specimen at Harvard University suggests that the color of loseyite can vary when in daylight to "daylight LED" to fluorescent white light.
Lustre:
Vitreous, Sub-Vitreous, Resinous, Silky
Hardness:
3
Specific Gravity:
3.27
Crystal System:
Monoclinic
Name:
Named in 1929 by Lawson H. Bauer and Harry Berman in honor of miner and mineral collector, Samuel R. Losey [December 10, 1830 New jersey, USA - July 26, 1904 USA], of Franklin, New Jersey, USA. Frederack A. Canfield, Jr. briefly mentioned some of his family's 19th century sources for Franklin District minerals: "More Franklin minerals were collected by Samuel Woodruff than by both miners of the Losey family and by the several miners of the Kemble family." Samuel R. Losey's grandfather was Michael Rorick [1749-1832], one of the owners of a forge along the Wallkill River, about 1765, near where the Franklin Furnace was later erected in Hardyston, later called Franklin, New Jersey.
