/ˈrɑskoʊˌlaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Roscoe , -lite comb. form¹.

Etymology: < the name of Sir Henry Roscoe (1833–1915), English chemist (see quot. 1876) + -lite comb. form¹.

Mineralogy.

A vanadium-containing mineral of the mica group, occurring as minute greenish or brownish scales.Roscoelite is a silicate and hydroxide of potassium, vanadium, and aluminium, K(V,Al,Mg)₂AlSi₃O₁₀(OH)₂. Crystal system: monoclinic.

1876 J. Blake in Amer. Jrnl. Sci. 112 31 The mineral, to which I have given the name of Roscoelite,—in honor of Professor Roscoe, of Manchester, who has done so much for the chemical history of vanadium,—is a well marked species of mica, containing quite a large percentage of vanadium.

1943 R. D. George Minerals & Rocks iii. 92 As an ore of vanadium, roscoelite has been found chiefly in western Colorado.

1974 Encycl. Brit. Micropædia X. 346/3 Vanadium is the 22nd most abundant element in the Earth's crust. Some commercial sources are the minerals carnotite, vanadinite, and roscoelite.

1996 Sc. Jrnl. Geol. 32 127 Roscoelite..occurs in the cores of reduction spots within the Lower Old Red Sandstone that crops out in Gamrie Bay (Moray Firth).
