Theobald Weber is the namesake of Weberite as one of the developers of the Ivigut cryolite deposit in Greenland. Weberite occurs in cryolite deposits. Found in only a few locations worldwide: Greenland, the USA in Colorado and Nevada, Australia, Ukraine, among a couple others. Weberite is somewhat soluble in water.

Named for the first discovered occurrence in the Weddell Sea of Antarctica. This authigenic mineral is a constituent of bottom muds, peat sediments, calcareous lake sediments, and may be formed as part of a reaction of lichen-produced oxalic acid and calcite. Additionally, it can be formed from bat guano and is a known component of human kidney and bladder stones. Weddellite can be found in few, but widespread localities. Weddellite will desiccate to whewellite upon atmospheric exposure.

Named in honor of William Edmond Logan, the first Director of the Canadian Geological Survey as the type locality for this mineral is found at the Francon quarry in Montréal, Québec, Canada. Weloganite can be found only in Canada where it occurs with and in alkali intrusive rocks, and at a locality in South Africa. Weloganite is pyroelectric, meaning it generates a temporary charge when heated, and it also has a blue triboluminescence, or light that is generated when broken due to the breaking of the chemical bonds.

IMA approved (IMA 2012-030). Publlished in Mineral News v. 28 N. 9, Sept. 2012 Igor Pekov, Anthony Nikischer, Martin Jensen, Joseph Leising. Occurs as splendid fiery orange to amber colored doubly terminated, hexagonal crystals to 1mm. Whitecapsite forms in late supergene enriched zones with corroded realgar.
All Whiteite species are named after John S. White Jr., the Associate Curator of Mineralogy in the Department of Mineral Sciences at the Smithsonian Institution in Washington D.C, USA and also founder and former editor of the Mineralogical Record magazine. Whiteite was formerly described as one mineral but has since been split into alternate species depending on the dominant chemical composition of the mineral in question. At only three localities worldwide, Whiteite-(CaFeMg) is found in “complex zoned granite pegmatites” and iron formations.

Named for Robert William Whitmore, a mineral collector and owner of the Palermo No.1 mine in New Hampshire, USA where Whitmoreite finds its type locality. Whitemoreite can be found in several localities in Europe and the Unites States, including the Tip Top, Big Chief, and White Cap mines here in the Black Hills of South Dakota. Occurs as “a secondary mineral in complex zoned granite pegmatites” and can be a product of hydrothermally altered triphylite.
