Enough potash, however, is obtained in the United States for munition purposes from the burning of seaweed on the Pacific Coast, from the brines in a lake in Southern California and from a rock called alunite in Utah. ❋ Gerard, James W (1917)
Pacific Coast, from the brines in a lake in Southern California and from a rock called alunite in Utah. ❋ Unknown (1909)
For each, there are several kinds of geologic concentrations that represent actual or potential resources; consequently, for each we may expect the depletion history to consist of a series of production-history curves, as availability and cost dictate a steplike descent from high-grade hematite to taconite to iron-rich intrusive bodies, and from bauxite to alunite to high-alumina clays. ❋ Earl Cook (2007)
It has been found difficult to explain the presence of the alunite except through the agency of surface oxidizing waters acting on hydrogen sulphide coming from below. ❋ Unknown (1915)
Minor amounts have been extracted in Utah from the mineral alunite (a sulphate of potassium and aluminum), in Wyoming from leucite (a potassium-aluminum silicate), in ❋ Unknown (1915)
In the Goldfield camp (p. 230) the ores are closely associated with alunite in such a manner as to suggest a common origin. ❋ Unknown (1915)
Various potassium silicates -- leucite, feldspar, sericite, and glauconite -- and the potassium sulphate, alunite, have received attention and certain of them have been utilized to a small extent, but none of them are normally able to compete on the market. ❋ Unknown (1915)
Locally other minerals are associated with the ores, as, for instance, in the Goldfield district of Nevada (p. 230), where alunite replaces the igneous rock. ❋ Unknown (1915)
One of the interesting features of this occurrence is the abundance of alunite. ❋ Unknown (1915)
At Goldfield, Nevada, native gold is found in surface igneous flows of a dacite type, which have undergone extensive hydrothermal alterations characterized by the development of alunite (a potassium-aluminum sulphate), quartz, and pyrite. ❋ Unknown (1915)
Of other natural mineral sources, alunite is the most important. ❋ Unknown (1915)
The specimens shown to us sufficiently indicated that it was neither alunite, similar to the rock of Tolfa and Piombino, nor those capillary and silky salts of alkaline sulphate of alumina and magnesia that line the clefts and cavities of rocks, but real masses of native alum, with a conchoidal or imperfectly lamellar fracture. ❋ Unknown (1851)
Gold is associated with extensive zones of vuggy silica, quartz-alunite and quartz-dickite-kaolinite alteration. ❋ Unknown (2010)
The exposed mineralization exhibits characteristics that are typical of productive high-sulphidation epithermal gold deposits, including vuggy silica, multi-stage episodic hydrothermal breccias, colloform and crustiform banded quartz, and deposition of native sulphur, alunite, barite, copper sulphates, sulphides and sulphosalts, limonite and boxworks after sulphides. ❋ Unknown (2010)
Preliminary prospecting at Tinco has identified pervasive quartz-alunite-clay alteration assemblages along with exposures of vuggy silica. ❋ Unknown (2010)
The property covers an 8 km by 2 km zone of intense acid sulphate alteration, including zones of massive to vuggy silica, quartz-alunite and kaolinite that appears to represent the very top levels of a well-preserved high sulphidation epithermal precious metal system. ❋ Unknown (2010)
The Caldera project is located roughly 10 kilometers from the Ixtaca zone and covers an area of intense acid-sulphate alteration including zones of massive to vuggy silica, quartz-alunite and kaolinite over an 8 by 2 kilometre area. ❋ Unknown (2010)
We had your mom over [for the gang] [bang] and we performed an [alunite]. ❋ Kalel (2007)
"[Dogg]! i was alunit on [this one] girl last night."
"wtf is alunit??"
"[All up in it]!" ❋ Blah (2004)
