1.477 µm alunite absorption is readily identifiable in all mixture spectra, suggesting that this is a good alu-nite indicator. Al-OH absorptions at 2.166 and 2.208 µm are pre-sent in both alunite and kaolinite, so the primary differ-ence observed in the mixtures appears as a change in presentation. The 2.166 µm absorption is much broader

This weighting by wavelength is the primary determinant of the sensor's capability to resolve details in the spectral signal. To see why this is so, we will take the reflectance data for the mineral alunite ( Chapter 1 ) in the vicinity of the OH absorption doublet between 1350 and 1550nm wavelength, and simulate its measurement by a ...

Apr 11, 2017· Argillic and Advanced Argillic alteration are shallow types of alteration encountrered in a variety of different types of hydrothermal systems. Argillic alteration forms at lower temperatures and primarily consists of kaolinite + montmorillonite clay minerals. Advanced Argillic alteration forms at higher temperatures and lower pH conditions (e ...

Primary alunite formed during the hydrothermal phase, which at some locations involved gold metallization, whereas secondary alunite formed during super~ gene alteration. Stable sulfur isotopes are an aid in distinguishing primary and secondary alunite because the sulfur of primary alunite is notably enriched in S a4.

Primary sulfate minerals may occur in veins, these minerals include; Hauynite, noselite, barite, anhydrite, gypsum (primary and secondary mineral), celestite, alunite (primary and secondary mineral), creedite, and thaumasite. Primary minerals can be used to analyze …

If alunite is indeed primary, its presence provides important constraints on the chemistry of the ore fluid. Thus, determination of the genesis of alunite is critical to the understanding of the geologic history of these ore deposits. At the Post deposit in Nevada K/Ar ages of alunite are much younger than the age of …

Mar 03, 2015· Alunite mineral was recently identified at the upper Eocene clay deposits associated with laminated primary gypsum and iron oxide in Central Tunisia, particularly at El Gnater site. The alunite characterization has been performed by several analytical techniques [atomic absorption spectroscopy (AAS), X- ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetric analysis …

the mineral to retain primary Ar-gas compositions in its matrix or to retain primary fluid compositions in its fluid inclusions. In this study, the noble gas and active gas contents of fluid extracted from inclusions and mineral matrix of alunite from the 1.87 Ga Tapajo´s gold district were analyzed. The active gases referred to are N. 2,CH. 4 ...

Three gas retention sites are recognized in alunite: (1) primary fluid inclusions, (2) crystal structure OH sites, and (3) crystal structure sulfate sites. Alunite undergoes OH loss at <500°C, and K-SO 4 structural decomposition occurs at >600°C. Fluid inclusions generally are ≤1 μm in diameter and have variable but high vapor/liquid ratios.

What is the primary cause? Iron sulfide mineral oxidation catalyzed by bacteria. Iron sulfide minerals responsible: acid volatile sulfide > marcasite > pyrrhotite > pyrite. Other sulfide minerals: copper, nickel, mercury, etc. sulfides do not oxidize readily in air and water to produce acid.

Primary Commodities Copper is the primary commodity of economic interest in most porphyry copper deposits, although some deposits with low to very low copper grades are mined principally for their gold (for example, Çopler, Turkey) and(or) molybdenum (for example, Sierrita, Arizona; Continental [Butte], Montana) resources.
