    Rampura Agucha is a zinc and lead mine located on a massive sulfide deposit in the Bhilwara district of Rajasthan, India. [1] [2] Rampura Agucha is located 220 km (140 mi) from Jaipur. It is north of Bhilwara, and northwest of Shahpura. Rampura Agucha is 10 km (6.2 mi) southeast of Gulabpura on NH 79. [1] The mine is owned by Hindustan Zinc ...

  3. Pyrite - Wikipedia

    en.wikipedia.org/wiki/Pyrite

    The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .

  4. Sedimentary exhalative deposits - Wikipedia

    en.wikipedia.org/.../Sedimentary_exhalative_deposits

    Sedimentary exhalative deposits ( SEDEX or SedEx deposits) are zinc - lead deposits originally interpreted to have been formed by discharge of metal -bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulfide minerals. [1] [2] [3] SEDEX deposits are hosted largely by ...

  5. Phyllic alteration - Wikipedia

    en.wikipedia.org/wiki/Phyllic_alteration

    Phyllic alteration is a hydrothermal alteration zone in a permeable rock that has been affected by circulation of hydrothermal fluids. It is commonly seen in copper porphyry ore deposits in calc-alkaline rocks. Phyllic alteration is characterised by the assemblage of quartz + sericite + pyrite, and occurs at high temperatures and moderately ...

    Akal Wood Fossil Park is a National Geological Monument of India located in Jaisalmer district, Rajasthan. It is also a Biodiversity Heritage Site.. It is 21 hectares in extent and is located in Akal village, 17–18 km southeast of Jaisalmer city, and 1 km off the NH-68 Jaisalmer-Barmer road, on a stretch of about 10 km 2 of bare hillside.

  7. Mineral redox buffer - Wikipedia

    en.wikipedia.org/wiki/Mineral_redox_buffer

    In geology, a redox buffer is an assemblage of minerals or compounds that constrains oxygen fugacity as a function of temperature. Knowledge of the redox conditions (or equivalently, oxygen fugacities) at which a rock forms and evolves can be important for interpreting the rock history.

  9. Pyrrhotite - Wikipedia

    en.wikipedia.org/wiki/Pyrrhotite

    Pyrrhotite ( pyrrhos in Greek meaning "flame-coloured") is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.125). It is a nonstoichiometric variant of FeS, the mineral known as troilite . Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.
