Introduction A mineral deposit precipitated from hot, aqueous solution is called hydrothermal solutions. These solutions can originate from various sources, including: Sources of Hydrothermal Fluids The hydrothermal fluids can originate from various geological processes and locations. The Process of Hydrothermal Ore Deposit Formation The formation of a hydrothermal ore deposit is a complex process that … Read more
Metallogeny is the study of the genesis of mineral deposits, with emphasis on their relationship in space and time to regional petrographic and tectonic features of the Earth’s crust. The term has been used for both metallic and nonmetallic mineral deposits.
The term “dispersion” describes how elements disseminated outwards from the place of its origin. A “dispersion halo” is defined as a region surrounding a mineral deposit, characterized by metal concentrations that are lower than the deposit itself but are comparatively higher than the background levels in the surrounding rocks. Dispersion halos can be classified as … Read more
Metallogeny is the study of how mineral deposits form and are distributed across regions and globally, focusing on their relationship to the Earth’s crust’s petrologic and tectonic features over time and space. The evolutionary sequence of changes in the Earth’s crust and mantle over geological time is now widely recognized. These transformations have played a … Read more
Manganese concentrations in the seafloor are particularly well developed in deep, calm waters far from continental margins and active volcanic ridges. Manganese deposits form in ocean basins that receive little sediment that would otherwise bury them. Such areas include abyssal plains and elevated areas of the seabed, such as seamounts and isolated shallow shoals. Potential … Read more
A mineral reserve is a portion of a mineral resource that has been demonstrated to be economically and legally extractable under current socio-economic and operating conditions.
Lithium minerals are naturally occurring compounds that contain economically significant concentrations lithium in various forms, including lithium carbonate, lithium hydroxide, and lithium chloride. The most common lithium minerals include: Lithium Minerals It has been studied those concentrations exceeding 0.5% are feasible to extract lithium. Lithium deposits Lithium deposits are natural concentrations of lithium in rocks, … Read more
The Proterozoic basins around the world shows higher uranium concentration and many deposits are also established in these basins. For example, Proterozoic Athabasca Basin and Thelon Basin; Canada, Paleo- to Mesoproterozoic McArthur Basin; Australia, Paleoproterozoic Roraima Basin; Guyana, Paleo- to Mesoproterozoic Cuddapah Basin and Neoproterozoic Bhima Basin; India etc. The physicochemical conditions are extensively studied … Read more
Gold is a precious metal. Gold was used by almost all the major civilizations in the world. For most culture, both past and present, it has been of a great economic importance. Gold has historically been the only universally accepted medium of exchange. What makes gold so valuable? The most important is its rarity, although … Read more
Ore is aggregate of minerals and that can be can be economically extracted from the rock. Examples : Galena (Lead Ore) Ore Deposit An ore deposit is an accumulation of a particular ore or more than one ore. Most ore deposits are named according to their location (for example, Tummalapalle Uranium Deposit, India), or after a … Read more
