The cycle of formation of clay and clay-based mineral varies dependently of the environment. Weathering of rocks and soil is the primary way that clays and clay minerals form at the Earth's surface today. The weathering process involves physical disaggregation and chemical decomposition that change original minerals to clay …

The future is very bright for the Solid Minerals sector. Though there are key issues affecting the sector globally like skills shortage, finance, global economic downturn, alternative technology, compliance with Regulations and legislations, there are other local issues like, lack of a Mining Cadastre for administration of Mineral titles ...
This article reviews briefly and reconstructs the development of mineralogy as a science starting around 1770 and retells early work on isomorphism and solid-solution behavior …
In the olivine series of minerals, the iron and magnesium ions in the solid solution are about the same size and charge, so either atom can fit into the same location in the growing crystals. Within the cooling magma, the mineral crystals continue to grow until they solidify into igneous rock.
Modern methods of solution mining are typically accompanied by gains and losses of mass via reagent consumption by rock-forming minerals and subsequent clay-mineral …
Coal geology involves research on the components, genesis, nature, distribution, exploration, utilization, and environmental effects of coal, coal seams, coal-bearing strata, coal basins, and coal-associated mineral resources (such as coal bed methane, accompanying elements, and coal-formed oil), based on geological theories …
The complex formula and many substituting ions produce the large number of minerals in the tourmaline group. The International Mineralogical Association has recognized 32 different tourmaline minerals based upon the chemical composition of solid solution series end members. These minerals are listed in the table below.
Chromite is a rare and valuable mineral that contains chromium, a metal used in various industries and products. Learn about its formation, occurrence, uses, and identification at Geology.
With this in mind, the mineralogy of ash and slag from typical coal gasification processes in China are reviewed, including the transformation of minerals typically found in coal, and …
A digital twin is formed using a set of automation tools. The mining and geological information system MINEFRAME integrates and structures the geology and geotechnology data a solid mineral mining in a unified digital space and, thereby, generates a mining plan based on the actual geological information.
A mineral is a naturally occurring, inorganic solid substance that has a specific chemical composition and a crystalline structure. Minerals are the building blocks of rocks, which are made up of one or more minerals. They are typically formed through various geological processes, such as crystallization from a melt (igneous), precipitation from a solution …
New activity–composition ( a – x) relations for minerals commonly occurring in metapelites are presented for use with the internally consistent thermodynamic dataset of Holland & Powell ( 2011, Journal of Metamorphic Geology, 29, 333–383). The a – x relations include a broader consideration of Fe 2 O 3 in minerals, changes to the …
The mining of solid mineral resources is a key driver to economic growth and development. Taraba state is one of the states in Nigeria that is well endowed with different kinds of solid mineral resources that is untouched and yet to be prospected. Some of these mineral resources have been explored and worked on in the past decades.

Ore Geology Reviews aims to familiarize all earth scientists with recent advances in a number of interconnected disciplines related to the study of, and search for, ore deposits. The reviews range from brief to longer contributions, but the journal preferentially publishes manuscripts that fill the niche between the commonly shorter journal ...
Abstract. Mining geology is a specialised area of applied geological sciences that historically evolved as a support for operating mines and for evaluating mining projects. The main objective of mining geology is to provide detailed geological information, and undertake technical and economic studies to evaluate a mining project.
Clay Minerals - Journal of Fine Particle Science publishes research papers about clays, clay minerals and related materials, natural or synthetic. Aspects covered include: Earth Processes (interactions in 'system earth': soil science and geology/mineralogy) including genesis/synthesis, phase transformations, stability, …
Solid solution series. A solid solution series is the compositional range between end-member minerals that share the same basic chemical formula but experience substitution of elements in one or more atomic sites. This substitution occurs when an element in a mineral formula can be replaced by another of similar size and charge to make a new ...
However, the sampling and the mining methods, i.e., the interactions of geologists and mining engineers, have an influence, as shown above with the example of narrow gold-vein mining in Australia. The more complex the grade distribution is, the more critical an effective interaction between geology and mining is.
