Solid solution | chemistry | Britannica
Many solid solutions appear in nature in the form of minerals made under conditions of heat and pressure. One example is the olivine mineral group, particularly the forsterite-fayalite series, whose members vary from forsterite (Mg 2 SiO 4) to fayalite (Fe 2 SiO 4). The two compounds have identical crystal structures and form a substitutional solid solution that can range from 100 percent
Solid Solution in Minerals
The pyroxene minerals are an example of silicate minerals with magnesium and/or iron and/or calcium cations bonded to the Si-O structure. There are two ways to think about the mineral's composition -- you can refer to the cations plus anions as a total of 100%, or you can refer only to the total cations (in this case, Mg+Fe+Ca) as being 100%. For this discussion, let's just think about the

List of Solid Minerals in Nigeria and their Locations
10/02/2018· Now you have seen the list of solid minerals in Nigeria and their states of location. Now I will discuss the major solid minerals starting with coal. Coal was first discovered in 1909 in the South Eastern state of Enugu in Nigeria and it’s exploration began at Ogbete Mine in 1916. This coal of Nigeria happens to be among the best coal in the globe because of it’s low sulphur and ash

Take the alkali feldspar minerals for example, whose end members are albite, NaAlSi 3 O 8 and microcline, KAlSi 3 O 8. At high temperatures Na + and K + readily substitute for each other and so the minerals will form a solid solution, yet at low temperatures albite can only substitute a small amount of K + and the same applies for Na + in the microcline. This leads to exsolution where they

Metamorphic rock Pressure | Britannica
The mineral calcite (CaCO 3), for example, can occur only in rocks that contain sufficient quantities of calcium. The specific pressure-temperature conditions to which the rock is subjected will further influence the minerals that are produced during recrystallization; for example, at high pressures calcite will be replaced by a denser polymorph of CaCO 3 called aragonite. In general

Solid Solid reactions. This process involves minerals reacting with other minerals in the solid state to produce one or more new minerals. Such processes take place during metamorphism and diagenesis due to changing temperature and pressure conditions. No matter what process is involved, a particular mineral cannot form unless the chemical ingredients necessary to make the mineral are

Coloured gemstone mining occurs in a great many countries across the globe, though each specific gemstone might only be found in a handful of mines – or even in just one unique deposit. The nature of the sector is largely shaped by geology and the nature of gemstones themselves, and we trace these roots. Historically dominated by small scale ‘artisanal’ mining, conducted with basic tools

Alum Wikipedia
An alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO 4) 2 ·12H 2 O, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2 ·12H 2 O.Other alums are named after the monovalent ion, such as sodium alum and ammonium alum.

The solid-solid reactions occur when one or more minerals is converted into one or more different minerals. A special case of solid-solid reaction is illustrated by the aluminosilicate polymorphs kyanite, andalusite, and sillimanite.

What is a Mineraloid? Definition, photos and descriptions
Minerals are “crystalline.” In other words, they have an ordered atomic structure. In contrast, mineraloids are “amorphous.” This means that their internal atomic structure is not ordered. Without the ordered atomic structure, mineraloids never produce well-formed crystals. They also do not exhibit the property of cleavage because they lack internal planes of weakness. Obsidian is a

Metamorphic Reactions Tulane University
Because many minerals are solid solutions, it is also possible to have discontinuous reactions that result in a gradual change in composition of the minerals, but not necessarily the formation of new minerals. These reactions are also considered divariant reactions because they occur over a wide range of pressure and temperature conditions. Consider the hypothetical case of rocks that contain minerals
