Mineral Reactions - Science

Mineral Reactions. As fluids travel through the crust, chemical disequilibrium drives reactions between the fluid and the minerals in the surrounding rocks. At a fundamental level, many of these fluid–rock interactions are solubility-driven mineral replacement reactions. By mimicking natural textures in the lab we can understand some of the ...

Mineral Chemistry - Tulane University

Compositional Variation in Minerals. In our definition of a mineral we said that a mineral has a definite, but not necessarily fixed chemical composition. Here we explore the "not necessarily fixed" portion of the definition. Chemical compositional variation in minerals is referred to solid solution. Although most of us think of solutions as a ...

Metamorphic Reactions - Tulane University

We say that this reaction is a continuous reaction because there is no change in mineral assemblage between T 1 and T 3, but there is a reaction occurring and its effect is to change the compositions of the solid solution minerals. Note the similarity of this idea to the melting behavior of Fe-Mg solid solution minerals, and the similarity to ...

An Acidic Reaction - Minerals Education Coalition

Scientifi c discussion: Upon reaction with 10% hydrochloric acid, carbonate minerals and carbonate-bearing rocks will react to release carbon dioxide gas. The gas appears as bubbles in the solution. This effervescence is often used by geologists to test rocks for the presence of carbonate minerals such as calcite or dolomite.

Feldspar - Wikipedia

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Congruent and incongruent weathering reactions - Britannica

Congruent and incongruent weathering reactions. These acid solutions in the soil environment attack the rock minerals, the bases of the system, producing neutralization products of dissolved constituents and solid particles. Two general types of reactions occur: congruent and incongruent. In the former, a solid dissolves, adding elements to the water according to their proportions in the mineral.

Triangular Plots in Metamorphic Petrology

Many minerals that occur in nature are solid solutions, and thus they can have a variable composition. Solid solution minerals, because of their possible range in chemical composition, do not plot at single point on the composition diagrams, but instead plot along a line or within a field that represents the possible range in chemical compositions.
