Thermodynamics of Minerals and Mineral Reactions
2020-8-18 assemblages in the same or nearby rocks. Minerals that are equilibrated may be analyzed for their solid solutions, and the locus of various univariant equilibria where the Gibbs energy of reaction is zero may be calculated from initial pressure and temperature using only volume and entropy data. If entropy data are lacking for a phase,

Mineral dissolution and precipitation reactions and
2021-1-5 A mineral nucleation phase (day 1 to 6) dominated by cation release due to dissolution and a mineral growth phase (day 8 to 44) dominated by cation uptake due to precipitation were identified. The latter resulted in the formation of considerable mineral mass, which was deposited almost completely on the wafer surface.

Chapter 2 Interactions Between Carbonate Minerals
1990-1-1 This chapter discusses the interactions between carbonate minerals and solutions. In natural systems, carbonates react with a variety of solutions at different pressures and temperatures. The processes involved in these reactions are complex, but depend significantly on the solubility of the carbonate minerals, their surface chemistry, and dissolution and precipitation kinetics.

Mineral Replacement Reactions Reviews in
2009-1-1 Such fluid-solid interactions span a very wide range of possible reactions, and are responsible for most of the mineral assemblages we see in the Earth’s crust. However, before discussing mineral replacement reactions, we will put them into the broader context of fluid-solid interactions by considering some examples of such reequilibration.

Metal cation exchange reactions of ore minerals in
2018-1-3 It is shown that the reaction ability of metal cations of ore minerals in Fe–Mn crusts of the Marcus Wake Rise increases in the following manner: (Co2+ lt; Cu2+ lt; Ni2+) lt; (Mg2+ lt; Mn2+ lt; K+ ≈ Ca2+ ≈ Na+). The composition of the exchange complex of the ore minerals is constant and includes these metal cations. Ca2+ and Na+ are major contributors to the exchange capacity of the ...
