2021-8-1 Similarly, the presence of clay minerals promoted the formation of very high-magnesian calcite or protodolomite during the aging of the precipitated materials at a high (8:1) Mg:Ca molar ratio (Liu et al., 2019), even though the nucleation of these phases may be kinetically inhibited in homogeneous solutions (Xu et al., 2013; Zhang et al., 2015).

Read MoreBackground: Bentonite is a natural clay composed mainly of montmorillonite with other associated minerals such as feldspar, calcite and quartz. Owing to its high cation exchange, large surface area and ability to form thixotropic gels with water and to absorb large quantities of gas, it presents a large medicinal application.
Read MoreThere are two main types of chemical weathering. On the one hand, some minerals become altered to other minerals. For example, feldspar is altered — by hydrolysis — to clay minerals. On the other hand, some minerals dissolve completely, and
Read MoreClay minerals are also silicate minerals (see previous pie-chart) that form through the processes involved with weathering of pre-existing silicate minerals in the presence of weak acid and water. As rain forms in the atmosphere, it combines with carbon dioxide to form a weak acid called carbonic acid with the chemical formula, H 2 CO 3 .
