- Numerous studies have suggested that carbonation and serpentinization of silicate minerals are controlled by an interface-coupled dissolution-precipitation mechanism (e.g., Putnis, 2002, 2009, 2014; Plümper et al., 2012; Altree-Williams et al., 2015).
- Moreover, this mechanism can lead to the pseudomorphic (isovolumetric) replacement of the parent phase by the product phase, assuming that the dissolution of the parent phase and the precipitation of the product are coupled in both space and time (Brugger et al., 2010; Putnis, 2009; Qian et al., 2010; Altree-Williams et al., 2015).
- However, I'm curious about the question that "could the interface-coupled dissolution-precipitation mechanism necessarily also not lead to pseudomorphic texture generation?".
The interface-coupled dissolution-precipitation mechanism, while often resulting in pseudomorphic replacement of the parent phase by the product phase, does not necessarily always lead to pseudomorphic texture generation.
This is because the generation of pseudomorphic textures depends on several conditions being met, including isovolumetric replacement, conservation of original grain boundaries, and retention of the parent phase's shape and size. These conditions may not always be met in all dissolution-precipitation processes.
Additionally, the generation of pseudomorphic textures can be influenced by a range of factors, such as the rate of reaction, the nature of the parent and product phases, the solution chemistry, and physical conditions like temperature and pressure.
Therefore, while the interface-coupled dissolution-precipitation mechanism often leads to a pseudomorphic replacement, it does not necessarily always lead to the generation of pseudomorphic textures. There can be cases where this mechanism could result in non-pseudomorphic replacement, particularly if conditions are not conducive to maintaining the original form of the parent phase during the replacement process.
