1. Introduction Mineral replacement reactions occur primarily by dissolution–reprecipitation processes associated with fluid–rock interactions and metasomatism [1]. An important observation is the presence of pores, including micro-pores, in the metasomatic minerals. Experimental studies have confirmed that reactions between minerals and a fluid phase commonly involve pseudomorphic replacement via an interface-coupled dissolution–reprecipitation (ICDR) process (e.g., [2,3], and references therein).
