WebApr 8, 2024 · The initial step in the crystallization process is Nucleation. The 1st atom in the mass to form a crystal structure becomes a center, and more atoms gather around the nucleus. As this process takes place, more unit cells assemble around the nucleus, and a small seed crystal is formed. WebApr 12, 2024 · With continuous crystallization, the changes in Li isotope compositions of the remaining magmas can be modeled by the Rayleigh fractionation model (Figure 8). The initial composition of parental magma was set as 24 ppm for Li and 0.0‰ for δ 7 Li (Rudnick & Gao, 2003; Teng et al., 2004).
