• The role of Mg in the crystallization of monohydrocalcite (2014, background): “…Mg contents is not unexpected, and confirms both abiotic (Ajikumar et al., 2005; Rodriguez-Blanco et al., 2011, 2009) and biotic (Loste et al., 2003; Raz et al., 2003; Politi et al., 2010) data that demonstrate the importance of Mg in stabilizing amorphous precursors and delaying crystallization.”
• Nanostructure, composition and mechanisms of bivalve shell growth (2008, background): “Furthermore, ACC contains considerable amounts of Mg and it has also been shown that this ion can participate in the stabilization of amorphous phases (ACC or ACP: amorphous calcium phosphate), possibly by inhibiting crystallization in conjunction with ATP before the seeds reach a critical size (Pos”
• Overview of the amorphous precursor phase strategy in biomineralization (2009, background): “One intriguing observation was that in the sea urchin larvae the transient phase is almost anhydrous, as opposed to the stable ACC phases where water constitutes about 15 per cent by weight [ 25 ].”
• An Overview of Biomineralization Processes and the Problem of the Vital Effect (2003, background): “In fact in vitro experiments with proteins extracted from sea urchin larval spicules show that Mg has to be present for these proteins to induce ACC formation, although in lower amounts than is present in seawater (Raz et al. 2003).”
• A route for the direct crystallization of dolomite (2015, background): “This is consistent with studies that showed a direct proportionality between Mg content and crystallization induction time in the calcium carbonate system (e.g., calcite formation; Reddy and Nancollas 1976; Tracy et al. 1998a, 1998b; Loste et al. 2003; Raz et al. 2003).”
