Calcite is a ubiquitous mineral in nature. Heavy alkaline-earth elements with large ionic radii such as Sr2 and Ba2 are highly incompatible to calcite. Our previous study clarified that incompatible Sr2 ions can be structurally incorporated into calcite through crystallization from amorphous calcium carbonate (ACC). In this study we synthesized Sr-doped calcite with Sr/(Sr Ca) up to 30.7
