Calcite crystal growth orientation: implications for trace metal uptake into coccoliths

Abstract:

Inorganic calcite precipitation experiments were conducted to determine whether inducing specific orientations of calcite crystal growth can cause the enrichment of cations larger than Ca. Malonic acid (CH2(COOH)2), a di-carboxylic acid, was used to poison growth on acute kink sites, promoting growth on obtuse kink sites, causing calcite crystals elongated along their c-axes to form in a mechanism similar to that seen in the growth of E. huxleyi coccoliths. Calcite was precipitated with a ran...
