“…In accordance with the previous pioneering work of Dodd on the Mg/Ca ratios of mussel shells as a temperature proxy 21 , we conducted a couple of measurements on mussel shells with low-resolution mode (30 mm -300 mm). Seawater temperature control on the Mg/Ca ratio has been observed in some previous case studies 22,23 , but was not well reproduced in another case 17 . The discrepancies are partly due to the unknown biochemical and physiological mechanism of Mg incorporation into mussel shells.…”

“…Figure 1b indicates a sulfur concentration map of the specimen measured by an EPMA. There is a signi cant number of condensed bands, possibly due to growth lines with enriched organic matter daily or sub-daily 16,17 . It is, however, di cult to count precisely.…”

“…Then tiny organic matrix located within the mussel shell may be isolated and/or aggregated, forming a layer of enriched organic matter. Macro-molecules such as chitin and proteins in EPF may have an important role to increase Mg/Ca ratio in calcite 17 . This calcite layer should correspond to the stained bands by the Mutivei's solution and sulfur enriched lines observed by an EPMA (Fig.…”

We report here hourly variations of Mg/Ca, Sr/Ca and Ba/Ca ratios in a Mediterranean mussel shell (Mytilus galloprovincialis) collected at the Otsuchi bay, on the Pacific coast of northeastern Japan. This bivalve was living in the intertidal zone, where such organisms are known to form a daily or bidaily growth line comprised of abundant organic matter. Mg/Ca ratios of the inner surface of the outer shell layer, corresponding to the most recent date, show cyclic changes at 25-90 mm intervals, while no valuable variations are observed in Sr/Ca and Ba/Ca ratios. High Mg/Ca ratios were probably established when the bivalve was located at low tide with a reduced supply of Ca from seawater. Immediately following the great tsunami induced by the 2011 Tohoku earthquake, Mg/Ca enrichment occurred, up to 10 times that of normal low tide, while apparent Ba/Ca enrichment was observed for only a few days following the event, implementing a proxy of the past tsunami. Following the tsunami, periodic peaks and troughs in Mg/Ca continued, perhaps due to a biological memory effect as an endogenous clock.

“…The spatial distribution of trace elements in biogenic calcite might be homogeneous or heterogeneous, which relates to the temperature, growth rate, or organic matter content 69 , 107 – 110 . Due to the overgrowth of crystals, the heterogeneous distribution of impurities has been discovered in natural single crystals of low-temperature precipitated calcite 7 , 111 .…”

Divalent heavy metals and uranyl cations incorporated in calcite change its dissolution process

Due to the high capacity of impurities in its structure, calcite is regarded as one of the most attractive minerals to trap heavy metals (HMs) and radionuclides via substitution during coprecipitation/crystal growth. As a high-reactivity mineral, calcite may release HMs via dissolution. However, the influence of the incorporated HMs and radionuclides in calcite on its dissolution is unclear. Herein, we reported the dissolution behavior of the synthesized calcite incorporated with cadmium (Cd), cobalt (Co), nickel (Ni), zinc (Zn), and uranium (U). Our findings indicated that the HMs and U in calcite could significantly change the dissolution process of calcite. The results demonstrated that the incorporated HMs and U had both inhibiting and enhancing effects on the solubility of calcite, depending on the type of metals and their content. Furthermore, secondary minerals such as smithsonite (ZnCO3), Co-poor aragonite, and U-rich calcite precipitated during dissolution. Thus, the incorporation of metals into calcite can control the behavior of HMs/uranium, calcite, and even carbon dioxide.

“…A média do elemento Mg para as amostras analisadas foi de 2840 mg kg -1 , resultado que condiz com os valores informados como referência. (Lazareth et al, 2003), entretanto outros estudo indicam que a incorporação desse elemento depende, de fato, de vários fatores, tais como taxa de crescimento da concha, estrutura cristalina e matéria orgânica (Tanaka et al, 2019). Lazareth et al (2003) (Marali et al, 2017;Geeza et al, 2018).…”
