Calcification rate influence on trace element concentrations in aragonitic
bivalve shells: evidences and mechanisms.
Minute co-variations of Sr/Ca ratios and microstructures in the aragonitic
shell of Cerastoderma edule (Bivalvia)--Are geochemical variations at the ultra-scale masking potential environmental signals?
The apical region in this individual was heavily eroded with most of the outer calcitic layer of the shell worn out, and the inner aragonitic
layer visible (Fig.
It is widely believed that the most primitive molluscan shells were entirely aragonitic
(Taylor, 1973; Vendrasco et al., 2011).
rostra of the Turonian belemnitid Goniocamax: arguments from diagenesis.
[2.] Patterson WP, Smith GR, Lohmann KC (1993) Continental paleothermometry and seasonality using the isotopic composition of aragonitic
otoliths of freshwater fishes.
The presence of abundant secondary porosity due to possible subsurface dissolution potential of predominantly aragonitic
and high magnesium calcite skeletal constituents and tectonic deformation (indeed fracture porosity) of Galiat area the Lockhart Limestone can serve as a good reservoir for hydrocarbons.
Generally the original aragonitic
composition of these algae, result in their poor preservation.
structures, such as cuttlefish bone , sea  and land snail shells , sea urchin shells [17, 18, 20], various mussel shells [19, 22-24], pearl powder , corals , and calcite from egg shells , were successfully transformed into various Ca-phosphate bioceramic powders using these novel mechanochemical methods.
Persistent organic components in heated coral aragonitic
skeletons-Implications for palaeoenvironmental reconstructions.
In order to determine the type of mineralogy and diagenetic systems of Tarbur Formation carbonates, major (Mg and Ca) and minor (Fe, Mn, Sr and Na)elements measured in this carbonates, and with against plotted of them, were compared whit other different researchers limits that was presented to determination of Aragonitic
and Calcitic mineralogy.
