TL;DR: Results verify theoretical predictions and evidence that the isotopic disequilibrium commonly observed in speleothems and scleractinian coral skeletons is inherited from the dissolved inorganic carbon pool of their parent solutions.

TL;DR: Casella et al. as discussed by the authors used four screening methods: cathodoluminescence (CL), cryogenic and conventional field emission-scanning electron microscopy (FE-SEM), and electron backscatter diffraction (EBSD) to assess diagenetic alteration and overprint on measurements of optical overprint signals, changes in calcite crystal orientation patterns, and crystal co-orientation statistics.

TL;DR: It is found that ion transport from OME cells to developing fibres occurs at regions of closest contact between cells and fibres, however only at sites where the extracellular membrane at the proximal fibre surface is not developed yet.

TL;DR: In this paper, the authors demonstrate that brachiopods form their calcite shells under strong biological control, which enables them to survive and grow under low pH conditions and even in seawater strongly undersaturated with respect to calcite (pH = 7.35, Ωcal = 0.6).

TL;DR: In this article, the authors analyzed the oxygen isotopic composition of modern brachiopod shells with high-resolution (20-50μm) resolution, focusing on differences between the primary, secondary and tertiary layers.
