Dolomitization in basinal limestones of the Lagonegro Units: from early diagenesis to tectonically-driven fluid flow [PDF]

open access: yes, 2011
The Triassic pelagic carbonates of the Lagonegro Basin Units from the Southern Apennines fold and thrust belt (Italy) are often replaced by dolomites, which in some cases show fabric and petrographic characteristics typical of late burial saddle ...

Effect of Dolomite Addition on The Performance of Palm Oil Mill Fly Ash for Methylene Blue Adsorption

open access: yesIndonesian Journal of Chemical Analysis, 2023
The use of palm oil mill fly ash (FA) as a low-cost adsorbent is one of the solutions for handling FA waste. In this study, the addition of dolomite is expected to improve the adsorbent performance. The aim of this study was to investigate the optimum FA-

Biomineralisation in the Palaeozoic oceans: evidence for simultaneous crystallisation of high and low magnesium calcite by phacopine trilobites [PDF]

open access: yes, 2012
The chemical composition and microstructure of the calcite cuticles of eleven species of phacopine trilobites have been investigated by electron beam imaging, diffraction, and microanalysis, and results reveal that the lenses of their schizochroal eyes ...
