Experimental observations on fungal diagenesis of carbonate substrates

Impact of diagenesis on carbonate mound formation

Impact of diagenesis on carbonate mound formation This thesis is devoted to define the parameters influencing cold-water coral growth and therefore carbonate mound development with a focus on the impact of diagenesis on mound sediments. The first part of this thesis (Chapters 2 to 4) discusses the distribution and growth history of carbonate mounds, the sedimentary processes leading to sediment...

An experimental investigation on drying kinetics of calcium carbonate

Calcium carbonate is a versatile mineral with diverse industrial applications. Drying is a necessary processing step in preparation of calcium carbonate product. Deep knowledge of drying kinetics is required in order to design an appropriate dryer. The main aim of the present study was to investigate the drying kinetics of calcium carbonate, experimentally. Thirteen empirical correlations with ...

Constraints on the formation and diagenesis of phosphorites using carbonate clumped isotopes

The Effects of Sample Treatment and Diagenesis on the Isotopic Integrity of Carbonate in Biogenic Hydroxylapatite

The study of the isotopic composition of structural carbonate in fossil vertebrate hydroxylapatite has been hampered by uncertainty concerning sample treatment and arguments about the susceptibility of this material to diagenetic alteration. Our investigation of sample treatment reveals that some methods commonly used to remove organic matter and secondary minerals induce significant isotopic o...
