Abstract Pyrite framboids (spherical masses of nanoscale pyrite) are among the earliest textures pyrite to form in sediments. It has been proposed that their trace-element (TE) contents can be used track TE composition water column which they formed. However, it is not clear how these TEs associated with framboidal grains. For instance, important know whether incorporated uniformly or enriched ...

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...
