definition
All the chemical, physical, and biological changes sediment goes through during and after lithification, not including weathering or other surface changes.
Recent studies have focused on wireline interpretation and early diagenesis in hydrocarbon reservoirs from the Middle East, particularly Cretaceous ramp systems.
Dalradian limestones commonly have Sr greater than 1000 ppm, indicating primary aragonite and marine diagenesis.
A series of photographs and detailed explanations are used to highlight the main processes occurring during carbonate diagenesis.
A model of the effects of diagenesis on magnetic mineralogy in deeply buried sequences is proposed.
An important part of the project will be to understand how sediment diagenesis affects the anisotropy of shales.
