Abstract:

The long term objective of this project was to understand the processes responsible for the formation and evolution of the oceanic crust. In order to achieve this goal, we initially focused our efforts on understanding the relationship between the physical proper ties of the upper oceanic crust and the physical and chemical processes that control those properties. The aim of this research was to test the hypothesis that the seismic properties of the upper oceanic crust are controlled by the porosity and chemical alteration of the crust.
