Oxidation of sulfide deposits occur during the geological process called weathering.

For the scientific community, however, it was a chance to study the evolving geological process of a mud volcano.

The exhibition shows various aspects; from the geological process of creation to production, and use of the stone larvikite, the area's main export product.

The coastlines near these areas are typically very irregular, reflecting the same geological process.

Much smaller, and the heat and pressure generated are inadequate for the necessary geological processes.
