| Abstract: | The Puffin Structure is interpreted from high‐quality 3D seismic data as a small multiringed impact structure formed by collision of a meteorite or small asteroid with unconsolidated, water‐saturated shallow‐marine shelf carbonates during the Middle Miocene (mid to late Serravallian). The impact created a dish‐shaped structure about 2.5 km in diameter with annular rings and no central uplift. |
