Tidal deposits from the Pliocene era at Ytri-Tunga, near Húsavík on the Tjörnes peninsula. The deposits are cross bedded and are formed in different directions, one after the other.

A so called dyke on the south coast of the Westfjords. These dykes occur because a crack is filled by molten rock. Typically several dykes occur parallel to each other.

Comments:
By uplifting of the surface this fissure in the rock, which was formed in the 18th century near Laki (road 206) where a large fissure eruption occured. As a result of this eruption, many cubic kilometers of volcanic ash and lava were erupted. Crops were dying en masse, and many people died of starvation.

A cracked lava field near Reykjahlid in northern Iceland. These forms occur because the lava field does not cool evenly after the lava has stopped flowing.

Lava Field with ridges, on the way from Askja to Laugafell via the F910 roed in the north of Iceland. The lava cools the fastest on the surface, leaving a thin crust that ripples due to the the flow of lava underneath.

Comments:
Cross-bedding at Kerlingarfjöll in the middle of Iceland. These structures are probably caused by a sudden flood of water from under the ice sheet in the neighborhood. This so-called Jökullhaup happens when ice has melted under the ice sheet as a result of volcanic activity. When the water makes its way to the outside of the ice sheet, a huge tidal wave will occur. The rock is about 20 meters high.

Fjallsárlón in southern Iceland. Ice sheets like this shaped the landscape is a large area in the northern hemisphere. In the Saalian glaciation the ice came even come The Netherlands and Germany in Europe, and covered a large part of North America.

Comments:
The stratification (limestone from the Jurassic period) in the picture shows a clear cyclicity. This regularly thinning and thickening of the layers may be caused by periodic changes in the position of the Earth's axis, such as, for example, the Milankovich cycles. The harder limestone represent a period of shallower sea level than the softer marly layers that reflect a deeper depositional environment.
