Kissenstrukturen
Kissenstrukturen, translated from German as "cushion structures," refers to a type of geological formation characterized by rounded, pillow-like masses of rock. These structures are most commonly observed in volcanic rocks, particularly those formed by the eruption of basaltic lava into water or wet sediment. The rapid cooling of the outer surface of the lava flow by the surrounding water creates a solidified crust, while the molten interior continues to flow, pushing against this crust to form a bulbous, cushion-like shape. As subsequent lava extrudes, it piles up against existing pillows, resulting in an accumulation of these distinctive forms.
The shape and size of Kissenstrukturen can vary depending on factors such as the viscosity of the
