Neugrund breccia
Neugrund breccia is a type of rock consisting of gneissic breccia and amphibolite originating from the Neugrund crater.[1] Neugrund breccia is different from Ordovician breccia, which is found in a similar region but was formed millions of years later after a different meteor strike.
Neugrund breccia formed during the
meteor fragments. Glacial action distributed erratics of breccia throughout an area of over 10,000 km2 surrounding the impact site.[2] Boulders of Neugrund breccia can be found in north-western Estonia and are especially concentrated around the island of Osmussaar
.
The largest known Neugrund breccia formation is Skarvan. It is located near the west coast of Osmussaar.
