Santa Fe Shatter Cone
The discovery was made in 2005 by a geologist who noticed shatter cones in the rocks in a decades-old road cut on New Mexico State Highway 475 between Santa Fe and Hyde Memorial State Park

Santa Fe Shatter Cone
Shatter cones are a definitive indicator that the rocks had been exposed to a shock of pressures only possible in a meteor impact - current estimates place the age of the impact between 1.4 and 1.6 billion years old!

Baden-Wurttemberg, Germany
The crater is located at the northeastern end of the Swabian Alb near the much larger Nördlinger Ries crater and was most probably formed simultaneously by the impact of a double asteroid!

Steinheim Shatter Cone
Shatter cones are conical fractures with typical parallel line markings created by shock waves - they are considered to be regular macroscopic shock inventory normally found in rocks of impact structures - our piece is a good example

Suevite Material
In 1960 Eugene Shoemaker and Edward Chao proved that the Ries was caused by meteorite impact - the key evidence was the presence of coesite - shocked quartz - in the local Suevite material indicating high impact shock pressures

Irghizite
Irghizite material is an unusual tektite because they are usually found situated directly in meteorite crater - we have this small glass-like sample from the Zhamanshin crater
