Santa Fe Shatter Cone - New Mexico [8 lbs XL]

Santa Fe Shatter Cone: A Rare Geological Masterpiece

Shatter cones are rare geological features formed by shock waves produced during a meteorite impact. These waves travel through rock at high velocities, creating cone-shaped fractures with radiating striations. Unlike other geological formations, shatter cones can only form under pressures exceeding 2 GPa (gigapascals); conditions unique to hypervelocity impact events.

Material Composition of the Santa Fe Shatter Cone

The Santa Fe Shatter Cone is primarily composed of Precambrian crystalline rocks, including:

• Gneiss: A high-grade metamorphic rock with distinct foliation patterns.
• Schist: Known for its layered appearance and mineral-rich composition.
• Quartz: Often displays planar deformation features (PDFs), a definitive sign of impact shock metamorphism.
• Feldspar:  May exhibit shock-induced twinning and deformation.
• Mica (Biotite or Muscovite): Adds a reflective shimmer.

The distinctive horsetails on the surface are a hallmark of shatter cones, created by the shock waves propagating through the rock. These features are remarkably preserved, thanks to the durability of the host rock.

Technical Details of the Santa Fe Impact Structure

The Santa Fe Impact Structure, where these shatter cones are found, is a scientifically significant geological site:

Location: Santa Fe, New Mexico, USA.

Age: Estimated to be 1.2 billion years old, dating back to the Mesoproterozoic Era.

Size: Approximately 6 kilometers (3.7 miles) in diameter.

Geology: Formed in Precambrian crystalline basement rocks, with evidence of shock metamorphism preserved in the structure.

Shatter Cone Details

Shatter cones from the Santa Fe Impact Structure are some of the most well-preserved examples of shock metamorphism in Precambrian rocks, making them valuable for research and education.
