Shatter Cone

Reference work entry
DOI: https://doi.org/10.1007/978-1-4614-3134-3_434

Definition

“Shatter cones are distinctive multiple sets of striated conical fractures that develop at relatively low shock pressures in the rocks of terrestrial impact structures” (Dietz 1959, citation from French and Koeberl 2010).

Synonyms

Pressure cone (obsolete)

Description

Distinctive conical fractures exhibiting radiating and hierarchic multiscale V-shaped striations (“horsetail structures”) (Dietz 1959) that form naturally in impact structures (Fig. 1). They are considered the main macroscopic diagnostic observations for convincing identification of an impact structure (French and Koeberl 2010).
