Shatter cones from impact structures worldwide

Fig. 1. Shatter cones in dolostone from the Crooked Creek impact structure (Missouri, USA). Due to rock inhomogeneities, individual, complete cones as shown here are rarely developed.

Fig. 2. Shatter cones from the Rochechouart impact structure (France); subvolcanic dike. Below the coin, see the conic section near the apex of the shatter cone.

Fig. 3. Shatter cone from the Rochechouart impact structure (France); single-cone fragment, gneiss.

Fig. 4. Shatter cone from the Rochechouart impact structure (France); granite.

Fig. 5. Shatter cones from the Rochechouart impact structure (France); granite. Note the small cones riding on each other.

Fig. 6. Shatter cones degenerated into shatter cleavage. Paragneiss, Rochechouart impact structure (France).

Fig. 7. Shatter cone in limestone, Kentland (Indiana, USA) impact structure.

Fig. 8. Shatter cone from the Siljan (Sweden) impact structure; quartzite.

Fig. 9. Shatter coning in granitoid; Suvasvesi South impact structure (Finland).

Fig. 10. Shatter cones in dolomite, Wells Creek (Tennessee, USA) impact structure.

Fig. 11.Shatter coning in granodiorite, Keurusselkä (Finland) impact structure.

Fig. 12. Shatter cone from the Ries impact structure (Germany); granitoid rock from the Bunte breccia ejecta.

Fig. 13. Shatter cone from the Ries impact structure (Germany); hornblende kersantite, inner ring.

Fig. 14. Shatter cones from the Vredefort impact structure (South Africa); arenite.

Fig. 15. Shatter cone from the Vredefort impact structure (South Africa); quartzite.

Fig. 16. Shatter coning in Malmian limestone; Steinheim (Germany) impact structure.

Fig. 16. Single shatter cone in Malmian Limestone; Steinheim Basin (Germany) impact crater.

Fig. 17. Shatter coning in Jurassic limestone from the Steinheim impact structure (Germany). Note the negative cone fracture terminating at the positive cone - or vice versa.

Fig. 18. Shatter cone from the Steinheim impact structure (Germany); Jurassic limestone. Note the fossil as the starting point of the shatter-cone fracture.

Fig. 19. Shatter cone from the Sudbury impact structure (Canada); arenite.

Fig. 20. Shatter cone from the Sudbury impact structure (Canada); quartz arenite.

Fig. 21. Relatively crude shatter coning in arenite from the Sudbury impact structure (Canada).

Fig. 22. Poorly developed shatter cones from the Karrikoselkä (Finland) impact structure; granite.

Fig. 23. Shatter coning in granite from the Saarijärvi (Finland) impact structure.

Fig. 24. Shatter coning in sandstone; Beaverhead (Montana, USA) impact structure.
