1) Shock metamorphic minerals (shocked quartz, coesite, stishovite)
2) Shatter cones
3) Crater or ring structures in the rock strata (also scarps, fractures
and fault structures)
4) Shattered rock breccia (may include "jumbled" and metamorphosed rock)
5) Melt glasses in crater floor area (very uniform composition, volume of
this is related to crater size and impactor energy)
6) Meteorites (Note that meteorites may not be located at the impact site)
7) Tektites (depends on their composition, some tektites may be of
a volcanic origin)
8) Magnetic or gravity anomalies (Chicxulub structure is an example)
