Problematyczność identyfikacji impaktu na podstawie geologicznych mikrośladów

Geological record contains macro and micro traces of the impacts. Macro traces are much easier to interpretation and diagnosis. Undisputed micro evidences of the impact are platinum group element anomalies and shock minerals. In the proximal parts of strewnfield may occur spherules, iron spinels, fullerenes or even deformed fossils. Nevertheless, due to problematic in the recognition and determine the origin does not qualify them as clear evidences of the impact.
