Abstract:
The impact cratering as a leading process in the formation of the planetary bodies and surfaces and their geological as well as mineralogical consequences have been summarized in this review article, which is based on PhD. thesis of Arnold Gucsik at Univeristy of Vienna. The purpose of this study is to provide the most important lithological and shock diagnostic features of shock metamorphism accompanied with terrestrial impact structures. The first section of this study gives a brief summary of the formation mechanism and stages of an impact structure as well as a short description of basics of the sock wave physics of an impact event. The next section deals with the types of terrestrial impact structures. The lithological shock-metamorphic indicators and diagnostic shock features in the target rocks are mentioned in the following sections.
