Economic Mineral Deposits in Impact Structures: A Review ,

In relation to impact, three basic types of ore deposits in impact structure settings have been distinguished: (1) progenetic (ie, pre-impact) deposits that already existed in the target regions prior to an impact event, but may have become accessible as a direct result of the impact; (2) syngenetic (syn-impact) deposits that owe their ....
