There is a new awareness recently concerning the connection of our planet to the rest of the cosmos. Throughout geologic time this possibility of an external body impacting the Earth has many times been a reality. These impacts have historically changed the course of life on Earth and the geologic history of the planet. They have also generated and enhanced the conditions for mineral emplacement and concentration which can today be exploited economically. Therefore it is important to understand the appropriate methodology, from the view of potential mineral resources, for addressing these structures of extraterrestrial origin. These methodologies are reported in this article as a contribution to the exploration of unorthodox mineral resources. In fact, there is a double contribution: first, a systematic and systemic methodology to recognize these impacts, second, to propose the necessity for a more "open-minded" approach in nonconventional geologic environment prospecting.
