  • Gravity and Magnetic Investigations into Possible Economic

    The economic ore deposits specifically in the Pea Ridge Mine in Washington County contain known economic minerals and rare earth element deposits. In order to further investigate the Precambrian basement lithologies and the possible locations of additional economic ore deposits, a gravity survey was conducted during the summers of 2013 and 2014Economic 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 (i.e., 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

    May 05, 2015· The age of the complex is unproven, although it has been considered to be Keweenawan (∼1.1 Ga). Because only four boreholes reach the complex, which is covered by 200–700 m of Paleozoic sedimentary rocks, geophysical methods are critical to developing a better understanding of the nature and mineral resource potential of the NEIIC.Malawi Spilpunt,Apr 14, 2007· A large proportion of Malawi is made up of igneous and metamorphic rocks of the Basement Complex of Precambrian, both Archean and Proterozoic, age comprising Archean charnockitic gneiss, granulites, meta-sediments and ultrabasics; Proterozoic sequences are dominated by meta-sediments and older granitoids.
