Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Deposit): CONCENTRATION OF U BELIEVED TO BE EPIGENETIC IN ORIGIN AND ASSOCI ATED WITH BENTONITIC CLAYS IN CARBONACEOUS SHALE SEQUENCE CONTAINING F E CARBONATE CONCRETIONS. SECTION CONTAINING MOST U IMMEDIATELY OVERLIE S SANDY SHALE AND CLAY, APPARENTLY THE LATERAL EQUIVALENT OF NEARBY 4- IN. BENTONITIC CLAY. CONCENTRATION COULD BE DUE TO PERCHING OF WATER T ABLE ABOVE IMPERMEABLE CLAY AND TO LOCALIZATION BY FE.
