  • Method and apparatus for the in situ analysis of marine ore concretions
    Patent number: 3942003
    Abstract: For the in situ analysis of marine ore concretions, ore samples are aspirated from the sea floor and introduced in a sample container aboard a carrier body travelling underwater along and in the vicinity of the sea floor. While in the sample container, the ore concretions are exposed to radioactive rays for inducing a secondary radiation emanating from the ore concretions. The secondary radiation is measured for determining the quantity of the individual elements contained in the ore concretions.
