“…Rhenium is one of the rarest elements in terrestrial abundance. The standard rocks, G-1 and W-1, contain 0.67 and 0.71 ppb rhenium, respectively (MORRIS and FIFIELD, 1961). NODDACK and NODDACK (1931) determined rhenium contents of various minerals and found that the concentration of rhenium amounted to 20ppm in molybdenites.…”

The rhenium contents of about 200 molybdenites have been determined by the neutron-activation or the catalytic spectrophotometric analyses. The present authors developed these methodes for the determination of the rhenium content of a very wide range, taking only a small amount of each sample.The data obtained show that 1) the rhenium content of molybdenite covers the range from 10-8 to 7 X 10-3 in atomic ratio of Re/Mo, 2) the rhenium contents generally decrease with the following order of occurrence of the molybdenites: volcanic sublimate, porphyry copper deposits, contact-metasomatic deposits, disseminated deposits and quartz veins, 3) as far as plutonic type of molybdenites are concerned, rhenium increases generally with decrease in estimated temperature of molybdenite deposition, 4) the rhenium contents of the molybdenites from Daito area, Shimane Prefecture.as a whole are contrary to the above rule and are higher than those from similar deposits in other areas, 5) low rhenium contents are found in cavity molybdenites, 6) rhenium in an euhedral crystal of molybdenite shows a regular distribution which obeys the Doerner Hoskins' law, indicating that rhenium forms a solid solution with molybdenum.

The occurrence, chemistry, and speciation of rhenium (Re) in environmental components such as soil and water, as well as rhenium separation and analytical characterization techniques in the environment, are summarized. Rhenium has two isotopes: one is stable 185 Re and the other is radioactive 187 Re, which has a very long half‐life of 4.35 × 10 10 years. The decay system, 187 Re– 187 Os has been used for dating rocks and meteorites. Artificially made radioisotopes with short half‐lives, such as 186 Re and 188 Re have been used in radiopharmaceuticals. Because of similarities in chemistry, rhenium has been used as a chemical analog of technetium.
