AbstractRhenium ( Re) is the crucial element in the production of heat resistant superalloys for turbine engines, and it is known as the aviation industry transforming metal. The rhenium deposits predominantly occurred in molybdenites of porphyry copper-molybdenum deposits and sulfides in the reducing sedimentary rocks. At present, nearly half of the rhenium reserves in the world were contained by the porphyry copper-molybdenum deposits in Chile. The total rhenium reserves in Chile estimated by the United States Geological Survey are ca. 1300 tons. The following countries include United States, Russia, Peru and other countries, totaling 300 tons. It is estimated from the available data that the proved rhenium reserves in China are about 250 tons, mainly associated with molybdenites. In geochemical perspective, rhenium is one of the rarest metals on the Earth. As a moderately incompatible chalcophile and siderophile element, rhenium is enriched in magmas. Rhenium is sensitive to sulfur fugacity and oxygen fugacity, which prefer to be enriched in sediments under the reducing conditions, e. g. black shale, during the surface process. Enclosed and semi-enclosed bays are the common places for rhenium concentration. During the Ediacaran and Cambrian periods, the atmospheric oxygen increased greatly, which was the most favorable period for the migration and enrichment of rhenium during the Earth's surface processes. The Ediacaran-Cambrian black shales, formed in offshore environments, are widely distributed in South China. The western Hubei has included several thousand square kilometers of black shale, of which the thicknesses is up to 200 meters and the rhenium concentration reaches 0. 1 x 10(-6 )similar to 0. 6 x 10(-6). The predicted resource of contained rhenium in this area is more than 10, 000 tons, which is potential to be one of the best target for rhenium exploration.
