Abstract The geochemical behaviors of hydrogen and oxygen isotopes in the hydrothermal system and their inherent relationship with the water / rock exchange are discussed in this paper. In addition to the temperature conditions, the effective W / R ratio is another factor controlling the changes...
Abstract The vegetation has been poisoned by gold in the western Guangdong‐Hainan region. The gold content of the leaves there is as high as 10‐1961 times the abundance, the chlorophyll content is 10%‐30% lower than that of the vegetation in metamorphic terrains and 10%‐20% higher than that in...
Abstract Four detachment systems have been found in the Tarim Basin. They are made up of the Proterozoic, Palaeozoic, Mesozoic‐Eogene and Neogene‐Quaternary, respectively. The shallow‐level detachments are characterized by the occurrence of fold‐thrust belts in the Meso‐Cenozoic. The mid‐level...
Abstract A number of Triassic (245–195 Ma) alkaline or subalkaline igneous complexes were discovered in the Yan‐liao area in the northern part of the North China platform. These complexes are all poor in SiO2; most of them are rich in Fe, Mg, K and P and such incompatible elements as Rb, Ba, U...
Abstract Manganese nodules in areas CP and CC of the central Pacific are rich in REE. Comparatively speaking, the REE contents of nodules in area CP are hihger than those in area CC; and the REE contents of nodules from seamounts are higher than those of nodules from sea‐floor plains and hills....
Abstract The Ordovician Changtu Fauna is recently discovered in the Xia' ertai and Hulan Groups in northern Liaoning‐central Jilin. The fauna, containing 10 genera and 14 species (including 3 new genera, 9 new species and an unidentified species), is closely related in evolution with the Early...
