東太平洋海隆熱液活動及多金屬硫化物資源潛力研究進(jìn)展
[Abstract]:In this paper, the hydrothermal activity and the investigation of polymetallic sulphide resources in the East Pacific Sea uplift (East Pacific rise,EPR) and its neighbors in China are reviewed. In the last 12 years, the EPR 13 擄N and 1 擄2 擄S polymetallic sulphides, Fe-Si-Mn hydroxyl oxides, hydrothermal columns, metal-bearing sediments and basalt were studied, and the potential of polymetallic sulphide resources near EPR 13 擄N. The mineral composition characteristics of polymetallic sulfides and their relationship with elements and isotopic compositions are revealed, and it is recognized that rapid precipitation of hydrothermal column particles leads to lower REE content and higher Mn content in Fe-Si-Mn hydroxyl oxides near EPR 13 擄N. It is pointed out that there may be a new hydrothermal active region near EPR 13 擄N, and a new method for calculating the abnormal temperature of hydrothermal column is proposed. The chemical alteration of plagioclase microporphyry and Black Tortoise glass edge in basalt near EPR 13 擄N is divided into 5 types and 4 types respectively, and it is preliminarily proved that the basalt near EPR 1 擄2 擄S was formed by mixing magma of E-MORB and N-MORB in different proportions. The enrichment components of basalt in the area may be derived from the hot source magma near the Gal imprison pagos spreading center, and the reserves are estimated according to the morphology of polymetallic sulphide mound accumulations or vent groups. The conservative value (20 million t).) of the reserves of polymetallic sulphide deposits near EPR 13 擄N is given. On this basis, the direction and focus of future investigation and research in the East Pacific seamounts are further clarified.
