| บทคัดย่อ/คำอธิบาย | : | We have sampled particles of native aluminium (Alº) in two sediment cores from the Central Indian Basin (CIB). The cores are geographically separated but are located at the base of two seamounts. The native Alº particles occurring as grains and spherules, have an average Al content of ~95% and are associated with volcanogenic-hydrothermal material. Morphologically and compositionally, the specimens are similar to those reported from the East Pacific Rise. After ruling out several processes for the presence of the native Alº, we hypothesize that during progressive melting of magma, a basaltic magma is produced which has high contents of reductants such as methane and hydrogen, and a low oxygen fugacity. During the upward migration of such magma, reduction to metallic aluminium and the formation of native Alº particles takes place. |
