8. 海洋山脊形成的新机制（ Ocean ridges: then there were three ） 最近對海床中最遙遠、相對來說也是最難以到達的一些地 方所做的觀測，有可能改變當前關于海床擴展机制的觀點 。在對擴展速度非常慢的西南印度洋和北冰洋山脊體系進 行考察期間，科學家發現了一個以前不知道的海洋山脊類 型。超慢擴展山脊在机械上与兩种已知類型（快速和慢速 ）截然不同，它們是在地幔上涌的有效擴展速度降到大約 每年 12 毫米以下時形成的。這些超慢擴展山脊包括共存的 岩漿增長和非岩漿增長部分，后者是以前人們不知道的一 种增長邊界結构。 （ Articles, p. 405; News and Views ） Chinese version (in Nature)

9. New mechanism for the formation of ocean ridges Recent observations in the most remote and least accessible ocean floor may have significantly changed the current viewpoint on the mechanism of sea-floor spreading. During the investigation in the Southwest Indian Ocean and Arctic Ridges, both of which are known for their very slow spreading, scientists have discovered another type of ocean ridge which is not known in the past. With respect to the mechanism, the formation of ultraslow spreading ridges is completely different from that of the other two known types - fast and slow spreading ridges. The ultraslow spreading ridges were formed when the effective spreading induced by the mantle upwelling was slowed down to 12 mm/yr. These ultraslow spreading ridges comprise the two co-existing components of magmatic and non-magmatic accretion. The latter is an accretionary boundary structure which is unrecognized until the present. Translation (as of Dec. 27, 2004)
