中文摘要
复活节微板块和胡安·费尔南德斯微板块之间的板块边界似乎在东太平洋隆起有最快的扩张速度。变换断层的缺失表明,在一个可能的阈值扩展率上,经典的扩展中心/变换断层配置是不稳定的。对该地区提出的GLORIA/hydrosweep调查将确定其目前的几何形状和过去4.8万年的构造演化。
英文摘要
The plate boundary between the Easter and Juan Fernandez microplates appears to have the fastest known spreading rate on East Pacific Rise. The lack of transform faults suggests that a possible threshold spreading rate above which the classic spreading center/transform fault configuration is not stable. A proposed GLORIA/hydrosweep survey of this area will determine its present geometry and its tectonic evolution over the past 4.8 m.y.
