中文摘要
9415983先令这是对东南太平洋复活节-萨拉-戈麦斯海山和岛链起源的多管齐下的分析调查。目前关于该链起源的模型有四种:简单热点链、泄漏断裂带、描述两个上升对流单体肢体的热线模型、羽脊相互作用模型。主要调查人员在两次前往链条的航行中收集了含有新鲜玻璃的岩石。在这个项目中,他们将获得样品的辐射日期,并确定样品的化学和同位素组成*
英文摘要
9415983 Schilling This is a multiprong analyical investigation of the origin of the Easter-Sala y Gomez seamount and island chain in the southeast Pacific Ocean. At present there are four models for the origin of the chain: simple hotspot chain, leaky fracture zone, hot line delineating the limbs of two ascending convection cells, and plume-ridge interaction. The principal investigators have collected rocks containing fresh glass during two cruises to the chain. In this project they will obtain radiometric dates on the samples and determine the chemical and isotopic composition of the samples ***
