SGER: Development of Hot-Spotting Method

点击翻译按钮获取中文摘要

The authors are developing techniques for use of a geometric relationship between hotspots and the seamounts producted by them that allows the authors to decouple the age-progression from the geometry and accurately determine hotspot locations on the basis of seamount locations alone. They propose to compile a seamount location database and fully develop the technique to address a number of questions. How many hotspots are there? Are hotspots stationary? Which seamounts were created by hotspots? Where are extinct hotspots? What is the temporal and spatial record of intraplate volcanism? Are hotspot fluxes steady? How accurately can absolute plate motions be resolved?
