摘要：

We compiled a suite of 490 heat flow measurements from the Pacific Ocean in areas with less than 85 m of sediment. Heat flow patterns at different basement ages vary with topographic relief. Areas with reliefs < 300 meters are conductively blanketed at 40-60 m.y. and may stop convecting at 70-90 m.y. Areas with reliefs > 300 meters are conductively blanketed at 70-90 m.y. and convect out to greater-than-or-equal-to 90-110 m.y.
