THE MAGELLAN SEAMOUNTS - EARLY CRETACEOUS RECORD OF THE SOUTH-PACIFIC ISOTOPIC AND THERMAL ANOMALY
- Abstract:
-
We present geophysical, geochemical, and geochronological data from two Early Cretaceous seamounts in the western Pacific Ocean which formed at melt sources in what is now French Polynesia. One seamount has an 40Ar/39Ar mineral age of 119.6 (±0.6, 1 σ) Ma, is flexurally compensated with an elastic plate thickness Te of 10 (±2) km, and is isotopically similar to the island of Mangaia, or toward the HIMU mantle end-member. The second has an age of 100.1 (±0.5, 1 σ) Ma, is compensated with a Te ...
