(American Geophysical Union, 2004-06-19)The Louisville seamount trail has been recognized as one of the key examples of hot spot volcanism, comparable to the classic volcanic Hawaiian-Emperor lineaments. The published total fusion ⁴⁰Ar/³⁹Ar data of Watts et al ...

(2007-11-20)The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to tradit ...

(2011-12-30)In this study we present 42 new ⁴⁰Ar/³⁹Ar incremental heating age determinations that contribute to an updated age progression for the Louisville seamount trail. Louisville is the South Pacific counterpart to the Hawai ...

(American Geophysical Union, 2007-06-16)Over the last three decades the first-order correlation in morphology and orientation of seamount trails has been called upon to support the concept of a ‘‘fixed’’ Pacific hot spot frame of reference and to explain the ...

(Elsevier, 2012)We present the geomorphology of the Eastern Samoa Volcanic Province, covering 28,446 km², and depths ranging from ~50-4000 m. A new compilation of available multibeam data reveals 51 previously undocumented seamounts, ...
