[HTML][HTML] Overlap** hotspot tracks and melts from diffuse plume materials in the upper mantle generated intraplate seamount groups in the West Pacific
An oceanic volcanic chain with linear age–distance relationships is generally attributed to
originate from a primary mantle plume. The origin of many seamount groups in the West …

When a plateau suppresses a plume: Disappearance of the Samoan plume under the Ontong Java Plateau
The Samoan hotspot generated an age‐progressive volcanic track that can be traced back
to 24 Ma at Alexa Bank, but the trace of the older portion (> 24 Ma) of the hotspot track is …

[HTML][HTML] The isotopic origin of Lord Howe Island reveals secondary mantle plume twinning in the Tasman Sea
Thermochemical convective instabilities in the mantle, often referred to as mantle plumes,
cause mantle melting that give rise to ocean island basalts (OIB) in intraplate settings. The …

Four distinct pulses of volcanism built the Melanesian Border Plateau: Implications for oceanic mid-plate superstructure formation
The ocean basins contain numerous volcanic ridges, seamounts and large igneous
provinces (LIPs). Numerous studies have focused on the origin of seamount chains and LIPs …

Toroidal flow around the Tonga slab moved the Samoan plume during the Pliocene
Age-progressive seamount tracks generated by lithospheric motion over a stationary mantle
plume have long been used to reconstruct absolute plate motion (APM) models. However …

The longest-lived Pacific hotspots reveal a plume tail for the largest oceanic plateau
JG Konter, V Finlayson, K Konrad, MG Jackson… - 2023 - eartharxiv.org
Volcanic hotspots are thought to initially form by melting in an upwelling mantle plume head
followed by melting of the plume tail. Plate motion then generates an age progressive …
