Abstract

The Amsterdam‐Saint Paul plateau results from a 10 Myr interaction between the South East Indian Ridge and the Amsterdam‐Saint Paul hot spot. During this period of time, the structure of the plateau changed as a consequence of changes in both the ridge‐hot spot relative distance and in the strength of the hot spot source. The joint analysis of gravity‐derived crust thickness and bathymetry reveals that the plateau started to form at ∼10 Ma by an increase of the crustal production at the ridge axis, due to the nearby hot spot. This phase, which lasted 3–4 Myr, corresponds to a period of a strong hot spot source, maybe due to a high temperature or material flux, and decreasing ridge‐hot spot distance. A second phase, between ∼6 and ∼3 Ma, corresponds to a decrease in the ridge crustal production. During this period, the hot spot center was close to the ridge axis and this reduced magmatic activity suggests a weak hot spot source. At ∼3 Ma, the ridge was located approximately above the hot spot center. An increase in the hot spot source strength then resulted in the building of the shallower part of the plateau. The variations of the melt production at the ridge axis through time resulted in variations in crustal thickness but also in changes in the ridge morphology. The two periods of increased melt production correspond to smooth ridge morphology, characterized by axial highs, while the intermediate period corresponds to a rougher, rift‐valley morphology. These variations reveal changes in axial thermal structure due to higher melting production rates and temperatures.

<abstract><p>The Amsterdam‐Saint Paul plateau results from a 10 Myr interaction between the South East Indian Ridge and the Amsterdam‐Saint Paul hot spot. During this period of time, the structure of the plateau changed as a consequence of changes in both the ridge‐hot spot relative distance and in the strength of the hot spot source. The joint analysis of gravity‐derived crust thickness and bathymetry reveals that the plateau started to form at ∼10 Ma by an increase of the crustal production at the ridge axis, due to the nearby hot spot. This phase, which lasted 3–4 Myr, corresponds to a period of a strong hot spot source, maybe due to a high temperature or material flux, and decreasing ridge‐hot spot distance. A second phase, between ∼6 and ∼3 Ma, corresponds to a decrease in the ridge crustal production. During this period, the hot spot center was close to the ridge axis and this reduced magmatic activity suggests a weak hot spot source. At ∼3 Ma, the ridge was located approximately above the hot spot center. An increase in the hot spot source strength then resulted in the building of the shallower part of the plateau. The variations of the melt production at the ridge axis through time resulted in variations in crustal thickness but also in changes in the ridge morphology. The two periods of increased melt production correspond to smooth ridge morphology, characterized by axial highs, while the intermediate period corresponds to a rougher, rift‐valley morphology. These variations reveal changes in axial thermal structure due to higher melting production rates and temperatures.</p>

<abstractGroup><abstract type="main"><p xml:id="jgrb16656-para-0001" label="1">The Amsterdam‐Saint Paul plateau results from a 10 Myr interaction between the South East Indian Ridge and the Amsterdam‐Saint Paul hot spot. During this period of time, the structure of the plateau changed as a consequence of changes in both the ridge‐hot spot relative distance and in the strength of the hot spot source. The joint analysis of gravity‐derived crust thickness and bathymetry reveals that the plateau started to form at ∼10 Ma by an increase of the crustal production at the ridge axis, due to the nearby hot spot. This phase, which lasted 3–4 Myr, corresponds to a period of a strong hot spot source, maybe due to a high temperature or material flux, and decreasing ridge‐hot spot distance. A second phase, between ∼6 and ∼3 Ma, corresponds to a decrease in the ridge crustal production. During this period, the hot spot center was close to the ridge axis and this reduced magmatic activity suggests a weak hot spot source. At ∼3 Ma, the ridge was located approximately above the hot spot center. An increase in the hot spot source strength then resulted in the building of the shallower part of the plateau. The variations of the melt production at the ridge axis through time resulted in variations in crustal thickness but also in changes in the ridge morphology. The two periods of increased melt production correspond to smooth ridge morphology, characterized by axial highs, while the intermediate period corresponds to a rougher, rift‐valley morphology. These variations reveal changes in axial thermal structure due to higher melting production rates and temperatures.</p>

<abstract>The Amsterdam‐Saint Paul plateau results from a 10 Myr interaction between the South East Indian Ridge and the Amsterdam‐Saint Paul hot spot. During this period of time, the structure of the plateau changed as a consequence of changes in both the ridge‐hot spot relative distance and in the strength of the hot spot source. The joint analysis of gravity‐derived crust thickness and bathymetry reveals that the plateau started to form at ∼10 Ma by an increase of the crustal production at the ridge axis, due to the nearby hot spot. This phase, which lasted 3–4 Myr, corresponds to a period of a strong hot spot source, maybe due to a high temperature or material flux, and decreasing ridge‐hot spot distance. A second phase, between ∼6 and ∼3 Ma, corresponds to a decrease in the ridge crustal production. During this period, the hot spot center was close to the ridge axis and this reduced magmatic activity suggests a weak hot spot source. At ∼3 Ma, the ridge was located approximately above the hot spot center. An increase in the hot spot source strength then resulted in the building of the shallower part of the plateau. The variations of the melt production at the ridge axis through time resulted in variations in crustal thickness but also in changes in the ridge morphology. The two periods of increased melt production correspond to smooth ridge morphology, characterized by axial highs, while the intermediate period corresponds to a rougher, rift‐valley morphology. These variations reveal changes in axial thermal structure due to higher melting production rates and temperatures.</abstract>
