The Manihiki Plateau is an elevated oceanic volcanic plateau that was formed mostly in Early Cretaceous time by hotspot activity. We analyze new seismic reflection data acquired on cruise KIWI 12 over the High Plateau region in the southeast of the plateau, to look for direct evidence of the location of the heat source and the timing of uplift, subsidence and faulting. These data are correlated...
متن کاملBoninite-like intraplate magmas from Manihiki Plateau require ultra-depleted and enriched source components
The Ontong Java and Manihiki oceanic plateaus are believed to have formed through high-degree melting of a mantle plume head. Boninite-like, low-Ti basement rocks at Manihiki, however, imply a more complex magma genesis compared with Ontong Java basement lavas that can be generated by ∼30% melting of a primitive mantle source. Here we show that the trace element and isotope compositions of low-...
متن کاملInteractions of Mechanical Controls on Magma Emplacement with the Petrology of Volcanic Edifice - building Flows on
Introduction: Large volcanic edifices on Venus constitute a primary expression of the thermal evolution of that planet. Over 150 volcanic edifices with diameters > 100 km are distributed heterogeneously over the surface of Venus [1-4]. They are characterized by extensive radially oriented lava flow aprons and generally shallow flank slopes. The compositions of the lava flows that build such str...
متن کاملGravity Observations of the Aristarchus Plateau on the Moon: Implications for the Volcanic and Impact Histories of the Plateau
Introduction The Aristarchus Plateau (Figure 1) is a distinctive, geologically complex volcanic highland in northern Oceanus Procellarum. It is roughly diamond shaped, 170 by 220 km across, and up to 2 km higher than the surrounding mare [1, 2]. The roughly linear edges of the plateau suggest that it is fault bounded. The plateau edges are essentially radial and concentric to the center of the ...
متن کاملMare Tranquillitatis: Basalt emplacement history and relation to lunar samples
Galileo and Clementine multispectral data of the Mare Tranquillitatis region have been analyzed to investigate the stratigraphy of basaltic units and the effects of lateral and vertical mixing processes within the mare. The distribution of compositionally distinct mare units is observed to be correlated with previous UV/VIS ratio images, although estimates of soil titanium contents are low in s...
