Early arc crust formation preserved in the Grenadines archipelago, southern Lesser Antilles arc Open
Intra-arc diversity in volcanic activity and composition is ubiquitous, but its underlying causes remain largely unresolved in many settings. In this work, we examine such variability in the Grenadines archipelago, southern Lesser Antilles…
The effect of variations in cooling rates on mineral compositions in mid-ocean ridge basalts Open
We present textural and chemical analyses of minerals from a 150 m thick sequence of submarine mid-ocean ridge basalts from the South China Sea in order to showcase the effect of variations in magma cooling rates on mineral texture and min…
Continental breakup style of Marginal Seas Open
Marginal Seas are extensional basins formed in a convergent setting near active subduction zones. They are characterized by a short life (In this contribution, we characterize the tectono-magmatic processes acting during continental breaku…

IODP Expedition 351, Hole U1438F - Well Logging Data Open
Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, …

Formation of the Alpine Orogen by Amagmatic Convergence and Assembly of Previously Rifted Lithosphere Open
The tectonic and magmatic characteristics of the Alps and Pyrenees during convergence are quite distinct from characteristics associated with classic Benioff-type oceanic subduction. From the initiation of subduction at passive margins unt…

Basalt derived from highly refractory mantle sources during early Izu-Bonin-Mariana arc development Open
The character of magmatism associated with the early stages of subduction zone and island arc development is unlike that of mature systems, being dominated in the Izu-Bonon-Mariana (IBM) case by low-Ti-K tholeiitic basalts and boninites. B…
Revisiting the Australian‐Antarctic Ocean‐Continent Transition Zone Using Petrological and Geophysical Characterization of Exhumed Subcontinental Mantle Open
The final lithospheric breakup of the Australian‐Antarctic rift system remains controversial due to sparse geological constraints on the nature of the basement along the ocean‐continent transition (OCT) zones. We present new interpretation…
Ca isotopes record rapid crystal growth in volcanic and subvolcanic systems Open
Significance Timescale estimates for crystal growth in volcanic systems, which are generally much shorter than absolute crystal ages, are thought to be shortest in mafic (vs. silicic) systems. However, this result may be influenced by assu…
Evidence for ancient fractional melting, cryptic refertilization and rapid exhumation of Tethyan mantle (Civrari Ophiolite, NW Italy) Open
Western Tethyan peridotites exposed in the European Alps show limited amounts of partial melting and mostly fertile compositions. Here we investigate the Civrari Ophiolite (northwestern Italy), which is composed of depleted spinel-harzburg…
Isotopic Characteristics of Neogene‐Quaternary Tephra From IODP Site U1438: A Record of Explosive Volcanic Activity in the Kyushu‐Ryukyu Arc Open
International Ocean Discovery program (IODP) Site U1438 is located within the Amami‐Sankaku Basin, ~50 km SW of the Kyushu‐Palau Ridge and ~500 km SE of the present‐day volcanic front of the Kyushu‐Ryukyu arc. Thirty‐eight rhyolitic tephra…
Subduction initiation without magmatism: The case of the missing Alpine magmatic arc Open
Models of orogens identify subduction of oceanic crust as the key mechanism leading to continental collision. Such models, based inter alia on thermobarometric and geochronological evidence preserved in high-pressure metamorphic rocks and …
