Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen Open
The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust un…

The 1956 eruption of Bezymianny volcano (Kamchatka). Part II—Magma dynamics and timescales from crystal records Open
Laterally directed blasts are explosive events following a major sector collapse of a volcano, with the potential for devastating areas of several hundred km 2 , due to powerful dilute and turbulent pyroclastic density currents. The catast…

The 1956 eruption of Bezymianny volcano (Kamchatka). Part I - Petrological constraints on magma storage and eruptive dynamics Open
Bezymianny volcano is an andesitic island arc stratovolcano that started to erupt in 1955 after ~ 1000 years of dormancy. The March 30, 1956, the climactic phase of the eruption was preceded by a four-month-long emplacement of a shallow cr…

Numerical modelling of magmatic CO2 emissions from the Neo-Tethyan margin during the Early Cenozoic Open
Identifying the geological drivers of long-term climate change is key to improve our understanding of the interactions between the deep Earth and the Earth’s surface. Long-term Cenozoic climate cooling has been largely attributed to …

Quantification of the pre-eruptive CO2 budget of Neo-Tethyan magmas and their forcing on Early Cenozoic global climate Open
Magmatic CO2 emissions can affect the atmosphere composition, thereby driving long term global climate changes. Early Cenozoic climate trends are generally associated with changes in global silicate weathering related to the India-Asia con…

Diffuse CO2 degassing monitoring of the Tenerife North-South Rift Zone (NSRZ) volcano, Canary Islands Open
Tenerife (2,034 km2), the largest and one of the most active islands of the Canarian volcanic archipelago, has registered six volcanic eruptions in the last 500 years. One of the main volcano-structural and geomorphological features of Ten…

New constraints on the Neo-Tethyan carbon cycling and its forcing of early Cenozoic climate Open
Cenozoic climate trends are classically ascribed to variations of the geological carbon cycle related to Neo-Tethyan geodynamics. It is widely agreed that the collision of India and Arabia with Asia and associated mountain uplift enhanced …

The role of mixing and crystallization in the differentiation of magmatic systems Open
Understanding magma differentiation and formation of eruptible magmas is one of the key issues in Earth sciences. Many studies have either focused on mixing or crystallization, but none have studied these two processes simultaneously. Here…

Intra-crustal Mantle in the Himalayan-Tibetan Orogen Open
The Himalayan-Tibetan mountains raised due to doubling of the continental crust during the India-Asia collision, which is often assumed to have occurred by underthrusting of the Indian crust directly below the Asian crust. However, this mo…

Pre-eruptive CO<sub>2</sub> budget of lower Cenozoic Neo-Tethyan magmas Open
Plate tectonics and magmatism are linked to the evolution of climate and life as volcanoes are sources of surface carbon by releasing volcanic gases (by volcanic outgassing; CO 2 , H 2 O, halogens) from their vent before, during or after e…

Insights Into Volcanic Unrest by Correlating Petrological and Seismic Observations at Kizimen (Kamchatka, Russia) Open
The increase of number and intensity of earthquakes during a pre-eruptive crisis is the main basis of seismic volcano monitoring. However, the exact relationship between the seismic activity and the volcano-magmatic processes remains uncle…

Spatio-temporal dynamics of the magmatic plumbing systems, towards an « early-warning clock ». Application to Dominica island (Lesser Antilles) and Kamchatka (Russia) Open
Volcanic eruptions are among the most devastating events on Earth. In a subduction context, eruptions generally involve differentiated magmas: after long repose times in magma reservoirs, basic magmas resulting from the partial melting of …

Time-window into the transcrustal plumbing system dynamics of Dominica (Lesser Antilles) Open
Dominica, one of the most magmatically active islands of the Lesser Antilles through its four active volcanoes, is likely host under its central part, below Morne Trois Pitons–Micotrin, to a well-established transcrustal mush system. Pre-e…

A System Dynamics Approach to Understanding the deep Magma Plumbing System Beneath Dominica (Lesser Antilles) Open
To understand the dynamics of magmatic systems, one must first seek to characterize the time-dependent behavior of magma storage and ascent. Herein, we do this through a combination of the Crystal System Approach and careful study of Fe-Mg…
