Abstract:

The explosive events in Teide Pico Viejo (TPV) complex in Tenerife Island (Spain) have traditionally been restricted to the subplinian eruption of Montaña Blanca, which occurred about 2000 years ago. A recent revision of the stratigraphy of TPV shows that phonolitic explosive activity has been significant during the Holocene, with several distinct episodes related to eruptions ranging from Strombolian to sub-plinian. Using field, mineralogical and geochemical stratigraphic correlations, we have identified 11 phonolitic explosive eruptions related to the satellite domes present all around TPV

Abstract:

This study assesses the geological constraints on fluid flow within the main crater of Whakaari volcano (White Island) which is located in the Bay of Plenty, New Zealand. A review of the volcanological and morphological history, field mapping, and permeability experiments were used to propose a model for single-state (gas or liquid water) fluid flow in the volcano. Three structural scales were of most importance: (a) the elongate main crater (1.2 km by 0.5 km); which contains (b) three subcraters (~300-500 m in diameter); and (c) >14 historic eruption craters and crater complexes (30-300 m in

The lower stratigraphy of both successions is described here for the first time, and is divided into soil-bound eruption-units.

Volcanic rocks from Sao Miguel form two distinct alkaline (potassic) magma series. Recent eruptives comprise Ne-normative basalts and derivatives (Main Series). Older basalts associated with the extinct stratovolcano Povoacao are either Ne or Hy-normative (Povoacao Series ) and have lower P/Zr, Ba/Zr and Sr/Zr ratios. Faial volcanic rocks form a single series, basaltic compositions being Ne-normative. Differentiates on both islands range through intermediate compositions to metaluminous and peralkaline trachytes. The latter are strongly enriched in the incompatible elements (eg Th, Rb, Ta, Nb,

Abstract:

Monogenetic volcanism is characterized by a large diversity of eruptive styles, morphologies and deposits. Monogenetic landforms are the result of a complex merging of internal (magma composition, vesiculation) and external (geological setting, fracturation, hydrogeology, substrate stratigraphy, etc) parameters that govern the physics of the eruptions. Changes in these parameters may cause variations in the eruption style several times during the course of such short-lived volcanoes. Monogenetic volcanoes may form in any type of geological environment with scoria cones being the most common vo

Abstract:

Lead isotope compositions have been obtained from five major volcanic and intrusive rock suites and several ore deposits on Vancouver Island. Lead, uranium and thorium concentrations and strontium isotope ratios have been obtained for a subset of these samples. The rock suites examined are the Paleozoic Sicker Group, Triassic Karmutsen Formation, Jurassic Island Intrusions and Bonanza Group volcanic rocks, and the Eocene Catface intrusions. Isotope geochemistry of the Sicker Group is consistent with the interpretation that it formed as an island arc. Relatively high 207pb/204pb ratios indicate

Abstract:

The amount of volatile elements dissolved in silicate melts is a controlling factor in a range of geologic processes, which include hazardous volcanic eruptions, economically-significant ore-forming systems, and global-scale volatile fluxes, which contribute to planetary evolution. While melt volatile contents are important, estimating the origin and fate of volatiles distributed within magmas is challenging because volatiles exsolve from the melt during eruption and are transferred into the atmosphere. Therefore, the stratigraphic record of volcanic and intrusive deposits does not contain dir

Abstract:

White Island is a highly active volcano with an acidic, S-rich hydrothermal system in the Bay of Plenty, North Island, New Zealand. In this acidic environment a series of subsurface Fe-rich layers are ubiquitous in the crater sediments at shallow depth and are capable of modifying the flow and gas flux dynamics in the system. The mineralogy of the subsurface Fe-rich layer(s) and the processes leading to their formation are unknown. Here the mineralogy and formation of the subsurface Fe-rich layers in relation to the surface and subsurface environment(s) within the Main Crater at White Island a

Abstract:

Ce travail consiste en une étude de déformation portant sur le Nord de l'Islande, en employant la méthode InSAR DIAPASON, sur la période post-rifting (92-02) qui fait suite à l'épisode de rifting majeur de Krafla (75-94). Deux types de signaux ont été identifiés : - un signal local, autour du volcan Krafla, affectant une zone de 10 x 30 km, et marqué par un mouvement essentiellement subsidant de vitesse constante (3 cm. An-1 au maximum). Ce signal posséderait une source peu profonde (entre 6 et 3 km) composée d'une chambre magmatique prolongée au Nord et au Sud par des sills. - un signal régio
