a r t i c l e i n f o Satellite Radar Interferometry (InSAR) is suited to monitoring ground deformation on the scale of volcanic arcs, providing insight into the eruptive cycle over both long and short time periods. However, these measurements are often contaminated with atmospheric artefacts caused by changes in the refractivity of the atmosphere. Here, we test the use of two large-scale atmos...

19 Detrital-zircon analysis of sandstones interbedded with ca 464 Ma ignimbrites in 20 the lower Mweelrea Formation of the South Mayo Trough, western Ireland, 21 suggests Ordovician source-rock provenance that corresponds to two distinct 22 volcanic-arc phases on the Laurentian margin. East-derived sandstones contain a 23 suite of zircons with a mean age of ca 487 Ma that suggests derivation fr...

We present the first two-dimensional (2-D) spatial distribution of seismic scattering and intrinsic attenuation beneath Aeolian Islands arc. The archipelago represents one best examples a small dimension volcanic island arc characterised by alternation different structural domains. Using wave diffusion model as basis for analysis, using data from an active experiment (TOMO-ETNA), we analysed mo...

The Aleutian Arc is remote and highly active volcanically. Its 4,000 km extent from mainland Alaska to Russia’s Kamchatka peninsula hosts over 140 volcanic centers of which about 50 have erupted in historic times. We present data gas samples emission measurements obtained during an expedition the western-most segment arc September 2015 order extend sparse knowledge on volatile emissions this bu...

Abstract The South Banda back-arc basin is a morphotectonic environment that part of the Basin, characterized by flat morphology with depths ranging from 5000m to 6000m. purpose this paper analyze and relate morphometric aspects Quaternary seabed sediment deposits deposited in an active tectonic Sea area, including information on type its distribution as well relation volcanic hosted-massive su...

gabal el-zeit block at the western coast of the gulf of suez region in egypt consists of two varieties of precambrian granites, namely monzogranite and a peripheral zone of alkali granite. both granitic varieties display moderate (60.1-68.5 wt%) and high silica (73.36-76.16 wt%) contents with high na2o+k2o (7.21-8.61 wt%), respectively. the investigated monzogranite is calc-alkaline metaluminou...
