The meaning of BACK-ARC is a geological region that forms at a subduction zone when the overriding plate thins and begins to spread out —often used before another noun. How to use back-arc in a sentence.
(e.g. Oiso Hill) and large volcanoes (e.g. Hakone volcano) are located near the back of the shoreline. The Sagami River and other rivers flow down a steep gradient into Sagami Bay. The northernmost part of Sagami Bay is one of the most active areas of crustal movement in Japan. For...
Whether arc magmatism occurs above oceanic subduction zones is the forefront of studies on convergent plate margins. The most important petrologic issue related to the evolution of arc systems is the origin of arc magmatism, among which arc basalts are the most important one because they provide in...
Mafic lavas were selected primarily in portions of the Kamchatka arc where the HESC is subducting, from Holocene volcanoes across the arc front (Eastern Volcanic Front: EVF), the Central Kamchatka Depression (CKD) and the Sredinny Ridge (SR) in the back arc. The slab depth varies from 100...
Forecasting explosive eruptions relies on using monitoring data to interpret the patterns and timescales of magma transport and mixing. In September 2017, a distal seismic swarm triggered the evacuation of around 140,000 people from Agung volcano, Bali.
When the analysis showed common Pb contents significantly above the detection limit, age-related common Pb correction, according to Stacey and Kramers (1975), was used. Signal strengths on mass 206 were typically 100,000 cps, depending on the uranium content and age of the zircon. U/Pb ...
Smith1 The formation of amphibole cumulates beneath arc volcanoes is a key control on magma geochemistry, and generates a hydrous lower crust. Despite being widely inferred from trace element geochemistry as a major lower crustal phase, amphibole is neither abundant nor common as a phenocryst ...

Narcondam Island represents a dormant inner arc volcano of the active Andaman–Java Subduction Complex in the Andaman Sea. The Narcondam volcano along with the active Barren volcano lies in the chain of inner arc volcanoes extending from Burma to Indonesia. The Narcondam volcanics are represente...
