Why Archaean TTG cannot be generated by MORB melting in subduction zones

Hervé Martin, +10 more
- 01 Jun 2014 - 
TL;DR: However, recent geochemical and experimental evidences indicate that formation of TTG-like basalts required a LILE-enriched source, similar to oceanic plateau basalts as mentioned in this paper.
Journal ArticleDOI

Ignimbrites of Cappadocia (Central Anatolia, Turkey): petrology and geochemistry

Abidin Temel, +3 more
- 01 Oct 1998 - 
TL;DR: In Cappadocia (Central Anatolia, Turkey), high-K calc-alkaline volcanic rocks have a volume of at least 1000 km3 and cover an area of about 40,000 km2 as discussed by the authors.
Journal ArticleDOI

Petrological analysis of the pre-eruptive magmatic process prior to the 2006 explosive eruptions at Tungurahua volcano (Ecuador)

Pablo Samaniego, +5 more
- 01 Jan 2011 - 
TL;DR: The case of Tungurahua volcano has been studied in this article, where thermobarometric data point to magmatic temperatures ranging from 950 to 1015°C and pressures in the range of 200 to 250 MPa, which corresponds to 7.5-9.5 km below the summit.
Journal ArticleDOI

Causes and consequences of bimodal grain-size distribution of tephra fall deposited during the August 2006 Tungurahua eruption (Ecuador)

Julia Eychenne, +4 more
- 01 Jan 2012 - 
TL;DR: In this paper, a new grain-size deconvolution algorithm and an extended sampling area were proposed to account for the bimodal grain size distribution in the Tungurahua eruption.
Journal ArticleDOI

Estimating rates of decompression from textures of erupted ash particles produced by 1999–2006 eruptions of Tungurahua volcano, Ecuador

Heather M. N. Wright, +5 more
- 01 Jul 2012 - 
TL;DR: In this paper, crystal textures of ash particles from 1999 to 2006 Vulcanian and Strombolian eruptions of Tungurahua volcano, Ecuador, provide quantitative information about the dynamics of magma ascent and eruption that is difficult to obtain from other monitoring approaches.
