Distribution, chemical composition and sources of Oligocene to Miocene volcanic ashes from sites 907, 908 and 913 / Reinhard Werner, Hans-Joachim Wallrabe-Adams, Christian Lacasse, Hans-Ulrich Schmincke, Jörn Thiede.
Title: | Distribution, chemical composition and sources of Oligocene to Miocene volcanic ashes from sites 907, 908 and 913 / Reinhard Werner, Hans-Joachim Wallrabe-Adams, Christian Lacasse, Hans-Ulrich Schmincke, Jörn Thiede. |
Author(s): | Werner, Reinhard. Wallrabe-Adams, Hans-Joachim. Lacasse, Christian. Schmincke, Hans-Ulrich. Thiede, Jörn. |
Date: | 1993. |
In: | Ocean Drilling Program. Proceedings. Scientific Results. (1993.), Vol. 151(18) (1993) |
Abstract: | Volcanic component of 54 ash layers and ashy sediments consists mainly of colourless and/or brown glass particles, with some crystals and lithics. Colourless glass shards are primarily bubble walls and pumice. Compositions are subalkalic and low-K subalkalic basaltic, basaltic-andesitic, andesitic, dacitic and trachytic, with low-K and high-K rhyolitic. Last two can be attributed to highly explosive Plinian eruptions. Major elements show that most ash layers are from Iceland or, less so, Jan Mayen System. There was short, strong increase in explosions during late middle Miocene. |
