Exempel på hur man kan använda TEPHRAS i en mening

• Volcanism during the Holocene produced a series of pumiceous tephras, tuff rings, lava domes, and lava flows.
• There are also tephras derived from the andesitic stratovolcanoes of the Tongariro and Taranaki regions, as well as from Mayor Island/Tuhua.
• Varve count dating has indicated that tephras in Lake Villarrica and Lake Calafquen erupted presumably in 1591 are compositionally similar to Huanquihue scorias.
• They are both phonolitic to trachytic in composition and high in iron(II) oxide, indicating that the tephras were possibly erupted from a single volcano.
• The tephras deposited by past eruptions of the Volcanic Eifel are lithological deposits that are radiometrically dateable via argon-argon dating of K-feldspar grains.
• 2,320 ± 100 and 7,450 ± 500 BCE large Plinian eruptions with a volcanic explosivity index of 5 generated the MB2 and MB1 tephras, respectively.
• The lavas emitted by the Svartsengi are exclusively basalts—notably picrite and tholeite—and emerge through effusive eruptions with a volcanic explosivity index of 1 to 3, which produce lava flows and limited projections of tephras.
