Experiments on the taphonomy of tephra in peat [PDF]
, 2005 Understanding the taphonomy of tephra (volcanic ash) is crucial to the use of tephrochronology in peatlands. This study uses field experiments on a Scottish peatland to investigate the post-depositional movement of tephra in peat. Experiments were designed to investigate the temporal change in tephra profiles over a 24-month study period, the ...

Tephra Sequence with Mica Flakes
Annals of The Tohoku Geographycal Asocciation, 1970 In the northern half of Kitakami Mountains, some tephra sequences composed of micaceous clayey volcanic ashes and pumice layers without mica flakes are observed. These sections are situated at hill foots and presented within exposed regions of granitic rocks.Pumice grains fell and settled relatively in short time and, on the contrary, falling and ...

The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]
, 2013 The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is

The Omachi Tephra Formations and Tephrochronology
The Quaternary Research (Daiyonki-Kenkyu), 1972 The tephras supplied from Late Quaternary volcanoes in Central Japan have been distinguished into some tephra regions. In this paper, the author has made the characterization, classification and tephrochronologic consideration of the Omachi Tephra formations, which are developed in the Omachi Tephra region.
