Quaternary Tephrochronology in the Mediterranean Region

1981
Quaternary volcanism in the Mediterranean region was highly explosive, especially in the Roman-Campanian province, the Aeolian Islands and the Hellenic island arc. Pantelleria and Etna were less explosive. Tephra layers originating from all of these volcanoes have been encountered in Quaternary sediments.

Tephrochronology and Palaeoecology: The Value of Isochrones

1981
The applications of tephrochronology to the correlation of temporally similar yet spatially disjunct flora and fauna are discussed, using as examples recent work in Iceland and Kenya. The paucity of such studies is noted and its relevance to studies in palaeoecology and island biogeography commented upon.

The Application of Tephrochronology in Iceland

1981
The situation in Iceland for establishing a tephrochronological time scale is very good. This is due to the great number of volcanic eruptions in post glacial time, a great range of variation in chemistry between tephra layers, a rapid thickening of the soil, separating layers with small age difference, and the existence of detailed accounts of many ...

3 Katla: Tephrochronology and Eruption History

2010
Abstract The Holocene eruption history of the Katla volcanic system and the ensuing environmental changes are revealed in two archives: in written documents and in its volcanic products. Hydromagmatic explosive basaltic eruptions on fissures below Mýrdalsjokull are the dominant mode of activity, explosive silicic eruptions occur sporadically and ...

The Interrelationship between Magnetostratigraphy and Tephrochronology

1981
Magnetostratigraphy and tephrochronology represent complementary techniques for the determination of the ages of sedimentary sequences. Each method is subject to its own limitations. The magnetic polarity zonation of a sequence may not be sufficiently characteristic to correlate it to the magnetic polarity time scale.

Tephrochronology and Quaternary Studies in Japan

1981
This paper gives an overview of the development of tephrochronology in Japan and discusses several problems regarding the Japanese Quaternary. Tephra from Quaternary stratovolcanoes in Japan is mainly of andesitic composition with subordinate amounts of basalt and rhyolite. In contrast, the eruptions causing the formation of calderas are of rhyodacitic
