Offshore Record of Explosive Volcanic Eruptions in the Southern Part of the Panamá Basin During the Past 10 Myr: 1. Tephrostratigraphy, Cross‐Correlations and Geochemical Characterization

Geochemistry, Geophysics, Geosystems
Northern Andean volcanism is characterized by an intense Quaternary activity, whose onshore deposits have partly covered Mio‐Pliocene products associated with the early development of the arc, making it difficult to obtain an exhaustive catalog of past ...

Tephrochronology: principles, functioning, application

, 2011
Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic or archaeological sequences or events. The method relies firstly and fundamentally on stratigraphy and the law of superposition, which apply in any ...
