Quaternary Dating Methods
The technique most widely applied to determine the geochemical composition of
a tephra is electron probe micro-analysis (EPMA). The glass surface of each

Encyclopedia of Soil Science
Many distinct tephra layers are evident, disturbed by cryoturbation. Basaltic and
andesidic tephras are dark, but thin light colored rhyolitic tephras are also seen
near the middle and near the bottom of the profile. The soil contains considerable

We emphasise that "tephra" denotes essentially unconsolidated material, thus
welded (or hardened) pyroclastic materials, of either flow or airfall origin, should
not normally be described as "tephra". It is also our intention that unconsolidated

Ecological Responses to the 1980 Eruption of Mount St. Helens
Where tephra fell on snowpack, Le crust cracked as the snow melted. The
presence of cracks lowed us to map the snowpack in May 1980. Cracks filled

few days ...

Torrential rainfall on recently deposited tephra or other unconsolidated material
can also form lahars (Waldron, 1967). These types of lahars can also be
generated during eruptions by rainstorms related to convecting eruption columns
(Moore ...
