Pyroclastic Density Currents and the Sedimentation of ...
Ground-hugging pyroclastic density currents produce a buoyant counterpart,
known as a phoenix cloud or co- ignimbrite ash plume, which can carry ash and
aerosols into the stratosphere and so cause significant climatic perturbation.

The variation in percent porosity is reflected in the independently determined (
see above) welding zonation of the ignimbrite (Fig. 4). Throughout most of the
outcrop area, the ignimbrite forms a single, apparently simple cooling unit. There
are ...

Joel L. Pederson, Carol Merritt Dehler. Themes to consider: Is the orange tuff an
upper nonwelded part of the ignimbrite (note the Grey's Landing ignimbrite
generally lacks pumice lapilli), or is it an ashfall deposit (e.g., of co-ignimbrite
origin)?
