From: Roger Morrison, Chair, Pedostratigraphy Work Group

This ia a repeat of an article that was somewhat garbled in e-mail
transmission several days ago. I hope that this comes through with
better collation.

ORIGINAL MESSAGE

The attachment below was prepared in response to e-mail that I've lately
received from workers all over the world, commenting on what
pedostratigraphic units are like in their work areas, how they ought to
be defined, and other problems in pedsostratigraphy. To provide a basis
for discussion, I start with explaining how the current North American
Stratigraphic Code defines pedostratigraphic units and geosols. These
definitions are by no means immutable; they aren't set in concrete; in
fact, they are constantly being revised in light of more advanced
information and judgement. I've tried to address a few key issues in as
simple terms as possible, but please excuse my at times obscure
semantics. I hope that this material will be helpful during discussions
of the Paleopedology Commission in Durban, South Africa in August --
which I plan to attend.
