\description{
From Greek \emph{leimon} = meadow. A subaqueous / wet-meadow horizon
showing accumulation of secondary Fe/Mn (oxi)hydroxides from
fluctuating redox cycles. Distinct from \emph{limnic material}
(Ch 3.3.10), which is the parent material; the limonic horizon is
the \emph{soil} horizon derived from such material plus subsequent
pedogenesis.
