Abstract
Stalagmite
luminescence
excitation
emission
wavelength
timeseries
can
provide
high-resolution
palaeoclimate
records.
Here,
we
employ
multidimensional
visualisation
techniques
in
order
to
interpret
a
10,000
year
luminescence
record
from
a
stalagmite
from
Crag
Cave,
SW
Ireland.
Our
results
demonstrate
three
periods
of
distinct
luminescence
properties:
(1)
0-4,000
BP,
when
they
are
affected
by
overlying
agriculture.
(2)
4,000-9,600
BP,
where
there
is
a
strong
correlation
between
luminescence
and
isotopic
variations;
we
suggest
the
correlation
demonstrates
a
vegetation
response
to
climate
change,
(3)
Before
9,600
BP,
where
a
strong
early
Holocene
transition
is
visible.
Our
results
suggest
that
it
took
about
400-600
years
for
soils
above
the
cave
to
stabilise
after
significant
climate
or
environmental
change,
and
that
there
was
a
complex
vegetation
response
between
8,000
and
7,100
BP
that
my
have
been
a
lagged
response
to
the
"8.2
ka
event"
